я пытаюсь сделать новый экран входящего вызова в Android,

когда я получаю входящий звонок, мое приложение запускается - но сразу падает, и появляется экран входящего звонка по умолчанию.

Что я делаю неправильно?

мой код:

AndroidManifest.xml:

MyPhoneBroadcastReceiver.java:

package com.example.myfirstapp;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;

public class MyPhoneBroadcastReceiver extends Activity{

    public void onReceive(final Context context, Intent intent) {
            Intent main_intent = new Intent(this, Call.class);
            context.startActivity(main_intent);
    }


}

Call.java:

package com.example.myfirstapp;

import android.app.Activity;
import android.os.Bundle;

public class Call extends Activity{

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    }

}

журнал это:
