    I'm happy to release B4A v9.30 BETA. This update adds support for the new AndroidX SDK.


    AndroidX SDK replaces the Android Support Library SDK. Android Support Library is no longer maintained and new resources such as the latest versions of Firebase libraries depend on AndroidX.

    With B4A v9.30 you can continue to use the old Android Support Library or switch to AndroidX. Switching to AndroidX is simple: https://www.b4x.com/android/forum/threads/androidx-sdk.107236/

    • Support for AndroidX SDK.
    • Jetifier tool that creates AndroidX versions of libraries. Note that this step isn't needed for most libraries.


    • Auto bookmarks feature:

      • Recent code positions and designer layouts appear as tabs in the window title.
      • The IDE decides on the list of tabs based on several factors (recency, modifications and others).
      • The list is saved together with the project and restored when the project is loaded.
    • Ctrl + Click on layout files from the code:

    • B4A Sdk Manager v3.50 is included. It supports AndroidX resources.
    • Issue with BaseFolder in command line builder fixed.
    • Latest versions of internal libraries are included. TabStripViewPager is an internal library now.
    • Bug fixes and other minor improvements.

    Developers who are eligible for a free upgrade will receive an email with upgrade instructions.
    Remember that this is a beta version!

    The real test is to open B4A Sdk Manager and update the recommended items. It will show a message about AndroidX and you will then compile your app with AndroidX SDK.

    You can always go back to the old SDK by downloading the ready to run SDK.

    That's the first things that I did Erel after reading above that B4A Sdk Manager being updated to V3.50.

    The amount of preselected items were phenomenal, there are loads of them. I've now assembled 5 of my clients packages with absolutely no issues whatsoever.

    Btw I also ran the Jetifier tool, there's just 2 libs that it didn't appear to like too much (or whatever).

    Thanks again Erel...

    Work Perfect !!!
    Great job, ... thank you very much

    7 years ago, I decided to try B4A, it was one of the best decisions made in my life.
    A pleasure to work with a tool like B4A, and a human support from EREL and all the collaborators of this forum.

    Greetings to all

    I saw it as well (AcceleratedSurface and another one). The error happens in the Android SDK tool. Most libraries don't need to be "jetified" anyway so you can ignore those errors.

    There was a bug in beta #1 related to Android Support Library and usages of #Extends attribute. Beta #2 was uploaded. It fixes this issue.

    Which library causes this error? Where is the relevant code?

    Make sure that the library is not in the internal libraries folder as it will not be jetified.
