Are you trying to fade to black?
Use this theme in AndroidManifest.xml:
<application
android:theme="@android:style/Theme.Translucent"
Then, you need to write code that modifies this property in
activity_main.xml:
<RelativeLayout android:background="#ee000000"
That property will go from #00000000 (fully transparent) to #ff000000
(opaque black).
