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);

}

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().

Answer 3

The above answers are out-od-dated now. There are valid for Android 7 and lower.

For android 9 and higher you have to add another permission in the Androidmanifest.xml with the permission

<uses-permission android:name="android.permission.READ_CALL_LOG"/>

without the phone number will be null. For Android 8 I am not sure.

PhoneStateReciever.java

    package com.incomingcalls;
    import android.content.BroadcastReceiver;
    import android.content.Context;
    import android.content.Intent;
    import android.telephony.TelephonyManager;
    import android.util.Log;
    import android.widget.Toast;


    public class PhoneStateReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {

        try {
            System.out.println("Receiver start");
            String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
            String incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
            Log.e("Incoming Number", "Number is ," + incomingNumber);
            Log.e("State", "State is ," + state);
            if(state.equals(TelephonyManager.EXTRA_STATE_RINGING)){
                Toast.makeText(context,"Incoming Call State",Toast.LENGTH_SHORT).show();
                Toast.makeText(context,"Ringing State Number is -"+incomingNumber,Toast.LENGTH_SHORT).show();


            }
            if ((state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK))){
                Toast.makeText(context,"Call Received State",Toast.LENGTH_SHORT).show();
            }
            if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)){
                Toast.makeText(context,"Call Idle State",Toast.LENGTH_SHORT).show();
            }
        }
        catch (Exception e){
            e.printStackTrace();
        }

    }
}
