Ich versuche, Toast anzuzeigen, nachdem ich einen Anruf erhalten habe. Ich habe alle notwendigen Dinge implementiert, um den Rundfunkempfänger zu registrieren, aber es wird kein Toast angezeigt. Ich versuche, dieses Programm auf dem Marshmallow-Gerät auszuführen.

MyCallReceiver.java -

package com.suhas.callreceiver;

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 MyCallReceiver extends BroadcastReceiver {

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

    if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_RINGING)) {
        // This code will execute when the phone has an incoming call

        // get the phone number
        String incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
        Toast.makeText(context, "Call from:" +incomingNumber, Toast.LENGTH_LONG).show();
        Log.d("MyTrack call", "call receive");

    } else if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
            TelephonyManager.EXTRA_STATE_IDLE))
    {
        Toast.makeText(context, "Detected call hangup event", Toast.LENGTH_LONG).show();
    }
    else if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
            TelephonyManager.EXTRA_STATE_OFFHOOK)) {
        // This code will execute when the call is disconnected

    }
}
}
