Alarmmanager Doesn`t Start Broadcastreceiver

I am trying to use BroadcastReceiver and AlarmManager to set a one-shot alarm. I have no idea why isn`t it working. What am I doing wrong? I have no exceptions, no logs about, no s

Solution 1:

try like this: it will fire alarm after 30 second.

publicclassTestAlarmManagerextendsActivity{

    @OverrideprotectedvoidonCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        setAlarm(getApplicationContext());

    }
    publicvoidsetAlarm(Context mContext) {

        Intentintent=newIntent(this, AlarmReceiver.class);  
        PendingIntentpendingIntent= PendingIntent.getBroadcast(  
                                      this.getApplicationContext(), 234324243, intent, 0);  
        AlarmManageralarmManager= (AlarmManager) getSystemService(ALARM_SERVICE);  
        alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()  
                                      + (30 * 1000), pendingIntent);  
        Toast.makeText(this, "Alarm set in " + 30 + " seconds",Toast.LENGTH_LONG).show();  
    }

}

AlarmReceiver.java

publicclassAlarmReceiverextendsBroadcastReceiver {

    @OverridepublicvoidonReceive(Context context, Intent arg1) {
        Log.e("alarm","got into alarm receiver");
        Toast.makeText(context, "Alarm Started..", Toast.LENGTH_LONG).show();  
    }

}
