To ensure that you can distribute your app to a broad range of tablets, your app should declare support for tablet screen sizes in its manifest file, as follows:
A <supports-screens> element, if declared, must not specify android:largeScreens="false" or android:xlargeScreens="false".
For apps targeting minSdkVersion value less than 13, a <supports-screens> element must be declared with both android:largeScreens="true" and android:xlargeScreens="true".
If the app declares a <compatible-screens> element in the manifest, the element should include attributes that specify all of the size and density combinations for tablet screens that the app supports. Note that, if possible, you should avoid using the <compatible-screens> element in your app.
