Crash: 'Unfortunately, project magnet has stopped'

[isabelrios]

There is something that causes this crash. I can reproduce it 100% with the automated tests (please see video: https://youtu.be/sMK65BxEtLs) but not manually, although I got to see it.

With the automated tests it happens just when disabling bt and opening the app, but manually it is not reproducible following the same steps. It seems to happen when disabling bluetooth and leaving the app in background for a while but so far I see it randomly.

I was wondering if there was something wrong with the automated tests, but once I saw it at least once manually there is something that is causing this. I will investigate further to try to get some clear steps.

@isabelrios can you give us the adb logcat output when the error happens?

I got to reproduce it, here the error I see in the log:

If this is not helpful I can share the full logs file. Thanks @arcturus

@isabelrios interested to know if this still reproduces.

[isabelrios]

@wilsonpage Yes, it still happens, it has to do with the fact that we try to open/refresh the app when bluetooth is disabled (while the app was in background or foreground, if it is closed initially, this does not happen) and somehow the app is not able to show the warning message to enable bluetooth, then the app is closed.

Lets keep issue #242 to track this issue and close this one
