Answer 1

First of all get Clear that, Not all Android tablet supports telephony manager . but some do,

Actually telephony is an "umbrella feature" , where the tablet may support some sub-features.

EDIT:

1. Specify a uses-feature node for every API feature used by your app. This forces you to think about what your app uses, allowing you to:

2. Decide which features are necessary for your app to be useful and mark those featured with the attribute required=true . This lets Market hide your app from any device that doesn't support the hardware features your app requires.

Something like,

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

Answer 2

TelephonyManager telephonyManager1 = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
           if(telephonyManager1.getPhoneType()==TelephonyManager.PHONE_TYPE_NONE)
{
  //coming here if Tablet 
}
else{
  //coming here if phone
}
