Question

I am creating an application targeting the tablet users that only in landscape mode. So I created a folder in res named as layout-xlarge-land and put all my layout xml files inside it and kept the layout folder empty. I also set the support screen attributes in manifest file

<supports-screens
    android:anyDensity="true"
    android:largeScreens="true"
    android:xlargeScreens="true"
    android:normalScreens="false"
    android:smallScreens="false" />

I also set all the activity’s orientation to landscape

activity
        android:name=".HomeActivity"
        android:label="@string/title_activity_main" 
        android:screenOrientation="landscape">
    </activity>

when I start my application it doesn’t starts displaying a stopped unexpectedly message.

But when I put all the layout xml files in layout folder my application runs fine.

why this type of behavior? In my view Android system should first look into the layout-xlarge-landfolder to get the UI. If not found then look into ‘layout folder’.
Can someone explain me whether I am right or wrong ?

Answer 1

I got the solution. You have to keep at least one i.e, layout xml file attached to your Launcher Activity inside the layout folder rest of the layout xml files can be kept inside the layout-xlarge-land folder.
