The best way to show animations is to save them as PNG and do something like this for animation, put this in your drawable folder:
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="false">
<item android:drawable="@drawable/ant1" android:duration="100" />
<item android:drawable="@drawable/ant2" android:duration="100" />
<item android:drawable="@drawable/ant3" android:duration="100" />
<item android:drawable="@drawable/ant2" android:duration="100" />
</animation-list>
If you want to use vector graphics, you will have to manually switch images. You can watch svg-android , which is a great way to use simple vector images in Android.
