Hi, I deleted the "android" and "java" directories, downloaded the version from
https://www.b4x.com/b4a.html and installed them again.
Now I have installed openjdk instead of the previous java 8 oracle.
The problem persists in the same way.
If I compile from the command line, it works fine.
I have to copy the "apk" by ftp from the b4a bridge.
Apparently the adb.exe is damaged. But I downloaded it again, as I counted before, and it still has the same problem.
Thank you.
