As recently announced on the Google I/O 2013, there has been an update to Google Play filtering strategy of Android applications. Applications not specifically identified as designed for tablets will not show in search results in Google Play.
To achieve this the following properties should be added to the Manifest file:
<uses-sdk android:minSdkVersion="9" android:targetSdkVersion="15" />
<uses-feature android:name="android.hardware.telephony" android:required="false" />
According to the Google Play Filter strategy the individual screen sizes shouldn’t be necessary as the default values should then be true. But since Google Play optimization recommends setting the largeScreens and xlargeScreens (from SDK-version 9 and upward) it might as well be done.
