For cross-platform Projects, use the UNITY_ANDROID define directive to conditionally compile Android-specific C# code. For more information, refer to Platform dependent compilation.
Applications can access most features of an Android device through the Input and Handheld classes. For more information, see:
To trigger a vibration, call Handheld.Vibrate. Devices without vibration hardware ignore this call.
Mobile operating systems have built-in activity indicators your application can use during slow operations. For more information, refer to Handheld.StartActivityIndicator.
To access device-specific properties, use these APIs:
| 脚本 | 设备属性 |
|---|---|
| SystemInfo.deviceUniqueIdentifier | 始终返回 ANDROID_ID 的 md5。有关更多信息，请参阅 Android 开发者文档的 ANDROID_ID 部分。 |
| SystemInfo.deviceName | 返回设备名称。对于 Android 设备，Unity 会尝试从安全系统设置中读取 device_name 和 bluetooth_name。如果这些字符串没有值，Unity 将返回 <unknown>。 |
| SystemInfo.deviceModel | 返回设备型号。这通常包括制造商名称和型号（例如“LGE Nexus 5”或“SAMSUNG-SM-G900A”）。 |
| SystemInfo.operatingSystem | 返回操作系统名称和版本。 |
