App crashes upon start.

[OlivierS1]

Actual behaviour

• Tell us what happens.
  Since update to what seems to be NC 3.7.0.RC2, NC is crashing upon start. I have no way to connect to my servers using the app, and update from my phone obviously cannot be performed.
  I wish there was a way to revert to a state prior to this update.
  In a nutshell, I am in dead water.
  I am thinking, that maybe I should pull out of the Beta testing program if no fall back options is made available.

Expected behaviour

• Tell us what should happen.It should work. Nothing more simple than that.

Steps to reproduce

1. Start NC.

1. What happens if you reinstall the app from scratch? 2. Can you pls provide a stacktrace? Nextcloud staff is off for a long weekend (I guess judging from public holiday calendar), but I could maybe give it a look in the meantime.

Reinstalled my Nextcloud app RC. No help.
Crashing after drawing and after iris check.

Downloaded/installed 3.6.2 from F-Droid. It's working. Now I can go back to beta in the Play Store when I want to.

Same for NC 3.7.0 RC3 - crashes upon start.

@Wikinaut since there haven't been any logcats yet, are you able to provide one (and the corresponding stack trace) of the crash?

[Wikinaut]

@AndyScherzinger Sorry, I cannot provide you with logs. It happens on the above mentioned devices.

@AndyScherzinger, can you get ACRA PR against NC 3.7.0 RC3? That would allow users to actually generate a stack trace for us. No need to "release" - just QA build should do the trick.

[ezaquarii]

@emresaracoglu are you able to use ADB to dump the stack trace?

[emresaracoglu]

@ezaquarii Unfortunately, this is currently impossible. I haven't installed Android Studio after the format.

@ezaquarii sure thing: #4154 should do the trick

[ezaquarii]

@AndyScherzinger , splendid!

@emresaracoglu can you try to reproduce this problem with a build #4154 ?

There is a QR code with/and URL with a test APK - if you install it, it should launch an email composer with stacktrace when the app crashes. This way we can get to the bottom of the issue.
