Tachiyomi: [Bug] Use Device Auth to gain access crashes

[kennethtran93]

Device information

• Tachiyomi version: Preview r2493
• Android version: 9
• Device: Samsung Galaxy S8
  App version: 0.9.2-2493 (standard, 16fc58bd, 45)
  Android version: 9 (SDK 28)
  Android build ID: PPR1.180610.011.G950WVLS7CTC1
  Device brand: samsung
  Device manufacturer: samsung
  Device name: dreamqltecan
  Device model: SM-G950W
  Device product name: dreamqltevl

Steps to reproduce

1. Open app
2. Press 'use password' on biometric request.

Expected behavior

Show keyboard to type in password to gain access.

Actual behavior

Crashed and restarted. On restart, using biometric successfully returns to previous page /exits app.

Other details

On some occasions, after swiping away the app from the recent screen and reopening the app about a second later, it goes to the library without confirming biometric/password.

I don't think this happened before the last update... Though I'm not sure how the last update may have changed it either.

- implementation 'androidx.biometric:biometric:1.0.1'
+ implementation 'androidx.biometric:biometric:1.1.0-alpha01'

I guess due to this update. I would need the crash logs though.

I've enabled Send crash reports, restarted the app a couple of times until I got the biometric prompt again, then clicked use password. This time, instead of restarting it to re-request biometric for a second time, it just crashed and went back to android launcher.

Unsure if anything got sent to you guys. Let me know where to find the crash logs if any.

It may flow in eventually, but you can also get them manually and post it here using these instructions.

If it helps...

https://issuetracker.google.com/issues/159983244 may be a relevant issue based on what I read in my generated bug report.

Yes, that looks like it. Thanks for saving me the effort for Googling it too. :D

[kennethtran93]

Glad to be of help from one dev (non-android but still a dev) to another.

[kennethtran93]

Any chance the biometric library could be reverted back to pre-alpha for the time being?

[arkon]

Maybe if I need to do a stable release, but otherwise I'll just wait for an update to the library. There's been a fix submitted already.
