[Bug] Android App only runs the first time

[apead]

The app works once. On re-opening the app receive "Microsoft MVP has stopped".

Most likely related to the Auth token, as if I sign out before closing the app, I am able to run the app a second time (and follow the complete login process again).

[jamesmontemagno]

Do you see the "refreshing" token on the screen?

[apead]

Doesn't get that far. Splash Screen -> "Microsoft MVP has stopped".

If there's a "Sign Out" before closing the app, then the app starts fine and goes to "Login" screen.

[apead]

Tried another device and it works on second run and logs in. Android 7.1.1

Issue is repeatable on an Oreo 8.0 device.

[jamesmontemagno]

What device is it?

[apead]

Device is a Nexus 5X

[jamesmontemagno]

Also if you can get a logcat that would be great!

[jamesmontemagno]

Hmmmm and it is full 8.0 or a preview? I will try on an emulator and see if I can reproduce.

[apead]

Official 8.0.0 Security Patch Level: 5 October 2017. Will gather a logcat.

[apead]

Should have a chance to investigate further today.

[jamesmontemagno]

I was unable to reproduce this on the emulator today :(

[apead]

Aah sorry got busy. Let me see what I can find on this device.

[apead]

Looks like it's having a problem parsing the date.

[apead]

Changing from English (UK) to English (US) makes the app start.

[jamesmontemagno]

Interesting.... <3 cools
Good catch!!!

[jamesmontemagno]

Pushing out new build, i think i fixed it.

[apead]

Version 1.1 (65) Nov 3 2017 starts up consistently with English (UK) set.

[jamesmontemagno]
