Mein Empfänger empfängt keinen Alarmmanager

Question

Ich versuche, eine Benachrichtigung zu einem bestimmten Zeitpunkt zu senden, ich suche online eine Lösung, aber Code wird nicht funktionieren.

Ich Benutzer Alarm Manager mit BroadcastReceiver, aber BroadcastReceiver erhalten nie meinen Alarm. Warum?

Manifest.xml:

<receiver android:name=".AlarmReceiver"/> 
<uses-permission android:name="android.permission.WAKE_LOCK" /> 

MainActivity.class:

... 
    AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE); 
    Intent i = new Intent(MainActivity.this, AlarmReceiver.class); 
    PendingIntent pi = PendingIntent.getBroadcast(MainActivity.this, 0, i, 0); 

    Calendar c = Calendar.getInstance(); 
    c.set(Calendar.HOUR_OF_DAY, hour);  // hour is an int selected from user 
    c.set(Calendar.MINUTE, minute);   // minute is an int selected from user 
    am.set(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), pi); 

Mein Receiver:

public class AlarmReceiver extends BroadcastReceiver { 


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


    Log.d("ALARM RECEIVER", "Alarm received"); 

    // do stuff... 
    } 
}
