Retrieve incoming call's phone number in Android
android, phone-state-listener, telephonymanager
Solution
Use `PhoneStateListener`. It has an `onCallStateChanged` handler; one of the supplied arguments you'll get is a `String` containing the incoming phone number.
Problem
I would like to retrieve the incoming call's phonenumber and do something with it like the do in http://blog.whitepages.com/2009/02/27/caller-id-by-whitepages-a-new-android-app-that-puts-telemarketers-on-alert/ Could you please help me because I can't find any information about this. Where do i start and how do i get hold of the phonenumber? 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); } ```
