AndroidJavaRunnable

Description

AndroidJavaRunnable is the Unity representation of a java.lang.Runnable object.

Note that this is a delegate. As such, a new java.lang.reflect.Proxy object is created every time it is passed as an argument to Java. This means that passing a variable of AndroidJavaRunnable type to Java multiple times results in a new Java object each time with different hash code values. It also means that calling equals() on the Java object created as a representation of an AndroidJavaRunnable variable always returns false, even when compared to itself.
