Unable to resolve imports from Android Support Repository

I used the Android SDK Manager to install the Android Support Repository. When I now try to import something from there (e.g. android.support.v4.content.LocalBroadcastManager) into the Android app of my Flutter app, IntelliJ is unable to resolve it:

Cannot resolve Symbol 'LocalBroadcastManager'

The app compiles just fine with that import though. I played around a little with the “Project Structure…” settings, but without much success. It seems like there is no jar for the Android Support Repository on disk that I can include.

Would be nice to document how you can add and use stuff from the Android SDK with the new “Editing Android code in IntelliJ IDEA” support in IntelliJ with Flutter.

I tried to reproduce this, and I think the issue is with how we set up the projects, as well as a little hiccup with Android dependencies.

Here’s what I did:

• flutter create foo
• Open foo/android in IDEA. Let it import the project from Gradle.
• Added compile 'com.android.support:support-v4:25.3.1' dependency in android/app/build.gradle`.

At this point, I would normally expect a Gradle sync in IDEA to pick up the added dependency and just work, but it didn’t. I actually had to

• Build -> Build Project

After that, LocalBroadcastManager (and whatever else I wanted from support) was available in IDEA.

So, looks like the Android dependencies are fetched from the android/build directory, since LocalBroadcastManager stopped working in the IDE when I removed that directory.

I don’t think we should try to work around this, and if we do, it should only be temporary until this issue is fixed upstream.

Also note that I didn’t open foo/ in IDEA. That project doesn’t look like it’s set up correctly for native Android development. In particular, it doesn’t look like it uses Gradle, and it didn’t pick up the new dependency even after I’d built the project.
