I fear that's the problem; me too! On Android 10 (not mine, I don't have it) it seems to work well.

Alberto Michelis · Apr 19, 2021

Ups, there are many, many people using 8, and I have many apps that works ok using fingerprint.

"Easy" to say it, but...

I tried to delete all Android folder but... the operation fails because apparently a file is open and in use (but who knows what! This nice Windows doesn't specify which file

). Only possible attempt: restart the PC (30 MINUTES) and try again!

"See" you later

You can install the new SDK in a different folder. Anyway, I'm able to reproduce the issue with an Android 8 device. I'm checking it.

Yo have the ADB.exe running, open the task manager and delete it

It seems like a bug or a new dependency in the latest version of AndroidX.
The activity must be an AppCompat activity:
1. Main:

B4X:

#AdditionalJar: androidx.biometric:biometric
#Extends: android.support.v7.app.AppCompatActivity
#AdditionalJar: androidx.arch.core:core-runtime
#AdditionalJar: androidx.appcompat:appcompat

2. Manifest:

B4X:

AddPermission(android.permission.USE_BIOMETRIC)
AddPermission(android.permission.USE_FINGERPRINT)
SetApplicationAttribute(android:theme, "@style/MyAppTheme")
CreateResource(values, theme.xml,
<resources>
    <style name="MyAppTheme" parent="Theme.AppCompat.Light">
    </style>
</resources>
)

Tested on Android 8 and 11.

This isn't a problem with B4XPages, right? The code in the Manifest will suffice.

Delete your SDK and download the two components: https://www.b4x.com/b4a.html

Those components, however, contain only platform 30. I guess I can get the 29 from the old folder, right?

You don't need 29.

AppCompat is indeed less recommended with B4XPages. I will post a B4XPages example.

Maybe I also should remove:

CreateResourceFromFile(Macro, Themes.DarkTheme)

from the Manifest.

Why do you need to run the sdk manager? Is the biometric resource missing?
If not then don't do it.

This error will be resolved if you unzip it with 7zip.

Nothing will work unless you follow the instructions: https://www.b4x.com/b4a.html
