sdlAndroidGetActivity function

Pointer<NativeType> sdlAndroidGetActivity()

Retrieve the Java instance of the Android activity class.

The prototype of the function in SDL's code actually declares a void* return type, even if the implementation returns a jobject. The rationale being that the SDL headers can avoid including jni.h.

The jobject returned by the function is a local reference and must be released by the caller. See the PushLocalFrame() and PopLocalFrame() or DeleteLocalRef() functions of the Java native interface:

https://docs.oracle.com/javase/1.5.0/docs/guide/jni/spec/functions.html

\returns the jobject representing the instance of the Activity class of the Android application, or NULL on error.

\since This function is available since SDL 2.0.0.
