(This is the legacy documentation for SDL2, the previous stable version; SDL3 is the current stable version.)

SDL_AndroidGetActivity

Retrieve the Java instance of the Android activity class.

Header File

Syntax

void * SDL_AndroidGetActivity(void);

Return Value

(void *) Returns the jobject representing the instance of the Activity class of the Android application, or NULL on error.

Remarks

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:

Version

This function is available since SDL 2.0.0.
