Hi all This is my first mail to qt interest group. I'm working on an application which tracks and reports user movement over some period of time (2-3 hours)
I have two problems with Android Services. First one is illustrated by this example: https://github.com/frankipl/service-test Application has service which simply counts seconds, it has QTimer with 1 second interval which increments "counter" variable and sends it back to the application. Second counter is inside app and is simply QTime difference between time when service counter was started and "now" time. It seems to me that after a while (minute or so) android service goes to sleep, QTimer doesn't work and doesn't count seconds. To replicate the problem: Install app, start it, reset counter, disconnect the usb cable from the phone, lock the phone, wait a minute or so, and unlock phone, counters will have different readings indicating that Android service wasn't working (counting seconds). However if you keep the usb cable attached to the phone, service is working for a long time - no problem. Second problem is with Qt5positioning. It crashes the service when I try to create default source, this is example: https://github.com/frankipl/service-test-gps In adb logcat there is full output of SIG 11. Service crashes and then is restarted by the operating system and crashes again. I have attached debug from adb logcat. If I use Qtpositioning inside the app, not service it works well. I'm testing this on Qt 5.7 and Android 4.2.2, first problem also on Android 4.4 and Android 6.0 I can report Qt Bug if it is a bug, but first I would like to have some confirmation. Best Regards Marek
