Question

I have a purely native Android NDK app. The main loop is in

 android_main

as provided by the android_native_app_glue.h.

I need to render something in a separate thread, so via android_main I tried:

 pthread_t thread1;
 pthread_create(&thread1, NULL, renderstuff, NULL);

void *renderstuff( void *ptr )
{
  // some opnegl es draw calls
}

However this does not render anything. If I perform the same draw calls from within android_main (but without creating a new thread), it renders fine :S

Answer 1

I ended up reworking things to ensure that only a single thread performs the rendering.
