を使用して新しい着信SMSの放送を受信間で定義することができAlarmReceiver.java

public class AlarmReceiver extends BroadcastReceiver { 
    @Override 
    public void onReceive(Context context, Intent intent) { 
     // any action you want to perform will come here 
     Toast.makeText(context, "I'm running", Toast.LENGTH_SHORT).show(); 
    } 
} 

MainActivity.java

public class MainActivity extends Activity { 
    private PendingIntent pendingIntent; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     /* Retrieve a PendingIntent that will perform a broadcast */ 
     Intent alarmIntent = new Intent(MainActivity.this, AlarmReceiver.class); 
     pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, alarmIntent, 0); 

     setAlarm(); 

    } 

    private void setAlarm() { 
     AlarmManager manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE); 
     int interval = 1000 * 60 * 20; 

     /* Set the alarm to start at 8.00 PM */ 
     Calendar calendar = Calendar.getInstance(); 
     calendar.setTimeInMillis(System.currentTimeMillis()); 
     calendar.set(Calendar.HOUR_OF_DAY, 20); 
     calendar.set(Calendar.MINUTE, 00); 

     /* Repeating on every 20 minutes interval */ 
     manager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 
      1000 * 60 * 20, pendingIntent); 

    } 

    public void cancelAlarm() { 
     AlarmManager manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE); 
     manager.cancel(pendingIntent); 
     Toast.makeText(this, "Alarm Canceled", Toast.LENGTH_SHORT).show(); 
    } 

以下のクラスは、彼は装置の再起動後もアラームを発する。

DeviceBootReceiver.java

マニフェストで

public class DeviceBootReceiver extends BroadcastReceiver { 
    @Override 
    public void onReceive(Context context, Intent intent) { 
     if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) { 
      /* Setting the alarm here */ 
      Intent alarmIntent = new Intent(context, AlarmReceiver.class); 
      PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, alarmIntent, 0); 

      AlarmManager manager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); 
      int interval = 8000; 
      manager.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), interval, pendingIntent); 

      Toast.makeText(context, "Alarm Set", Toast.LENGTH_SHORT).show(); 
     } 
    } 
}
