我的BroadcastReceiver不会打电话

我在致电我的BroadcastReceiver时遇到问题。我不知道问题在哪里。这是我的代码Myalarm.class，它会自动调用BroadcastReceiver（AlarmReceiver）。我在广播中做了一些标记，看他是否打过电话。

MyAlarm.class

public class MyAlarm extends SherlockFragmentActivity implements OnClickListener {
    TextView textAlarmPrompt;
    public static final int NOTIFICATION_ID = 42;
    private String notificationTitle;
    TimePickerDialog timePickerDialog;
    final static int RQS_1 = 1;
    String ID_Alerte;
    long alarm_GPS;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.myalarm);
        ((Button)this.findViewById(R.id.annuler)).setOnClickListener(this);
        Intent i = getIntent();
        Bundle myBundle= i.getExtras();
        alarm_GPS = myBundle.getLong("alarm_gps");
        ID_Alerte = myBundle.getString("id_alerte"); 
        //  openTimePickerDialog(false);

        ///////////// call AlarmReceiver//////////////:
        AlarmManager am=(AlarmManager)this.getSystemService(Context.ALARM_SERVICE);
        Intent intentlocalisation = new Intent(this,AlarmReceiver.class);
        //put data to BroadcastReceiver 
        intentlocalisation.putExtra("id_alerte", ID_Alerte);
        PendingIntent pi = PendingIntent.getBroadcast(this, 0, intentlocalisation, 0);
        am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()+3000, alarm_GPS , pi); 

    }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        switch(v.getId()){
        case R.id.annuler:
        /////////   Alarm SMS cancel (AlarmReceiver)  //////////
            Intent intent_stopsms = new Intent(this, AlarmReceiver.class);
            PendingIntent sendersms = PendingIntent.getBroadcast(getBaseContext(), RQS_1, intent_stopsms, 0);
            AlarmManager alarmManagersms = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
            alarmManagersms.cancel(sendersms);
            Toast.makeText(this, "Cancelled alarm sms", Toast.LENGTH_SHORT).show();

            Intent adv=new Intent(MyAlarm.this,
                    Home.class);
            startActivity(adv);
            finish();
            break;
        }
    }
}

这是我的AlarmReceiver：

public class AlarmReceiver extends BroadcastReceiver {
    String ID_Alerte;
    @Override
    public void onReceive(Context arg0, Intent arg1) {
        arg0.stopService(new Intent(arg0, MyService.class));
        ///////////////////////////
        Log.i("Alarm Receiver","My receive is shown up");
        ID_Alerte=arg1.getStringExtra("id_alerte");
        Toast.makeText(arg0, "Alarm received!id_alerte=" +ID_Alerte , Toast.LENGTH_LONG).show();
        //////////////////////////////////
        Intent serviceIntent = new Intent(arg0,MyService.class);
        serviceIntent.putExtra("id_alerte", ID_Alerte);
        arg0.startService(serviceIntent);
    }
}

这是我的Manifest.xml
