Instant app crash on opening, SQLiteException: file is not a database

• Bug is not already reported in another issue

Describe the bug

I click on the app icon/select “open app” in exposure settings to open the app. Main activity is shortly visible, then app crashes. No error message displayed (This differs from other bug reports). After a few tries Android suggests to uninstall the App.

Expected behaviour

No crash expected. In case it happened the app could recover by re-initializing the missing/corrupt database.

Steps to reproduce the issue

Simply open the app. The app worked fine since it was released and got auto-updated each time new releases had been available. No specific action required to break it.

Technical details

• Mobile device: ZTE Axon 9 Pro
• Android version: 9, Security Patch level July 1, 2020
• App Version: 1.3.1
• Prioritized Background Activity: On
• Battery Power saver options turned off, “Adaptive Battery” off, CWA set as “Don’t optimize”

Possible Fix

unclear. Will try re-installing the app

@heinezen Thanks for coming back on this issue. After a closer examination of the timeline it turned out that it failed actually with 1.3.0, but then app updated on same day to 1.5.0 and I got a different error for probably the same issue in #1469. I deleted CWA data. Now at 1.5.1 and it has not crashed since. As it did run for months previously without an issue nothing of statistical significance.

As the fix for the supposed root cause is in and with 1.5.1 the remaining implementation issue is fixed as well, I will close this issue also.

@KommX

It’s too bad, that I’ll have to reset the app. Hopefully, the test result will be negative anyways, so that no possibility to warn other people will be lost.

Even if you reset the CWA data in the app, as long as you don’t uninstall/reinstall it, your keys will still be saved in the Google Exposure Notification Framework (ENF). So if your result turns out positive, you can still request a Tele-tan from the hotline and share your keys to warn others.
