    <p>I am working on a background service that for a period of time poll to a server something. The point is that: I have an IntentService (called NotificationsService) which calls another service, but the response of this request does'nt get back. And in the logcat appears:</p> <pre><code>06-19 05:12:00.151: W/MessageQueue(6436): Handler (android.os.Handler) {416659f0} sending message to a Handler on a dead thread 06-19 05:12:00.151: W/MessageQueue(6436): java.lang.RuntimeException: Handler (android.os.Handler) {416659f0} sending message to a Handler on a dead thread 06-19 05:12:00.151: W/MessageQueue(6436): at android.os.MessageQueue.enqueueMessage(MessageQueue.java:196) 06-19 05:12:00.151: W/MessageQueue(6436): at android.os.Handler.sendMessageAtTime(Handler.java:473) 06-19 05:12:00.151: W/MessageQueue(6436): at android.os.Handler.sendMessageDelayed(Handler.java:446) 06-19 05:12:00.151: W/MessageQueue(6436): at android.os.Handler.post(Handler.java:263) 06-19 05:12:00.151: W/MessageQueue(6436): at android.os.ResultReceiver$MyResultReceiver.send(ResultReceiver.java:50) </code></pre> <p>I looked here problems similar but I got confused (I'm not using any AsyncTask, and I've looked for CommonsWare code wakefullIntent but i didn't understand it).</p> <p>Here it's the code for NotificationsService.java</p> <pre><code>public class NotificationsService extends IntentService { private static int TIME_INTERVAL_MILIS=90000; private static final int REFRESH=10; private NotificationManager noteManager; private static List&lt;FlightStatusNote&gt; flights= new ArrayList&lt;FlightStatusNote&gt;(); public NotificationsService(){ super("NotificationsService"); } @Override public void onCreate(){ Log.d("notificationsSservice","onCreate"); super.onCreate(); noteManager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE); } @Override protected void onHandleIntent(Intent intent) { Log.d("NotificationsService","Me llamaron"); Log.d("NotificationsService", "intervalo:"+NotificationsService.TIME_INTERVAL_MILIS); Log.d("NotificationsService","Itero por cada vuelo registrado para notificar"); for(FlightStatusNote f: flights){ FlightStatus fly=f.getFlight(); Log.d("NotificationsService","Vuelo id:"+fly.getAirlineId()+fly.getNumberFlight()); Intent intentaux=new Intent(Intent.ACTION_SYNC,null,getBaseContext(),FlightStatusService.class); intentaux.putExtra("airlineFlight", fly.getAirlineId()); intentaux.putExtra("numberFlight",fly.getNumberFlight() ); intentaux.putExtra("receiver", new ResultReceiver(new Handler()) { @Override protected void onReceiveResult(int resultCode, Bundle resultData) { super.onReceiveResult(resultCode, resultData); Log.d("notificationsService","response received"); if (resultCode == FlightStatusService.STATUS_OK) { List&lt;FlightStatus&gt; fly = (List&lt;FlightStatus&gt;)resultData.getSerializable("return"); for(FlightStatus f: fly){ int indexNote=flights.indexOf(new FlightStatusNote(f,null)); FlightStatusNote fsNote=flights.get(indexNote); List&lt;String&gt; changes=fsNote.hasChanged(f); if(changes==null){ Log.d("notificationsService","changes is null"); } else{ Log.d("notficationsService", "comething changed"); createNotification(f, changes); } } } } }); startService(intentaux); } AlarmManager alarmMgr = (AlarmManager) getBaseContext().getSystemService(Context.ALARM_SERVICE); PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), 0, new Intent(getBaseContext(), DealAlarmReceiver.class), 0); alarmMgr.set(AlarmManager.RTC, System.currentTimeMillis()+NotificationsService.TIME_INTERVAL_MILIS, pendingIntent); } } </code></pre> <p>If anyone can help me, I would appreciate it a lot! Cheers!</p> <p>Edit: I think the problem is that the Log "response received" it doesn't appear.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
