Hi list!
I'm writing an App to help in the VFR-Navigation.
The App works and help me flying, but sometimes it freezes...
Using the log files, I can see, the App still continue working and sent
display updates command, but the display is freezed. No new data are
displayed and no reaction from user input are received...
I cannot see any exception in my App.
Curiously I cannot reproduce the problem using the emulator, but just
with physical devices and, of course, the problem happens always by
flying, when I don't have any laptop attached to the device and cannot
do any debugging (otherwise I'll crash...).
Not understanding why, but my Tablets "hangs" now at home, too, so I can
start the App from my home and reproduce the problem. The App freezes
and no other actions can be processed...
I connected the Tablet with my PC and started adb logcat.
As I said, no Exception in the App, but I can see some other messages,
that maybe can be related to the problem, such:

and so on... I can send the whole logcat, if needed.
Unfortunately, I didn't found anything useful searching for these
messages. Maybe I'm just dumb...
Can someone help me understanding where is the problem and maybe to
solve it?
As I said, the problem can be reproduced with physical devices (tried
two Tablets and one SmartPhone), but not with the emulator...
Thanks a lot for your help!
