Good morning everyone,

I followed everything by heart in the instructions of the installation of B4A 12.00 and I tried to compile my latest app.

The app does not even open. I tried to jettyfy the libraries as it is suggested sometimes. Nothing. I could find out what might be wrong but I cannot since until now the debugger does not connect in order to see what is wrong - edit: I had to treaten it and it gave me an error but again it started doing the same things. What should I be looking for?

Here are the libraries that it uses for the biometric access:

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

And here is the error

Current solution for me - without crashes at app start:
  • Working only on Java 14 (also for calling SDK manager)
  • Working on newest maven lib files (re-installed via SDK manager)
  • Complete removing ( ! ) of any AppCompatActivity (all references, includes and activity extensions)
  • Only working on this theme: @android:style/Theme.Material
  • But in my case (not for you I guess) I need my own gradient resource (as a gradient background in each activity).
    So I created a new resource "mygradient.xml" in order to use it as a resource style item:
    B4X: 
            SetApplicationAttribute(android:theme, "@style/MyAppTheme")
       CreateResource(values, theme.xml,
        <resources>
            <style name="MyAppTheme" parent="@android:style/Theme.Material">
                <item name="android:windowBackground">@drawable/mygradient</item>
            </style>
        </resources>
)
Not the best solution ... I know ... but this helps me currently to work without any crashes.

By the way: The #MultiDex: True property was already set in my app.


Best regards.
