Body
I have a pretty weird problem. I'm setting a notification in my Service in order to launch an Activity. When the Activity launches, an <code>AsyncTask</code> is started. This is how I set up the notification: <pre><code>CharSequence tickerText = getString(R.string.notificationTextUpdates); CharSequence contentText = getString(R.string.app_name); Notification notification = new Notification(icon, tickerText, System.currentTimeMillis()); Intent notificationIntent = new Intent( getApplicationContext(), MyActivity.class); PendingIntent contentIntent = PendingIntent .getActivity(getBaseContext(), 0, notificationIntent, 0); notification.setLatestEventInfo(getApplicationContext(), tickerText, contentText, contentIntent); notifManager.notify(0, notification); </code></pre> If the application is running, everything works, but if it wasn't running before, the AsyncTask's <code>onPostExecute</code> method doesn't get fired. Instead I get the following exception: <blockquote> 09-30 16:07:52.500: WARN/MessageQueue(27729): java.lang.RuntimeException: Handler{4057ec78} sending message to a Handler on a dead thread 09-30 16:07:52.500: WARN/MessageQueue(27729): at android.os.MessageQueue.enqueueMessage(MessageQueue.java:196) 09-30 16:07:52.500: WARN/MessageQueue(27729): at android.os.Handler.sendMessageAtTime(Handler.java:457) 09-30 16:07:52.500: WARN/MessageQueue(27729): at android.os.Handler.sendMessageDelayed(Handler.java:430) 09-30 16:07:52.500: WARN/MessageQueue(27729): at android.os.Handler.sendMessage(Handler.java:367) 09-30 16:07:52.500: WARN/MessageQueue(27729): at android.os.Message.sendToTarget(Message.java:350) 09-30 16:07:52.500: WARN/MessageQueue(27729): at android.os.AsyncTask$3.done(AsyncTask.java:214) 09-30 16:07:52.500: WARN/MessageQueue(27729): at java.util.concurrent.FutureTask$Sync.innerSet(FutureTask.java:253) 09-30 16:07:52.500: WARN/MessageQueue(27729): at java.util.concurrent.FutureTask.set(FutureTask.java:113) 09-30 16:07:52.500: WARN/MessageQueue(27729): at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:311) 09-30 16:07:52.500: WARN/MessageQueue(27729): at java.util.concurrent.FutureTask.run(FutureTask.java:138) 09-30 16:07:52.500: WARN/MessageQueue(27729): at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1088) 09-30 16:07:52.500: WARN/MessageQueue(27729): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:581) </blockquote> Strangely enough, this doesn't happen, when I set up the same notification inside another Activity, so everything works as intended. I'm quiet confused. My Activity runs in SingleTask mode, I also tried SingleTop mode, which basicly didn't change anything.

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.
