无法更新Symfony - Symfony Installer已更新至最新版本

Question

知道为什么我似乎无法更新Symfony吗？

public class MainActivity extends AppCompatActivity {
    AlarmManager am ;

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

        am = (AlarmManager) getSystemService(ALARM_SERVICE);

        AlarmHATT alarmHATT = new AlarmHATT(getApplicationContext());
        alarmHATT.Alarm();
}
 public class AlarmHATT {
    private Context context;

    public AlarmHATT(Context context) {
        this.context = context;
    }

    public void Alarm() {
        Intent intent = new Intent( context.getApplicationContext(), BroadcastD.class);
        PendingIntent sender = PendingIntent.getBroadcast(MainActivity.this, 0, intent, 0);

        Calendar calendar = Calendar.getInstance();

        calendar.set(calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH),
                calendar.get(Calendar.DATE), 21, 21, 0);

        am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 24*60*60*1000, sender);
    }
}

和FWIW
