OutOfMemoryError when trying to load multiple frame-by-frame animations one after the other in Android

I have a couple of frame-by-frame animations (animation-list). Loading any one of them to an ImageView is not a problem. The problem occurs when I try to load a different animation in the same ImageView.

private void startAnimation(int anim) {
    mImageView.setImageResource(anim);
    ((AnimationDrawable) mImageView.getDrawable()).start();
}

This was the code that I was using. After getting java.lang.OutOfMemoryError after calling the function more than one time, I added the following code to try and clear the AnimationDrawable and the ImageView.

private void startAnimation(int anim) {
    if (mImageView.getDrawable() != null) { //trying to clear if it's not empty
        if (((AnimationDrawable) mImageView.getDrawable()).isRunning()) {
             ((AnimationDrawable) mImageView.getDrawable()).stop();
             ((AnimationDrawable) mImageView.getDrawable()).selectDrawable(0);
        }
        mImageView.setImageResource(null);
    }
    //starting animation here
    mImageView.setImageResource(anim);
    ((AnimationDrawable) mImageView.getDrawable()).start();
}

Well, this didn't work. I've tried the solutions posted here and here and they also didn't work. I still keep getting OutOfMemoryError.

This is how I call the startAnimation function.

startAnimation(R.drawable.anim1);//works fine
startAnimation(R.drawable.anim2);//OutOfMemoryError
 ...

So, how do I free the memory, and load the animation? Note that I want to do this over and over again.

Solution

  • I finally got it to work by adding mImageView.getDrawable().setVisible(false, true) before starting a new animation.
