Nexus 7 compatibility issue

Question

I have created an Application compatible only for Android Tabs. The Manifest.xml declaration for the App is :

Answer 1

Per the Permissions that Imply Feature Requirements page, android.permission.CALL_PHONE implies android.hardware.telephony, which of course the Nexus 7 does not have. Make sure that telephony is not considered required by adding the following line to your Manifest:

<uses-feature android:name="android.hardware.telephony"
   android:required="false" />

Answer 2

Add below line in your supports-screens Tag,

android:anyDensity="true"

And add uses-feature Tag in manifest,

<uses-feature android:name="android.hardware.telephony" android:required="false"></uses-feature>

Answer 3

I think perhaps the problem is that the App requesting permission to things that don't exist on Nexus 7 Tab.
This permission in your manifest implicitly declares the "android.hardware.telephony" feature. Nexus 7 Tab support this?
Refer to the document: http://developer.android.com/guide/topics/manifest/uses-feature-element.html#market-feature-filtering

<uses-permission android:name="android.permission.CALL_PHONE" />

Try this, keep the permission, but declare the "telephony" feature as false.

<uses-feature android:name="android.hardware.telephony" android:required="false"></uses-feature>

If it's not work, maybe you should change the "normalScreens" setting or "requiresSmallestWidthDp" setting and try again.

With the Open GL feature below,

<uses-feature
android:glEsVersion="0x00020000"
android:required="true" />

This setting will exclude the devices not support OpenGL ES 2.0, but the GPU in Nexus 7 is ULP GeForce, which OpenGL ES Version is 2.0 .
