How to “play” a sequence of photos in Android

I want to be able to display a sequence of photos like a flip book. The latest tool I discovered and am trying to get working is AnimationDrawable. Unfortunately, I cannot figure out how to add photos to the Drawable; when I cast a pointer to AnimationDrawable, I get a NULL.
ImageView splash = findViewById(R.id.splashAnimation);
if ( splash != null ) {
Drawable d = splash.getDrawable();
AnimationDrawable animation = (AnimationDrawable) d;
File directory = getFilesDir();
File files = directory.listFiles();
for (int i = 0; i < files.length; i++) {
Bitmap bitmap = BitmapFactory.decodeFile(files[i].getAbsolutePath());
animation.addFrame(new BitmapDrawable(getResources(), bitmap), 30);
}
}
At line #4, I get a SEGFAULT at address 10. I think the problem is trying to cast Drawable to AnimationDrawable. Is there another way to do this?
