Hi, I tried to import support/ui in AS but got ‘Basedir support/ui/annotation does not exist’ error. I followed the steps in README.md in the same folder. AS version is 4.1 Canary 10.

run ./gradlew studio and it will give you a correctly configured android studio installation of the expected version

[Adam Powell]

(from the ui/ subdirectory)

[Adam Powell]

you should not need to import the project explicitly

[Hanzhen]

I tried this as well, but had error: ‘Android Studio*.app not found’. After copied studio folder from ‘support’, I can open AS from the command. But still had the same error.

Seems includeProject in settings.gradle can not set projectDir correctly.

[Hanzhen]

My gradle version is 6.5

[Adam Powell]

what OS and version are you running on your development machine?

[Hanzhen]

macOS Mojave 10.14.6

I figure out what was going on. I exited ./gradlew studio before it was finished, so studio task thought AS was updated but in fact it didn’t. I reported the issue and pushed a fix: https://android-review.googlesource.com/c/platform/frameworks/support/+/1333982

Yet I still couldn’t start the studio:

I update AS to 4.1.0.10, now it can be started.

[Hanzhen]

Do you have the same issue? Should I report it?

[Hanzhen]

But project can not sync because of this error: Basedir /*/androidx-master-dev/frameworks/support/ui/annotation does not exist .

[Hanzhen]

I think it’s because how we include the project, for instance: includeProject(":annotation:annotation-sampled", "../annotation/annotation-sampled") , it will not only include ``annotationannotation-sampled``, but also parent project ``:annotation``, and for the parent project, it will try to search dir ui/annotation which is rootProjectDir/projectPath . In this case, apparently we don’t have support/ui/annotation but support/annotation .

[Hanzhen]

Solution would be include parent project manually in settings.gradle .

[Hanzhen]

After fixed above issues, AS asked me to upgrade Android Gradle Plugin to 4.1.0-alpha10 .

[Hanzhen]

@Adam Powell I still can not make it.

[Adam Powell]

there is often a warning in the project about the duplicate project roots but I've never seen it refuse to proceed from there. Is that warning masking another error somewhere?

[Hanzhen]

@Adam Powell I deleted caches of Android Studio, everything is fine now.
