###### (This is the legacy documentation for stable SDL2, the current stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current development version.) # SDL_AndroidGetActivity Retrieve the Java instance of the Android activity class. ## Header File Defined in [SDL_system.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_system.h) ## Syntax ```c void * SDL_AndroidGetActivity(void); ``` ## Return Value 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: https://docs.oracle.com/javase/1.5.0/docs/guide/jni/spec/functions.html ## Version This function is available since SDL 2.0.0. ## See Also * [SDL_AndroidGetJNIEnv](SDL_AndroidGetJNIEnv) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction)
