有关属性的描述根据 Player UI 中的相应部分进行分组：

• Icon
• Resolution and Presentation
• Splash Image
• Other Settings
• Publishing Settings

Icon

Use the Icon section to specify icons to represent your application on the device.

设置	描述
Adaptive	Specify textures of various sizes to represent your application on devices running Android 8.0 (API level 26) or higher.
Round	Specify textures of various sizes to represent your application on devices running Android 7.1 (API level 25) or higher.
Legacy	Specify textures of various sizes to represent your application on devices running versions earlier than Android 7.1 (API level 25).

Resolution and Presentation

Use the Resolution and Presentation section to customize aspects of the screen’s appearance.

设置		描述
Fullscreen Mode		Specifies how the window appears on the device. This sets the default window mode at startup.
	Fullscreen Window	The application window fills the full-screen native resolution of the device. To fill the full-screen window, Unity scales the application contents. Resolution Scaling Mode controls how Unity scales the contents. In this mode, the navigation bar is always hidden.
	Windowed	The application uses a standard, non-full-screen, movable window. The size of the window depends on the application’s resolution. In this mode, the window is resizable by default. To disable this, disable Resizable Window.
Resizable Window		Indicates whether the user can resize the application’s window. This setting enables multi-window capabilities in your application on Android phones and tablets. For more information, see Google’s developer documentation.
Default Window Width		The default width of the application window in pixels. This option is only available if the Fullscreen Mode is set to Windowed.
Default Window Height		The default height of the application window in pixels. This option is only available if the Fullscreen Mode is set to Windowed.
Minimum Window Width		The minimum width of the application window in pixels. This option is only available if the Fullscreen Mode is set to Windowed.
Minimum Window Height		The minimum height of the application window in pixels. This option is only available if the Fullscreen Mode is set to Windowed.
Hide Navigation Bar		Indicates whether to hide the navigation bar that appears at the top of the window.
Render outside safe area		Indicates whether the application should use all available screen space to render, including areas of the display that are cut out (notched). For more information, see Android’s display cutout support documentation.
Optimized Frame Pacing		Indicates whether Unity should evenly distribute frames for less variance in framerate. Enable this option to create a smoother experience.

Other Resolution and Presentation settings are grouped under the following sections:

• Resolution Scaling
• Supported Aspect Ratio
• Orientation
• Allowed Orientations for Auto Rotation
• Other

Resolution Scaling

Use the Resolution Scaling section to customize settings relating to screen resolution scaling. Using a resolution lower than the device’s native resolution can improve performance and battery life.

设置		描述
Resolution Scaling Mode		Specifies whether and how the application scales its resolution. You can set the scaling to be equal to or lower than the native screen resolution. Using a lower resolution can improve performance and battery life.
	Disabled	Doesn’t apply resolution scaling and the application renders to the device’s native screen resolution.
	FixedDPI	Applies resolution scaling using a target API. Use this to optimize performance and battery life or target a specific DPI setting.
	Letterboxed	Adds black bars to the rendered output so the content doesn’t stretch. This process is called letterboxing.
Target DPI		The resolution of the application. If the device’s native screen DPI is higher than this value, Unity downscales the application’s resolution to match this setting. To calculate the scale, Unity uses the following: min(Target DPI * Factor / Screen DPI, 1) Where Factor is the Resolution Scaling Fixed DPI Factor from Quality settings.Note: This option only appears when you set Resolution Scaling Mode to Fixed DPI.
Reset resolution on window resize		Indicates whether to set the screen resolution to the new native window size when the native window size changes. If you set Resolution Scaling Mode to Fixed DPI, Unity recalculates the resolution based on Fixed DPI property.
Blit Type		Controls whether to use a blit to render the final image to the screen. Using a blit is compatible with most devices but is usually slower than not using a blit.
	Always	Unity renders to an offscreen buffer and then uses a blit to copy the contents of the buffer to the device’s framebuffer. This is compatible with most devices but is usually slower than not using blit.
	Never	Unity renders to the framebuffer provided by the device’s operating system. If this fails, the application prints a one-time warning to the device log. This is usually faster than using blit, but it isn’t compatible with all devices.
	Auto	Unity renders to the framebuffer provided by the device’s operating system if possible. If this fails, Unity prints a warning to the device console and uses a blit to render the final image to the screen.

Supported Aspect Ratio

Use the Supported Aspect Ratio section to customize settings relating to which device aspect ratios to support.

设置		描述
Aspect Ratio Mode		Specifies the largest aspect ratio the application supports. If the device’s aspect ratio is greater than this aspect ratio, Unity uses this aspect ratio for the application and adds black bars so the application doesn’t stretch..
	Legacy Wide Screen (1.86)	The application supports aspect ratios up to Android’s legacy wide-screen aspect ratio.
	Native Aspect Ratio	The application supports aspect ratios up to Android’s native aspect ratio.
	Custom	The application supports aspect ratios up to the aspect ratio you set in Up To.
Up To		The custom maximum aspect ratio. This setting only appears when you set Aspect Ratio Mode to Custom.

Orientation

Use the Orientation section to customize settings relating to the orientation of the application on the device.

从 Default Orientation 下拉菜单中选择游戏的屏幕方向：

设置		描述
Default Orientation		Specifies the screen orientation the application uses. Note: Unity shares the value you set for this setting between Android and iOS.
	Portrait	The application uses portrait screen orientation where the bottom of the application’s window aligns with the bottom of the device’s screen.
	Portrait Upside Down	The application uses portrait screen orientation where the bottom of the application’s window aligns with the top of the device’s screen.
	Landscape Right	The application uses landscape screen orientation where the right side of the application’s window aligns with the bottom of the device’s screen.
	Landscape Left	The application uses landscape screen orientation where the right side of the application’s window aligns with the top of the device’s screen.
	Auto Rotation	The screen can rotate to any of the orientations you specify in the Allowed Orientations for Auto Rotation section.

Allowed Orientations for Auto Rotation

Use the Allowed Orientations for Auto Rotation section to specify which orientations the application supports when you set Default Orientation to Auto Rotation. This is useful, for example, to lock the application to landscape orientation but allow the user to switch between landscape left and landscape right.

This section only appears when you set Default Orientation to Auto Rotation.

设置	描述
Portrait	Indicates whether the application supports portrait screen orientation where the bottom of the application’s window aligns with the bottom of the device’s screen.
Portrait Upside Down	Indicates whether the application supports portrait screen orientation where the bottom of the application’s window aligns with the top of the device’s screen.
Landscape Right	Indicates whether the application supports landscape screen orientation where the right side of the application’s window aligns with the bottom of the device’s screen.
Landscape Left	Indicates whether the application supports landscape screen orientation where the right side of the application’s window aligns with the top of the device’s screen.

Other

The Resolution and Presentation section also contains the following general settings.

设置		描述
Use 32-bit Display Buffer		Indicates whether the display buffer holds 32-bit color values instead of 16-bit color values. Enable this setting if you see banding, or need alpha values in post-processing effects. Some post-processing effects require this because they create Render Textures in the same format as the display buffer.
Disable Depth and Stencil		Indicates whether to disable depth and stencil buffers.
Render Over Native UI		Indicates whether to render on top of native UI on Android or iOS. For this setting to take effect, set your Camera’s Clear Flags to use a solid color with an alpha value lower than 1.
Show Loading Indicator		Specifies if and how the loading indicator appears.
	Don’t Show	The loading indicator doesn’t appear.
	Large	A large loading indicator appears.
	Inversed Large	A large loading indicator appears with inversed color.
	Small	A small loading indicator appears.
	Inversed Small	A small loading indicator appears with inversed color.

Splash Image

Use the Virtual Reality Splash Image setting to select a custom splash image for Virtual Reality displays. For information on common Splash Screen settings, see Splash Screen.

以下是通用 Splash Screen 设置，可以设置特定于 Android 的 Static Splash Image 选项。

设置		描述
Image		Specifies the texture that the application uses for the Android splash screen. The standard size for the splash screen image is 320x480.
Scaling		Specifies how to scale the splash image to fit the devic’es screen.
	Center (only scale down	Draws the image at its native size unless it’s too large, in which case Unity scales the image down to fit.
	Scale to Fit (letter-boxed)	Scales the image so that the longer dimension fits the screen size exactly. Unity fills in the empty space around the sides in the shorter dimension in black.
	Scale to Fill (cropped)	Scales the image so that the shorter dimension fits the screen size exactly. Unity crops the image in the longer dimension.

渲染

使用这些设置可自定义 Unity 针对 Android 平台渲染游戏的方式。

设置		功能
Color Space		选择应该用于渲染的颜色空间，选项为：_Gamma_ 或 Linear。 请参阅线性渲染概述以了解这两者之间的区别。
Auto Graphics API		禁用此选项可手动设置图形 API。此选项在默认情况下为启用状态，并包含 Metal。
Color Gamut		可以为 iOS 平台添加或删除色域以用于渲染。单击加号 (+) 图标查看可用色域的列表。色域定义了给定设备（如监视器或屏幕）可以使用的所有颜色范围。sRGB 色域是默认色域（也是必需色域）。 如果目标设备是具备宽色域显示屏的新款 tvOS 设备，请使用 DisplayP3 充分利用显示能力。对于旧设备，使用 Metal Editor Support 作为后备选项。
Multithreaded Rendering		启用此选项可使用多线程渲染。仅 Metal 支持此功能。
Static Batching		启用此选项可使用静态批处理。
Dynamic Batching		选中此复选框可在构建中使用动态批处理（默认情况下启用）。
Compute Skinning		启用此选项可使用 DX11/ES3 GPU 计算蒙皮，这样可以释放 CPU 资源。
Graphics Jobs (Experimental)		启用此选项可指示 Unity 将图形任务（渲染循环）卸载到在其他 CPU 核心上运行的工作线程。此功能旨在减少主线程上 Camera.Render 所花费的时间，该时间通常成为瓶颈。 注意：此功能是实验性的。此功能可能无法为项目带来性能提升，并可能引入新的崩溃。
Texture compression format		Choose between ASTC, ETC2 and ETC (ETC1 for RGB, ETC2 for RGBA). See texture compression format overview for more information on how to pick the right format. See Texture compression settings for more details on how this interacts with the texture compression setting in the Build Settings.
Normal Map Encoding		选择 XYZ 或 DXT5nm 样式_对法线贴图编码进行设置。此设置影响用于法线贴图的编码方案和压缩格式。DXT5nm 样式_的法线贴图质量更高，但在着色器中解码成本更高。
Lightmap Encoding		选择 Low Quality、Normal Quality 或 High Quality 来设置光照贴图编码。此设置影响光照贴图的编码方案和压缩格式。
HDR Cubemap Encoding		Choose Low Quality, Normal Quality, or High Quality to set the HDR Cubemap encoding. This setting affects the encoding scheme and compression format of the HDR Cubemaps.
Lightmap Streaming Enabled		Whether to use Mipmap Streaming for lightmaps. Unity applies this setting to all lightmaps when it generates them. Note: To use this setting, you must enable the Texture Streaming Quality setting.
Streaming Priority		Set the priority for all lightmaps in the Mipmap Streaming system. Unity applies this setting to all lightmaps when it generates them. Positive numbers give higher priority. Valid values range from –128 to 127.
Enable Frame Timing Stats		启用此选项可收集 CPU/GPU 帧时序统计信息。
Virtual Texturing		Indicates whether to enable Virtual Texturing. Note: Virtual Texturing isn’t compatible with Android.
Shader precision model		Controls the default precision of samplers used in shaders. See Shader data types and precision for more details.

Vulkan Settings

Property	Description
SRGB Write Mode	Enable this option to allow Graphics.SetSRGBWrite() renderer to toggle the sRGB write mode during runtime. That is, if you want to temporarily turn off Linear-to-sRGB write color conversion, you can use this property to achieve that. Enabling this has a negative impact on performance on mobile tile-based GPUs; therefore, do NOT enable this for mobile.
Number of swapchain buffers	Set this option to 2 for double-buffering, or 3 for triple-buffering to use with Vulkan renderer. This setting may help with latency on some platforms, but in most cases you should not change this from the default value of 3. Double-buffering might have a negative impact on performance. Do not use this setting on Android.
Acquire swapchain image late as possible	If enabled, Vulkan delays acquiring the backbuffer until after it renders the frame to an offscreen image. Vulkan uses a staging image to achieve this. Enabling this setting causes an extra blit when presenting the backbuffer. This setting, in combination with double-buffering, can improve performance. However, it also can cause performance issues because the additional blit takes up bandwidth.
Recycle command buffers	Indicates whether to recycle or free CommandBuffers after Unity executes them.
Apply display rotation during rendering	Enable this to perform all rendering in the native orientation of the display. This has a performance benefit on many devices. For more information, see documentation on Framebuffer orientation.

Identification

属性	功能
Override Default Package Name	Indicates whether to override the default package name for your application. Note: This setting affects macOS, iOS, tvOS, and Android.
Package Name	Set the application ID, which uniquely identifies your app on the device and in Google Play Store. The application ID must follow the convention com.YourCompanyName.YourProductName and must contain only alphanumeric and underscore characters. Each segment must start with an alphabetical character. For more information, see Set the application ID. Important: Unity automatically removes any invalid characters you type. To set this property, enable Override Default Package Name.
Version	输入捆绑包的构建版本号，用于标识捆绑包的迭代（已发布或未发布）。版本以通用格式指定，该格式包含以点号分隔的数字的字符串（例如，4.3.2）。（在 iOS 和 Android 之间共享。）
Bundle Version Code	内部版本号。此数字仅用于确定一个版本是否比另一个版本更新，数字更大表示版本越新。这不是向用户显示的版本号；向用户显示的版本号由 versionName 属性设置。该值必须设置为整数，例如“100”。您可以根据需要定义，只要每个后续版本具有更高的数字即可。 例如，它可以是构建版本号。或者，可以通过在低 16 位和高 16 位分别编码“x”和“y”将“x.y”格式的版本号转换为整数。或者，每次发布新版本时，只需将数字加一。 如果启用了 Split APKs by target architecture，请将此数字保持在 100000 以下。每个 APK 必须具有唯一的版本代码，因此 Unity 为 ARMv7 添加 100000，为 ARM64 添加 200000。
Minimum API Level	运行应用程序所需的最低 Android 版本（API 级别）。
Target API Level	编译应用程序针对的目标 Android 版本（API 级别）。

配置

Property		Description
Scripting Backend		Choose the scripting backend you want to use. The scripting backend determines how Unity compiles and executes C# code in your Project.
	Mono	Compiles C# code into .NET Common Intermediate Language (CIL) and executes that CIL using a Common Language Runtime. For more information, see Mono.
	IL2CPP	Compiles C# code into CIL, converts the CIL to C++ and then compiles that C++ into native machine code, which executes directly at run time. See IL2CPP for more information.
API Compatibility Level	Choose which .NET APIs you can use in your project. This setting can affect compatibility with third-party libraries. However, it has no effect on Editor-specific code (code in an Editor directory, or within an Editor-specific Assembly Definition). Tip: If you are having problems with a third-party assembly, you can try the suggestion in the API Compatibility Level section below.
	.Net 2.0	.Net 2.0 libraries. Maximum .net compatibility, biggest file sizes. Part of the deprecated .NET 3.5 runtime.
	.Net 2.0 Subset	Subset of full .net compatibility, smaller file sizes. Part of the deprecated .NET 3.5 runtime.
	.Net Standard 2.0	Compatible with .NET Standard 2.0. Produces smaller builds and has full cross-platform support.
	.Net 4.x	Compatible with the .NET Framework 4 (which includes everything in the .NET Standard 2.0 profile as well as additional APIs). Choose this option when using libraries that access APIs not included in .NET Standard 2.0. Produces larger builds and any additional APIs available are not necessarily supported on all platforms. See Referencing additional class library assemblies for more information.
C++ Compiler Configuration		Choose the C++ compiler configuration used when compiling IL2CPP generated code. Note: This property is disabled unless Scripting Backend is set to IL2CPP.
Use incremental GC		Uses the incremental garbage collector, which spreads garbage collection over several frames to reduce garbage collection-related spikes in frame duration. For more information, see Automatic Memory Management.
Assembly Version Validation	Indicates whether Mono validates types from a strongly-named assembly.
Allow downloads over HTTP	Indicates whether to allow downloading content over HTTP. The options are Not allowed, Allowed in Development builds only, and Always allowed. The default option is Not allowed due to the recommended protocol being HTTPS, which is more secure.
Mute Other Audio Sources		Enable this option if you want your Unity application to stop Audio from applications running in the background. Otherwise, Audio from background applications continues to play alongside your Unity application.
Target Architectures		Select which CPUs you want to allow the application to run on (32-bit ARM, 64-bit ARM, 32-bit x86, and 64-bit x86–64). Note: Running Android apps in a 64-bit environment has performance benefits and 64-bit apps can address more than 4 GB of memory space.
Split APKs by target architecture (Experimental)		Enable this option to create a separate APK for each CPU architecture selected in Target Architectures. This makes download size smaller for Google Play Store users. This is primarily a Google Play store feature and may not work in other stores. For more details, refer to Multiple APK Support.
Target Devices		Specifies the target devices on which the APK is allowed to run.
	All Devices	The APK is allowed to run on all Android and Chrome OS devices.
	Phones and Tablets Only	The APK is allowed to run on Android phones and tablets, but not on Chrome OS devices.
	Chrome OS Devices Only	The APK is allowed to run on Chrome OS devices, but not on Android phones or tablets.
Install Location		Specifies application install location on the device (for detailed information, refer to Android Developer documentation on install locations.
	Automatic	Let the operating system decide. User will be able to move the app back and forth.
	Prefer External	Install the application to external storage (SD card) if possible. The operating system doesn’t guarantee it; if not possible, the app will be installed to internal memory.
	Force Internal	Force the application to be installed to internal memory. The user will be unable to move the app to external storage.
Internet Access		Choose whether to always add the networking (INTERNET) permission to the Android App Manifest, even if you are not using any networking APIs. Set to Require by default for development builds.
	Auto	Only add the internet access permission if you are using a networking API.
	Require	Always add the internet access permission.
Write Permission		Choose whether to enable write access to the external storage (such as the SD card) and add a corresponding permission to the Android App Manifest. Set to External(SDCard) by default for development builds.
	Internal	Only grant write permission to internal storage.
	External(SDCard)	Enable write permission to external storage.
Filter Touches When Obscured		Enable this option to discard touches received when another visible window is covering the Unity application. This is to prevent tapjacking.
Sustained Performance Mode		Enable this option to set a predictable and consistent level of device performance over longer periods of time, without thermal throttling. Overall performance might be lower when this setting is enabled. Based on the Android Sustained Performance API.
Maximum Java Heap Size		Set the maximum Java heap size to user for building (in megabytes). Defaults to 4096.
Low Accuracy Location		Enable this option to use low accuracy values with Android location APIs instead.
Chrome OS Input Emulation		Chrome OS’s default behaviour is to convert mouse and touchpad input events into touchscreen input events. Un-check this setting to disable the default behavior.
Android TV Compatibility		Enable this option to mark the application as Android TV compatible.
Android Game		Enable this option to mark the output package (APK) as a game rather than a regular application.
Android Gamepad Support Level		Choose the level of support your application offers for a gamepad. The options are Works with D-Pad, Supports Gamepad, and Requires Gamepad.
Warn about App Bundle size		Enable this option to receive a warning when the size of the Android App Bundle exceeds a certain threshold. This option is selected by default and you can only configure it if you enable the Build App Bundle (Google Play) option in the Build settings.
App Bundle size threshold		Enter a size in Mb. When your App Bundle exceeds this size, Unity will display a warning.
Active Input Handling	Chooses how to handle input from users.
	Input Manager (old)	Use the default Input window.
	Input System (Preview)	Use the newer Input system. The Input System is provided as a preview package for this release. To try a preview of the Input System, install the InputSystem package.
	Both	Use both systems side by side.

Shader Variant Loading

Use these settings to control how much memory shaders use at runtime.

设置	功能
Default chunk size (MB)	Sets the maximum size of compressed shader variant data chunks Unity stores in your built application for all platforms. The default is 16. See Shader loading for more information.
Default chunk count	Sets the default limit on how many decompressed chunks Unity keeps in memory on all platforms. The default is 0, which means there’s no limit.
Override	Enables overriding Default chunk size and Default chunk count for this build target.
Chunk size (MB)	Overrides the value of Default chunk size (MB) on this build target.
Chunk count	Overrides the value of Default chunk count on this build target.

API Compatibility Level

You can choose your mono API compatibility level for all targets. Sometimes a 3rd-party .NET library uses functionality that’s outside of your .NET compatibility level. To understand what’s going on in such cases, and how to best fix it, try following these suggestions:

1. Install ILSpy for Windows.
2. Drag the .NET assemblies for the API compatibility level that you are having issues with into ILSpy. You can find these under Frameworks/Mono/lib/mono/YOURSUBSET/.
3. 拖入第三方程序集。
4. 右键单击第三方程序集并选择 Analyze。
5. 在分析报告中，检查 Depends on 部分。此报告以红色突出显示第三方程序集所依赖的但在您选择的 .NET 兼容性级别中不可用的任何内容。

Script Compilation

属性	描述
Scripting Define Symbols	Sets custom compilation flags. For more details, see Platform dependent compilation.
Additional Compiler Arguments	Adds entries to this list to pass additional arguments to the Roslyn compiler. Use one new entry for each additional argument. To create a new entry, click Add (+). To remove an entry, click Remove (-). When you have added all desired arguments, click Apply to include your additional arguments in future compilations. Click Revert to reset this list to the most recent applied state.
Suppress Common Warnings	Indicates whether to display the C# warnings CS0169 and CS0649.
Allow ‘unsafe’ Code	Enables support for compiling ‘unsafe’ C# code in a pre-defined assembly (for example, Assembly-CSharp.dll). For Assembly Definition Files (.asmdef), click on one of your .asmdef files and enable the option in the Inspector window that appears.
Use Deterministic Compilation	Indicates whether to prevent compilation with the -deterministic C# flag. With this setting enabled, compiled assemblies are byte-for-byte identical each time they are compiled. For more information, see Microsoft’s deterministic compiler option.
Enable Roslyn Analyzers	Indicates whether to compile user-written scripts without Roslyn analyzer DLLs that might be present in your project.

Optimization

Property		Description
Prebake Collision Meshes		Adds collision data to Meshes at build time.
Keep Loaded Shaders Alive		Indicates whether to prevent shaders from being unloaded. For more information, see Shader Loading.
Preloaded Assets		Sets an array of Assets for the player to load on startup. To add new Assets, increase the value of the Size property and then set a reference to the Asset to load in the new Element box that appears.
AOT compilation options		Additional options for Ahead of Time (AOT) compilation. This helps optimize the size of the built iOS player.
Strip Engine Code		Enable this option if you want the Unity Linker tool to remove code for Unity Engine features that your Project doesn’t use. This setting is only available with the IL2CPP scripting backend. Most apps don’t use every available DLL. This option strips out DLLs that your app doesn’t use to reduce the size of the built Player. If your app is using one or more classes that would normally be stripped out under your current settings, Unity displays a debug message when you try to build the app.
Managed Stripping Level		Chooses how aggressively Unity strips unused managed (C#) code. The options are Minimal, Low, Medium, and High. When Unity builds your app, the Unity Linker process can strip unused code from the managed DLLs your Project uses. Stripping code can make the resulting executable significantly smaller, but can sometimes accidentally remove code that’s in use. For more information about these options and bytecode stripping with IL2CPP, see ManagedStrippingLevel.
Enable Internal profiler (Deprecated)		Enable this option to get the profiler data from your device in the Android SDK’s adblogcat output while testing your projects. This is only available in development builds.
Vertex Compression		Sets vertex compression per channel. This affects all the meshes in your project. Typically, Vertex Compression is used to reduce the size of mesh data in memory, reduce file size, and improve GPU performance. For more information on how to configure vertex compression and limitations of this setting, see Compressing mesh data.
Optimize Mesh Data		Enable this option to strip unused vertex attributes from the mesh used in a build. This option reduces the amount of data in the mesh, which can help reduce build size, loading times, and runtime memory usage. Warning: If you have this setting enabled, you should remember to not change material or shader settings at runtime. See PlayerSettings.stripUnusedMeshComponents for more information.
Texture MipMap Stripping		Enables mipmap stripping for all platforms. This strips unused mipmaps from Textures at build time. Unity determines unused mipmaps by comparing the value of the mipmap against the Quality Settings for the current platform. If a mipmap value is excluded from every Quality Setting for the current platform, then Unity strips those mipmaps from the build at build time. If QualitySettings.masterTextureLimit is set to a mipmap value that has been stripped, Unity will set the value to the closest mipmap value that has not been stripped.

Logging

选择在特定上下文中允许的日志记录类型。

• Select your preferred stack trace method by enabling the option that corresponds to each Log Type (Error, Assert, Warning, Log, and Exception) based on the type of logging you require. For example:
  
  • ScriptOnly: Logs only when running scripts.
    
  • Full: Logs all the time.
    
  • None: No logs are ever recorded.
    

See stack trace logging for more information.

Legacy

启用 Clamp BlendShapes (Deprecated) 选项可在 SkinnedMeshRenderers 中钳制混合形状权重的范围。

Publishing Settings

使用 Publishing Settings 可配置 Unity 构建 Android 应用程序的方式。 若要打开 Publishing Settings，请转到 Edit > Project Settings，选择 Player，选择 Android 图标，然后打开 Publishing Settings 面板。

此部分介绍 Publishing Settings 面板的不同部分及其功能。这些资源包括：

• Project Keystore
• Project Key
• Build
• Minify
• Split Application Binary

注意：出于安全原因，Unity 不会保存密钥库或项目密钥密码。

使用 Keystore Manager 窗口可创建、配置和加载密钥和密钥库。 可以从 Keystore Manager 或主 Android 发布面板加载现有密钥库和密钥。如果选择从 Keystore Manager 内部加载这些内容，则 Unity 会自动填充 Project Keystore 和 Project Key 字段。 有关更多信息，请参阅 Keystore Manager 的相关文档。

Project Keystore

密钥库是用于保存签名密钥来实现应用程序安全性的容器。有关详细信息，请参阅 Android 开发者文档：Android 密钥库系统。

使用 Project Keystore 设置可选择用于打开的项目的密钥库。加载密钥库时，Unity 会加载该密钥库中的所有密钥。 若要在打开的项目中加载和使用现有密钥库，请执行以下操作：

1. 启用 Custom Keystore。
2. 打开 Select 下拉列表，选择 Browse，然后从文件系统中选择密钥库。
3. 输入您的密钥库密码。

如果没有现有密钥库，请将 Custom Keystore 保留为禁用状态。

Unity 使用调试密钥库对应用程序进行签名。 调试密钥库是一种工作密钥库。通过它可以对应用程序进行签名并在本地进行测试。但是，应用商店会拒绝以这种方式签名的应用程序。这是因为应用商店无法使用调试密钥库验证应用程序的有效性和所有权。

属性	描述
Custom Keystore	启用 Custom Keystore 可加载和使用现有密钥库。
Select	When Custom Keystore is enabled, use this to select the keystore you want to use. The keystores below the partition in the Select dropdown are stored in a predefined dedicated location. For more details, see Choose the keystore location.
路径	无需输入密钥库路径。Unity 会基于所选择的密钥库提供此路径。
Password	输入密钥库密码以加载所选的密钥库。

Project Key

加载密钥库时，Unity 会加载该密钥库中的所有密钥。使用 Project Key 设置可从该密钥库中选择一个密钥以用作打开的项目的活动密钥。

属性	描述
Alias	选择要用于打开的项目的密钥。
Password	输入密钥密码。

Build

By default, Unity builds your application with the manifest files, Gradle templates and Proguard files provided with the Unity installation. Use the Build section of the Android Publishing Settings to change these.

To use a custom manifest file, Gradle template or Proguard file:

1. 启用相应的复选框。Unity 会在项目中创建一个默认文件，文件位置会出现在复选框下方。
2. 打开新文件并进行更改。
3. 保存对此文件的更改。Unity 下次构建应用程序时会自动使用保存到此文件的更改。

Build 部分中的设置仅适用于当前项目的构建过程。

属性	描述
Custom Main Manifest	Customizable version of the Android LibraryManifest.xml file. This file contains important metadata about your Android application. For more information about the responsibilities of the Main/Unity Library Manifest see Unity Library Manifest.
Custom Unity Launcher Manifest	Customizable version of the Android LauncherManifest.xml file. This file contains important metadata about your Android application’s launcher. For more information about the responsibilities of the Unity Launcher Manifest see Unity Launcher Manifest.
Custom Main Gradle Template	Customizable version of the mainTemplate.gradle file. This file contains information on how to build your Android application as a library. For more information see documentation on Gradle project files.
Custom Launcher Gradle Template	Customizable version of the launcherTemplate.gradle_ file. This file contains instructions on how to build your Android application. For more information see documentation on Gradle project files.
Custom Base Gradle Template	Customizable version of the baseProjectTemplate.gradle file. This file contains configuration that is shared between all other templates and Gradle projects. For more information see documentation on Gradle project files.
Custom Gradle Properties Template	Customizable version of the gradle.properties file. This file contains configuration settings for the Gradle build environment. This includes: • The JVM (Java Virtual Machine) memory configuration. • A property to allow Gradle to build using multiple JVMs. • A property for choosing the tool to do the minification. • A property to not compress native libs when building an app bundle.
Custom Proguard File	Customizable version of the proguard.txt file. This file contains configuration settings for the minification process. If minification removes some Java code which should be kept, you should add a rule to keep that code in this file. For more information see documentation on Minification.

Minify

缩小是一种缩减、混淆和优化应用程序代码的过程。它可以减小代码大小并使代码更难以反汇编。使用 Minify 设置可定义 Unity 应何时以及如何将缩小应用于构建。

在大多数情况下，仅将缩小应用于发布构建（而不是调试构建）是一种很好的做法。这是因为缩小需要时间，可能会使构建速度变慢。由于代码经过优化，它还会使调试更加复杂。

Minify 部分中的设置仅适用于当前项目的构建过程。

属性	描述
Use R8	默认情况下，Unity 使用 Proguard 进行缩小。启用此复选框可改为使用 R8。
Release	如果希望 Unity 在发布构建中缩小应用程序的代码，请启用此复选框。
