epiCode Active Member Licensed User Sep 2, 2021 #1 Scenario: All SDK etc are installed as per instructions from B4A installation and work fine. Then I open an example which gives following error on compilation: Legacy-Support-v4 required Then I install it using B4A SDK Manager The error changes to androidx.activity required It keeps giving maven artifacts not found one after the other after installing like 30+ artifacts it finally moves on and... the program fails to compile with 2 errors: Uncaught translation error: com.android.dx.cf.code.SimException: invalid opcode ba (invokedynamic requires --min-sdk-version >= 26) also other programs which compiled just fine with appcompat "earlier" refuse to compile now. Query: Is it possible to have a "known to work fine" androidx artifacts or their version (installed-components.txt) shared the same way SDK files in b4a installation process are ? What we are looking at basic appcompat and support files required by libraries like Drawer / Sliding panel / recycler / preferences. If anyone has a working set of working androidx, it would be nice if they can compress only the artifacts as defined in "installed-components.txt" (It would be a max of 30 ~ 50mb) Any other workaround/alternate solutions are welcome.

It does not specify which library (error msg shared above) I searched the b4x forums and found that similar error was caused by data transport libs which you resolved for someone else earlier by reverting to old version of same libs. I've done a fresh install. So I don't have logs now. However, it is a time consuming but reproduceable error. I can not use any project which require recycler or v4 support - it goes in the same loop as described in post 1 Upvote 0

Hey @Erel I have narrowed down the issue to Appcompat Library v4 My project uses drawer and is dependent on lib AppCompat and has the following line in code B4X: #Extends: android.support.v7.app.AppCompatActivity Please suggest a workaround which does not involve discarding appcompat features Upvote 0
