问题
I am getting multiple reports from users that they can't get GPS or location services in my app until they restart their phone, and then everything works no problem.
I only get a limited sample of android users complaints, from the set of users that use my apps but it seems shockingly similar to this issue:
https://code.google.com/p/android/issues/detail?id=39745
Google OTA updates rolled out to some additional carriers last week. Looking through my code changes over the last several months, I haven't changed any GPS/positioning stuff except in cases where I had to use the new google maps, but I can't tell if my particular user complaints are coming from a very old version or an upgrade from a very recent version or whatever version.
It appears to be related to Android 4.2 but I can't confirm that either, except the similarity of users restarting their phone and everything magically solves itself. I don't consider this a valid troubleshooting option though for my users.
Basically wondering if anyone else has solved this in code, and also putting it here in case other developers can relate to this
