How to detect outgoing call number in Android Q

Question

I'm unable to get outgoing call number in Android Q.

I've registered receiver in the manifest with this intent filter android.intent.action.NEW_OUTGOING_CALL and in code i'm detecting outgoing phone number like this

@Override
public void onReceive(Context context, Intent intent) {
    if(intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL"))
        String nr = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
}

But i can never get the outgoing call number in Android Q, is there a workaround to get this number differently or since Android Q it is completely impossible to detect outgoing call number?

Edit: It works with previous android versions

You need to add PROCESS_OUTGOING_CALLS permission

Create OutgoingCallReceiver

import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;

public class OutgoingCallReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

            TelephonyManager tm = (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);
            if (tm.getCallState() == TelephonyManager.CALL_STATE_OFFHOOK) {

                String number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);

            }

    }

}

Add required permissions to read outcomming call in AndroidManifest file

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

Request permissions at runtime

if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE)
                != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.PROCESS_OUTGOING_CALLS, Manifest.permission.READ_PHONE_STATE},
                    1);
        }

Add OutgoingCallReceiver in AndroidManifest file

  <receiver
        android:name=".application.services.OutgoingCallReceiver"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.PHONE_STATE" />
        </intent-filter>
    </receiver>

This code will work fine with you, but when you need to upload your application on Google play, It is ok with NEW_OUTGOING_CALL and READ_PHONE_STATE permission but, you will receive a policy notice from playStore as:

Your app manifest requests the Call Log permission group (e.g. PROCESS_OUTGOING_CALLS) It must be actively registered as the default Phone or Assistant handler on the device.

in this case you have 2 solution only if you want to read OutCommingCall Number:

Send declaration form to google declaration form

Or Make your application dialer app
