How do you receive outgoing call in broadcastreceiver

Question

I am trying to identify and transfer to an activity after an outgoing call is initiated. I used ACTION_NEW_OUTGOING_CALL in the Intent filter. However how csn I identify that the call is outgoing. I did this for an incoming call (as seen below) but what can I use instead of EXTRA_STATE_RINGING.

public class OutgoingBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
        if (state.equals(TelephonyManager.EXTRA_STATE_RINGING))
        {
            Intent i = new Intent(context, OutgoingCallScreenDisplay.class);
            i.putExtras(intent);
            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(i);
        }
    }
}

public class OutgoingBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
           // If it is to call (outgoing)
           Intent i = new Intent(context, OutgoingCallScreenDisplay.class);
           i.putExtras(intent);
           i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
           context.startActivity(i);
        }
    }
}

ACTION_NEW_OUTGOING_CALL is a constant declare in the Intent class, not in TelephonyManager. When an outgoing call appears, then the system broadcasts an intent with this constant. If you really want to catch an outgoing call by using TelephonyManager then do this:

TelephonyManager tm = (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);   
tm.listen(listener, PhoneStateListener.LISTEN_CALL_STATE);
PhoneStateListener listener = new PhoneStateListener() {
    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
        // TODO Auto-generated method stub

        super.onCallStateChanged(state, incomingNumber);
        switch(state) {
            case TelephonyManager.CALL_STATE_IDLE:
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                if(incomingNumber==null) {
                    //outgoing call
                } else {
                    //incoming call
                }
                break;
            case TelephonyManager.CALL_STATE_RINGING:
                if(incomingNumber==null) {
                    //outgoing call
                } else {
                    //incoming call
                }
                break;
        }
    }
};

Thanks it worked well! But now I am receiving the default screen from the system(see above screenshot) and only after I am getting my customized activity. How can I hide/override the screen with my activity? — user1163234, Mar 05 '12 at 16:17
@ if you want to replace this screen then it's possible only by using telephony AIDL file.. — ρяσѕρєя K, Mar 05 '12 at 16:35
Best example of `ITelephony.aidl` :[mylockforandroid](http://code.google.com/p/mylockforandroid/source/browse/trunk/phone/?r=317) — ρяσѕρєя K, Mar 05 '12 at 16:54
Bad answer as this work also requires adding the broadcast reciever to manifest. — yams, May 11 '22 at 21:23

Detect outgoing phone call event

1. Create OutgoingCallBroadcastReceiver

public class OutgoingCallReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d(OutgoingCallReceiver.class.getSimpleName(), intent.toString());
        Toast.makeText(context, "Outgoing call catched!", Toast.LENGTH_LONG).show();
        //TODO: Handle outgoing call event here
    }
}

2. Register OutgoingCallBroadcastReceiver in AndroidManifest.xml

<receiver android:name=".OutgoingCallReceiver" >
    <intent-filter>
        <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
    </intent-filter>
</receiver>

3. Add permission in AndroidManifest.xml

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

what is the permission for? I managed to fetch the outgoing call without it. — Elad Benda, Dec 06 '14 at 12:55
@Satya It doesn't work for me. Tested in an ASUS Zenfone 2 with Android 6.0.1 — John Alexander Betts, May 21 '17 at 20:06
