Exception at startup

[eTaernis]

Hi, this app worked great on my device while I have been on Marshmallow but with my new ROM (Nougat 7.1.1), it does not work. Once I start the app and tries downloading data, I get this error: "Exception: Only the original thread that created a view hierarchy can touch its views."

Please have a look at my logcat:

[Harry-R]

I have the same problem on LineageOS, 14.1 based on Android 7.1.1.

[domoritz]

I don't have time to maintain this app any more. I can merge PRs but won't be able to help otherwise.

[gsauthof]

I can confirm this issue on Android 7.1.2:

The app is still usable after that, though.

That means the default plan is loaded and displayed after the exception popup is accepted.

Fixed and released: https://play.google.com/store/apps/details?id=de.uni_potsdam.hpi.openmensa&hl=en

[azrdev]

@domoritz could you mark the current HEAD with a git tag? The f-droid package will then be updated, it is currently very out of date (and especially experiencing this issue).

[domoritz]

Done
