My app still is not showing on the tablets with no SIM card store why?

Question

My app features are:

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

  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="com.android.alarm.permission.SET_ALARM" />
    <uses-permission android:name="android.permission.VIBRATE"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

And I've added:

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

on a phone it shows:

But still it does not appear on the tablets with no SIM card so what's the problem and is there a way to see if it will appear or not before uploading the apk on the store because I can't just upload several apks to test that... thanks.

Answer 1

If you have not added the support Screen tag or compatible-screen tag in your manifest (must not use both together) i would suggest you to add support screen tag in your androidManifest.xml. this is how you can do it.

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

Answer 2

Please add this feature in your Manifest.xml file

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

Reasons for adding this:
The above provided is only a single feature that is not supported by any random Tablet. However, many tablets may not support various features that are provided by the regular handsets:

I hope this helps.

Ok so I've written the command: aapt dump badging project.apk in the command line; but first you should access to the location of the aapt in your command line, then you should add your apk in the location of the aapt, then you write the command in the command line.. and I've viewed the features that are needed by the app and it seems that the android.hardware.location.gps was set to required and since gps is not supported by the tablet that I was searching for the app on, the app didn't show so I sat it to required=false and the app showed on the play store...
