What is the default layout background
The default background color for light theme is: #EEEEEE
Is almost white, but not completely.
It worked for me, hope its work for you.
UPDATE: In new versions you could be looking for #FAFAFA
You can use your theme's default background color by referencing:
?android:colorBackground
To change your background (if this is in fact what you are looking to do):
in styles.xml
<style name = "MyDefaultStyle" parent = "@android:style/Theme"> <item name = "android:windowBackground">@drawable/default_drawable_bg</item></style>
and in your manifest
<application android:name="MyApp" android:theme="@style/MyDefaultStyle" >
