For example
in main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/nameOfYourLocalFile"
android:orientation="vertical" >
</LinearLayout>
Just put your nameOfYourLocalFile.png
to drawable
directory.
Hope its help.
