Integrate Unity3d view into Android activity

public class UnityPlayerNativeActivity extends NativeActivity { protected UnityPlayer mUnityPlayer; // don't change the name of this variable; referenced from native code

// UnityPlayer.init() should be called before attaching the view to a layout - it will load the native code.
// UnityPlayer.quit() should be the last thing called - it will unload the native code.
protected void onCreate (Bundle savedInstanceState)
{
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    super.onCreate(savedInstanceState);

    getWindow().takeSurface(null);
    setTheme(android.R.style.Theme_NoTitleBar_Fullscreen);
    getWindow().setFormat(PixelFormat.RGB_565);

    mUnityPlayer = new UnityPlayer(this);
    if (mUnityPlayer.getSettings ().getBoolean ("hide_status_bar", true))
        getWindow ().setFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN,
                               WindowManager.LayoutParams.FLAG_FULLSCREEN);

    int glesMode = mUnityPlayer.getSettings().getInt("gles_mode", 1);
    boolean trueColor8888 = false;
    mUnityPlayer.init(glesMode, trueColor8888);

    View playerView = mUnityPlayer.getView();
    setContentView(playerView);
    playerView.requestFocus();
}
protected void onDestroy ()
{
    mUnityPlayer.quit();
    super.onDestroy();
}

// onPause()/onResume() must be sent to UnityPlayer to enable pause and resource recreation on resume.
protected void onPause()
{
    super.onPause();
    mUnityPlayer.pause();
}
protected void onResume()
{
    super.onResume();
    mUnityPlayer.resume();
}
public void onConfigurationChanged(Configuration newConfig)
{
    super.onConfigurationChanged(newConfig);
    mUnityPlayer.configurationChanged(newConfig);
}
public void onWindowFocusChanged(boolean hasFocus)
{
    super.onWindowFocusChanged(hasFocus);
    mUnityPlayer.windowFocusChanged(hasFocus);
}
public boolean dispatchKeyEvent(KeyEvent event)
{
    if (event.getAction() == KeyEvent.ACTION_MULTIPLE)
        return mUnityPlayer.onKeyMultiple(event.getKeyCode(), event.getRepeatCount(), event);
    return super.dispatchKeyEvent(event);
}

}
