I can't test it, but looks fine to me 👍

After my corrections (in local clone) I checked and it is working, I see log files are created.

Amazing, thanks @AlexShafir. And you set the path or used the Android default?

[AlexShafir]

I had to set path, on my phone default path crashed:
terminating due to uncaught exception of type std::__ndk1::__fs::filesystem::filesystem_error: filesystem error: in create_directory: Permission denied ["/data/local/tmp/mavsdk-component-metadata-857cfc8c"]

I used this path to set:

val folder = File(context.filesDir, "logs")
if(!folder.exists()) folder.mkdir()
mMavsdkServer.setTempDirectory(folder.absolutePath)
