How to use the extension with an Android project?

[marmistrz]

I have a simple Android project. I opened it in VS Code after installing the extension, but the Android-specific imports or the R.* paths are not found by the extension.

KLS seems to have some support for Android projects: https://github.com/fwcd/kotlin-language-server/commit/97b0282e69145788a8099bad3ed6b333c3958e3e

[fwcd]

Which build tool do you use? The Android support provided by KLS currently only supports Gradle (as implemented here).

[marmistrz]

I'm using gradle, I opened this project: https://github.com/marmistrz/OpenMeteo

I'll paste a log in a while

[marmistrz]

It appears that after restarting VS Code the Android project is correctly opened, all the Android specifics are recognized. Maybe the extension needs an editor restart to work properly?

[fwcd]

That's interesting, usually it shouldn't. But if it works for you now, that's great.

Feel free to reopen if this issue occurs again.

It looks like something tenaciously recreates the gradle wrapper which I don't want to use - I have my distribution for that.

[fwcd]

The language server does not create a wrapper, it just continues to search the PATH for a Gradle executable if no wrapper is present (see here). In this specific case, the LS apparently finds a gradlew in the OpenMeteo repo folder that does not have executable permissions and throws an exception in an attempt to read it.

[RealYukiSan]

I have add the gradlew to the PATH variable and also export ANDROID_SDK variable, but the extension cannot resolve the androidx package (UNRESOLVED_REFERENCE) even though the gradlew successfuly build and generate apk.

any guide how to fix this?
