My AnimationDrawable object's run method slows down my application, any solutions?

I am writing a basic Android app. I did create an AnimationDrawable object to display my multiple images in my layout and set it. After that, my application started to slow down. And i even tried to work that code block on new thread but it didn't work as i imagined. What did I do wrong? or Is there any solution to that? Thanks in advance.

I'm calling this method on my onCreate() method;

/*
* This method configures the background animation
* */
private void configureAnimation()
animation = new AnimationDrawable();
for (int i = 0; i < bgImage.length; i++)
animation.addFrame(getResources().getDrawable(bgImage[i]), 5000);

animation.setEnterFadeDuration(1000);
animation.setOneShot(false);

linearLayout = (LinearLayout) findViewById(R.id.mLayout);
linearLayout.setBackground(animation);

animation.start();

I think it is safer to call it onResume(), if you start the animation on OnCreate() you will probably get ANR, and you could try this approach:

animation = new AnimationDrawable();
animation.start();
handleAnimation(100,animation);

private void handleAnimation(final int time, final AnimationDrawable animationDrawable)
Handler handler = new Handler();
handler.postDelayed(new Runnable()
@Override
public void run()
for (int i = 0; i < bgImage.length; i++)
animation.addFrame(getResources().getDrawable(bgImage[i]), 5000);

animation.setEnterFadeDuration(1000);
animation.setOneShot(false)
linearLayout = (LinearLayout) findViewById(R.id.mLayout);
linearLayout.setBackground(animation);

, time);



I find my own problem :D. And that was a stupid problem which based on asset plugin that I installed to Android Studio, Android Drawable Importer. Problem is image was so huge to load to HD Screen Emulator so it slowed down the application naturally. When I configure it to normal sizes that as it should be, it solved my problem. I am so sorry to take your time :D. Thank you to everyone who tried to help me out. Happy coding everyone.
