POAndroid service - keep checking the current time if it match a saved time
text
Body
copied!<p>My Android service has to keep checking if the current time is matching a saved time. I used a service which has a timer that every minute checks if the current time is matching the saved time. If Android goes to sleep mode, he stops checking. I tried WakeLocker for this problem. It works, but it drains my battery.</p> <p>The code I'm currently using is as follow.</p> <pre><code> public class AlarmService extends Service { private static Timer timer = new Timer(); private Context ctx; private WakeLock wakeLock; @Override public int onStartCommand(Intent intent, int flags, int startId) { return Service.START_STICKY; } @Override public IBinder onBind(Intent intent) { return null; } @Override public void onCreate() { Toast.makeText(this, "The new Service was Created", Toast.LENGTH_LONG).show(); super.onCreate(); ctx = this; startService(); /* Wake locker PowerManager mgr = (PowerManager)this.getSystemService(Context.POWER_SERVICE); wakeLock = mgr.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "Wake locker"); wakeLock.acquire(); */ } private void startService() { timer.scheduleAtFixedRate(new mainTask(), 0, 60000); } @Override public void onStart(Intent intent, int startId) { Toast.makeText(this, " Service Started", Toast.LENGTH_LONG).show(); startService(); } @Override public void onDestroy() { Toast.makeText(this, "Service Destroyed", Toast.LENGTH_LONG).show(); } private class mainTask extends TimerTask { public void run() { toastHandler.sendEmptyMessage(0); } } private final Handler toastHandler = new Handler() { @Override public void handleMessage(Message msg) { Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("Europe/Amsterdam")); Date currentLocalTime = cal.getTime(); DateFormat date = new SimpleDateFormat("HH:mm", new Locale("nl", "nl")); date.setTimeZone(TimeZone.getTimeZone("Europe/Amsterdam")); String currenttime = date.format(currentLocalTime); DateFormat date2 = new SimpleDateFormat("EEEE", new Locale("nl", "nl")); date2.setTimeZone(TimeZone.getTimeZone("Europe/Amsterdam")); String currentday = date2.format(currentLocalTime); if(currentday.equals("maandag")) { // "maandag" is dutch for Monday String tijd1 = "16:00"; if(currenttime.equals(tijd1)) { NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(AlarmService.this) .setSmallIcon(R.drawable.ic_launcher) .setContentTitle("Test message") .setAutoCancel(true) .setAutoCancel(true) .setContentText("This is a test message"); Intent resultIntent = new Intent(AlarmService.this, MainActivity.class); TaskStackBuilder stackBuilder = TaskStackBuilder.create(AlarmService.this); stackBuilder.addParentStack(MainActivity.class); stackBuilder.addNextIntent(resultIntent); PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT); mBuilder.setContentIntent(resultPendingIntent); NotificationManager mNotificationManager = (NotificationManager) AlarmService.this.getSystemService(Context.NOTIFICATION_SERVICE); mNotificationManager.notify(1, mBuilder.build()); } } } }; } </code></pre> <p>Does somebody have a solution for this problem, which doesn't drain my battery? So it has to check if the current time is matching the saved time, even when Android is sleeping.</p> <p>Thanks!</p>
