Hey
When I open B4A Sdk Manager and search for biometric I can not find androidx.biometric:biometric
Actually before it the Sdk Manager logger shows this:
B4X:

DataFolder: C:\Users\jafari\AppData\Roaming\B4ASdkManager

In many applications, they make users choose a password in case which touch id ( finger print or biometric authentication or ...) does not work.
1- Is it possible to add something like a button called "using your password" or set an event for "Cancel" button in authentication?
2- Is it possible to change name of "Cancel" button to something else like "Ok"?

I´m trying the BiometricExample and shows in compile:

Convert byte code - optimized dex. Error
Uncaught translation error: com.android.dx.cf.code.SimException: invalid opcode ba (invokedynamic requires --min-sdk-version >= 26)
Uncaught translation error: com.android.dx.cf.code.SimException: invalid opcode ba (invokedynamic requires --min-sdk-version >= 26)
2 errors; aborting

Why?

Hi!
I have just one question: I have an application that at the time was made without the use of B4X Pages. I still haven't been able to convert it. I inserted this function into it and it worked, however, despite the application not using the title bar, when I entered this code the title bar appeared and I could not find how to remove it. Would you help me?
