Android Question [SOLVED] Problems with B4A

[hatzisn]

Today out of the blue I started having problems compiling with B4A.

Firstly it asked me to install androidx.work:work-runtime.
I did install it from SDK manager and now it asks me to install the com.google.guava:listenablefeature which is not apparent in the SDK Manager list even with search.
What am I supposed to do? Did I missed something?

Maven artifact not found: com.google.guava/listenablefuture (SOLVED)

Just updated the SDK through the B4A SDK Manger and now I get the "Maven artifact not found: com.google.guava/listenablefuture". I tried searching for it, and this is closest one installed: I see that others had this issue in the past - seems that updates to the SDK Manager to 3.6 fixed it...

maybe this help:

The error seems to occur only in Debug Mode. Perfect. I cannot work.

It is as if I have the curse of the American Indian: Where ever you go may there be a cloud above you and rain.

It gets better and better. Having set MaxRamForDex=4096 I get the following error.

It seems to have been solved with:

1) Complete uninstall of B4A
2) Deletion of Java jdk folder
3) Deletion of Android folder
4) Downloading again the Java JDK from B4A's page
5) Downloading from Google the latest tools (you can see it after clicking on the link "SDK license" in B4A page).
6) Renaming the folder cmdln-tools to tools
7) Downloading the required resources from B4A's page
8) Reinstalling B4A

I have not tried to use the SDK manager to update and I am afraid to do so. But I will do it when I will have finished my job.
