Android splash screen: how to make it centered?

Question

I use a theme-based solution as it described here, for example, to show a splash screen in my application.
Here is my background_launch.xml:

<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="@drawable/launch_image"
android:tileMode="disabled" />

When I have launch_image as png everything is OK. But the app crashes if I use @drawable/layerlist instead of @drawable/launch_image.
layerlist.xml is:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <bitmap
            android:gravity="center"
            android:src="@drawable/launch_image"
            android:tileMode="disabled" >
        </bitmap>
    </item>
</layer-list>

The app crashed with the following log (several lines are skipped):

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.glu.pathlight/com.glu.pathlight.JSFinalNativeActivity}: android.content.res.Resources$NotFoundException: File res/drawable/background_launch.xml from drawable resource ID #0x7f020000

What is wrong in my resources?

Answer 1

Check if you have changed android:src="@drawable/launch_image" to android:src="@drawable/layerlist".

Answer 2

Put this:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
    <bitmap
        android:gravity="center"
        android:src="@drawable/launch_image"
        android:tileMode="disabled" >
    </bitmap>
</item>
</layer-list>

in your background_launch.xml instead of trying to reference a state list in android:src for <bitmap\>

A state list is not a bitmap -- that's what the error's telling you.
