For adding a background on your view simply add in the layout xml file

android:background="#000000" or android:background="@drawable/yourdrawable"

where yourdrawable is your image in the drawable folder in your project.

The icon of your app can be changed by replacing the icon.png in the drawable folder or by changing the android:icon="@drawable/yourdrawable in the AndroidManifest.xml
