I use BroadcastReceiver to intercept incoming call on Android phone as below
tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
Bundle bundle = intent.getExtras();
String number = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
In the "private number" case, I tested on two devices, it shows the number as -1 on HTC Wildfire and -2 on Galaxy S. I checked the android.telephony.PhoneNumberUtils but it could't help me.
Is there a function or a generic way to detect a private number on Android phone? Thanks
