I need a local push function. so I made it using alrammanager. but it doesn't

hello. I need a local push function. so I made it using alrammanager.

it does correctly when pure android application using eclipse. but when I created a plugin and load it in unity3d, it doesn't.

I guess unity player can't recognize a BroadcastReceiver. please help me!

following is my code.

[MainActivity] public class MainActivity extends UnityPlayerActivity { public static boolean isInFront = false; private static MainActivity m_MainActivity; private static AlarmManagerBroadcastReceiver m_Alarm;

     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         m_Alarm = new AlarmManagerBroadcastReceiver();
         m_MainActivity = this;
     }
     
     public static void OutputToast()
     {
            final Intent intent = new Intent(m_MainActivity, AlarmManagerBroadcastReceiver.class);
            
            m_MainActivity.runOnUiThread(new Runnable()
            {
                   private AlarmManager alarmManager;
                   private PendingIntent sender;
                   
                   public void run()
                   {                      
                         try
                         {
                            sender = PendingIntent.getBroadcast(m_MainActivity, 0, intent, 0);
                            Toast.makeText(m_MainActivity, "Local Push!", Toast.LENGTH_LONG).show(); 
     
                            Calendar calendar = Calendar.getInstance();
                            calendar.setTimeInMillis(System.currentTimeMillis());
                            calendar.add(Calendar.SECOND, 5);
     
                            alarmManager = (AlarmManager)m_MainActivity.getSystemService(Context.ALARM_SERVICE);
                            alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), sender);
     
                           Toast.makeText(m_MainActivity, "Alarm Start", Toast.LENGTH_SHORT).show();
     
                         }    
                         catch (Exception e)
                         {
                             Log.e("Unity", "ERROR IN CODE:" + e.toString());
                         }
                   }
            });
     }
