MainActivity

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

        initialize();
    }

    private void initialize() {
//        Calendar cal = Calendar.getInstance();
//        cal.set(Calendar.MONTH, 5);
//        cal.set(Calendar.YEAR, 2015);
//        cal.set(Calendar.DAY_OF_MONTH, 30);
//
//        cal.set(Calendar.HOUR_OF_DAY, 1);
//        cal.set(Calendar.MINUTE, 12);

        cal.set(2015, 05, 30, 1, 22);

        Intent intent = new Intent(this, AlarmReceived.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
        AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

    public void onReceive(Context context, Intent intent) {

        Toast.makeText(context,"Yess",Toast.LENGTH_LONG).show();

    }

I solved it. My code was working fine but it was problem of the OS. In java or android the Calender month starts from 0 so here January wont be 1 it will be 0 and so on. So to solve this just do

Month-1

to get the current month
