I'm trying to perform frame by frame animation in android. For this task I created an xml file called "anim.xml" like this:

    <?xml version="1.0" encoding="utf-8"?>
    <animation-list xmlns:android="http://schemas.android.com/apk/res/android"
    android:oneshot="false">
    <item android:drawable="@drawable/square0" android:duration="100" />
    <item android:drawable="@drawable/square1" android:duration="100" />
    <item android:drawable="@drawable/square2" android:duration="100" />
    <item android:drawable="@drawable/square3" android:duration="100" />
    <item android:drawable="@drawable/square4" android:duration="100" />
    <item android:drawable="@drawable/square5" android:duration="100" />
    </animation-list>

Then at a frame layout that I have defined, I tried to set it as background and start it at onCreate like this:

    FrameLayout imgView = (FrameLayout)findViewById(R.id.frameLayout1);
    imgView.setBackgroundResource(R.drawable.anim);
    AnimationDrawable anim = (AnimationDrawable) imgView.getBackground();
    anim.start();

What I'm experiencing is the first frame only, but what I'm going for is an animation of squares to be on a loop. Do you have any opinions regarding what I have done wrong ?

Cheers.

I've experience issues before when trying to get animations to start in the onCreate method. Try repalcing your last line with something like:

imgView.post(new Runnable()
    {
        @Override
        public void run()
        {
            anim.start();
        }
    });

This will essentialy make you animation start after onCreate has executed.
