    I am building a wrap for Tapkey.

    Getting help from Erel i was able to come further in this but then i needed to add some more dependencies.

    #AdditionalJar: Tapkey.MobileLib-
    #AdditionalJar: TapKey2.jar
    #AdditionalJar: gson-2.8.5.jar
    #AdditionalJar: Tapkey.SharedLib-
    #AdditionalJar: auth0-1.15.1.aar
    #AdditionalJar: okhttp-2.7.5.jar
    #AdditionalJar: okio-1.11.0.jar
    #AdditionalJar: androidx.core:core
    #AdditionalJar: androidx.lifecycle:lifecycle-viewmodel
    I now ran into new errors.

    As far i can see it is because the Tapkey library is most probably using the Androidx Support-Libraries. Due to this i need to use them too (i read something similar in internet). There is also a guide for the Migration:

    But i´m lost here as i don´t know what to do here to fix the problem.

    Seems like you need to remove the old Android Support libraries. Create a new project with only these #AdditionalJars. Does it compile?

    Can you tell me what i have to use in ExcludeClasses if it does not compile in a new project? So i would know which to exclude and test it then.

    As of now i do not have the time anymore; need to go to work now. But i´ll try this evening and give updateinfo.

    ExcludeClasses won't be enough here. You need to remove the dependencies of the standard Android support libraries.

    You mean the artifacts in SDKPATH\extra\b4a_remote\ and also the lines in the installed-components.txt?

    It does not work. Even in the Testproject i get this error.

    I tried to setup a new app two times.

    It ends with this error:

    What is your suggestion? How can i remove the dependencies to the old supportlibrary?

    i always added the tapkey code too.

    I now setup a third blank project. I now added only the #addditionaljar lines and the manifest.

    It compiles fine without an Error.

    I still don't understand which libraries cause the old Android Support library to be added. You need to find it.

    Probably it is this one which is referenced by Tapkey

    I downloaded the source, checked where any Resources are used, replaced all support to androidxsupport (Mappings), found out that it is mostly the WebAuthActivity which was adding the Supportlibrary due to AppCompat activity and some more.

    In the code-flow one need to define the Webauth activity in Manifest and Tapkey will redirect to this activity.
    While going over the source and editing it i realized that the problematic Activity is called due to an Manifestentry. I thinked over this and saw that i - probably - can easily replace this activity with an B4A Activity.

    Finally i decided to remove the Auth0 WebAuthActivity and i´ll create an B4A Activity for the WebAuth (using Webview). Here i have all control over the webview that i need.
    In Manifest i´ll set the webauth activity to be the b4a activity. Hope to get further this weekend. Today i´ll get the Test-Hardware provided by my customer.

    I´ll update this thread - or maybe create a new one if i face another problem ;-).
    Honestly i do have another problem related to references to okhttp inside the library. I´ll create a new thread for this.
