Ok so currently my code looks like below. When I place the call the CustomBroadcastReceiver catches it and the log message is printed out. I can retrieve the telephone number from the bundle. But! I can't get hte CustomPhoneStateListener to work. As you can see I have registered my customPhoneState listener to the receiver but the log message never get's printed out from the CustomPhoneStateListener class. What am I my missing here? Is my thinking correct?

<receiver android:name=".CustomBroadcastReceiver">         <intent-filter>             <action android:name="android.intent.action.PHONE_STATE" />          </intent-filter> </receiver>  </application> <uses-sdk android:minSdkVersion="5" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_CONTACTS" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" />

public class CustomPhoneStateListener extends PhoneStateListener {  private static final String TAG = "CustomPhoneStateListener";  public void onCallStateChange(int state, String incomingNumber){      Log.v(TAG, "WE ARE INSIDE!!!!!!!!!!!");     Log.v(TAG, incomingNumber);      switch(state){         case TelephonyManager.CALL_STATE_RINGING:             Log.d(TAG, "RINGING");             break;     }    }

public class CustomBroadcastReceiver extends BroadcastReceiver {  private static final String TAG = "CustomBroadcastReceiver";  @Override public void onReceive(Context context, Intent intent) {     Log.v(TAG, "WE ARE INSIDE!!!!!!!!!!!");     TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);     CustomPhoneStateListener customPhoneListener = new CustomPhoneStateListener();      telephony.listen(customPhoneListener, PhoneStateListener.LISTEN_CALL_STATE);       Bundle bundle = intent.getExtras();     String phoneNr= bundle.getString("incoming_number");     Log.v(TAG, "phoneNr: "+phoneNr);  } 

Answer 1

Use PhoneStateListener. It has an onCallStateChanged handler; one of the supplied arguments you'll get is a String containing the incoming phone number.

Answer 2

Your overridden method in CustomPhoneStateListener should be called onCallStateChanged() (and not onCallStateChange()).

This would have been spotted by the Java compiler if you would have had the @Override annotation, like you have for onReceive().
