Splash Screen with 2 Images in Android

Question

I have a Splash Screen set up in my Android app that runs the length of a network call and then switches to the main (maps) activity.

I am wondering if I can use a 2nd image in this Splash Screen as a way to list sponsors. The splash I have now lasts up to 5 or 6 seconds so I would rather not add a 2nd Splash activity.

What I am hoping is that I can just add a second image to the current activity. The first one for 2 seconds and the second for the remainder of the network call.

here is part my code. Please let me know if this is possible to add to the existing code. Thanks!

   

   

    // Splash screen timer
    private static int SPLASH_TIME_OUT = 1000;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);
        wmbPreference = PreferenceManager.getDefaultSharedPreferences(this);
        ConnectivityManager conectivtyManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        if (conectivtyManager.getActiveNetworkInfo() != null
                && conectivtyManager.getActiveNetworkInfo().isAvailable()
                && conectivtyManager.getActiveNetworkInfo().isConnected()) {
            isConnected = true;
        } else {
            isConnected= false;
        }

        if(isConnected)
            new LoadAllVendors().execute();
        else
        {
            final Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {
                    Intent intent1 = new Intent(SplashScreen.this, ShoppingListActivity.class);
                    finish();
                    startActivity(intent1);

I would simply add another handler here

Handler mHandler;
...

if(isConnected){
     new LoadAllVendors().execute();
     mHandler = new Handler();
     mHandler.postDelayed(new Runnable() {
            @Override
            public void run() {
            //set the second image
            }
        }, 2000);
}

protected void onDestroy(){
   ...
   // make sure to clean up handlers when activity is destroyed
   if (mHandler != null)
     mHandler.removeCallbacksAndMessages(null);       
}

Also you don't need to do runOnUiThread in onPostExecute block. It's already running on UI thread so you should remove it.
