You can get screen buffer size :

void android_main(struct android_app* state) {
  ...

  ANativeWindow* window = state->window;
  ANativeWindow_Buffer buffer;

  // Try lock buffer
  if (ANativeWindow_lock(window, &buffer, 0) < 0)
    return;

  LOGI("buffer info: width = %d height = %d", buffer.width, buffer.height);

  // Unlock buffer
  ANativeWindow_unlockAndPost(window);

  ...
}

I know you can also get screen info through other NDK stuff, but this works!
