Android Question sdkmanager help needed.

[Johan Schoeman]

I was trying to revive an old B4A project using B4A V13.0
While compiling the B4A project it called for:

androidx.resourceinspection:resourceinspection-annotation
androidx.transition:transition-ktx

So, started SDKManager from within the B4A project, searched for the dependencies, and installed them.

But it does not install them in the correct folder. It installed it in folder.....

C:\Android\commandlinetools-win-9123335_latest\extras\b4a_remote\androidx

...while it should have been installed in folder....

C:\Android\extras\b4a_remote\androidx

I copied the installation folders (installed via SDKManager) from the "wrong" folder to the "correct" folder, then manually updated....

installed-components.txt

...and the project then compiled successfully.

This is the B4A code after I copied the dependencies to the correct folder and updated the txt file :

Question why are the dependencies installed to the incorrect folder? Does it have something to do with my configuration paths? The config paths seem to be correct as all other project are working.

 

[drgottjr]

there was a similar case recently. i'm pretty sure erel said to copy the jar to your add'l libraries folder after you find in the sdk's extras.

No need to copy any jar.

Maybe the path to sdkmanager.bat in the sdk manager is wrong. Compare it to the path to android.jar under Tools - Configure Paths.
