POSilent crash occures in the thread. NotificationManager, timer and threads "magic". Non-trivial problem, as it seems
 

Note that there are some explanatory texts on larger screens.

    <p>I've stucked into the following funny problem:</p> <pre><code>private Object lock=new Object(); public void letsSayMain(){ timer=new Timer(); task=new RequestMessages(); timer.schedule(task, FIRST_DELAY, period*60*1000); //period = 10, FIRST_DELAY=10*1000 } private class RequestMessages extends TimerTask{ public void run() { synchronized(lock){ foo(); Log.d(ApplicationConstants.APPLICATION_CLASS_NAME, "Yay, we've just exited the method!"); } } private void foo(){ . . //Notification initialization . . Log.d(ApplicationConstants.APPLICATION_CLASS_NAME, "We've about to show the notification."); mNotificationManager.notify(z, notificationTransactions); //z is unique int, starting from 1. notificationTransaction - forged notification. Log.d(ApplicationConstants.APPLICATION_CLASS_NAME, "We've shoved the notification."); } }; </code></pre> <p>The output is:</p> <pre><code>07-09 05:23:50.864: DEBUG/AllApp(6919): We've about to show the notification. </code></pre> <p>And that's all.</p> <p>Can someone tell me, what the problem is, and why the execution of the thread code finishes, after call to mNotificationManager.notify() ??? <BR> By the way, the timer is still running, and after another 10 minutes - it will execute that code again. The timer runs the code in it's own thread. I dunno to tell, if the timer thread terminates and then relaunches again in no time, but it seems, that the thread is intact, but executes only top-level stack function (which is just count the timer again).</p> <p>Android shows notification as well.</p> <p>I have that notify() embedded into the for cycle, so it's critical to me - to continue it execution, after the call to mNotificationManager.notify().</p> <p>EDIT1: It really seems like a silent crash:</p> <pre><code>PathClassLoader(ClassLoader).loadClass(String) line: 532 INotificationManager$Stub$Proxy.enqueueNotification(String, int, Notification, int[]) line: 157 NotificationManager.notify(int, Notification) line: 94 . . . </code></pre> <p>And the next step is single line:</p> <pre><code>Timer$TimerImpl.run() line: 294 </code></pre> <p>Before the crash, the <BR><BR> PathClassLoader(ClassLoader).loadClass(String, boolean) line: 563 <BR><BR> executed for the two times repeatedly, but just from the one line of PathClassLoader(ClassLoader).loadClass(String) line: 532. At the second exit - it get's back to loadClass(String), and next moment - it all blows away.</p> <p>Any suggestions - what I should make now?? I've never faced silent crashes before...</p>

    1. COIf I had to guess you probably got a silent runtime exception. Try to debug the thread line by line and see if that occurs. Silent crashes SUCK.

    2. COYeah, it seems it was silent crash. I've edited the post with new info.

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.
