Uninstalling selected parts of Android SDK on the command line

阅读更多关于 Uninstalling selected parts of Android SDK on the command line

问题 This is related to "Uninstall old Android SDK versions", except I'd want to do it on a headless Linux CI server (short on disk space). Does the android command line tool provide options for removing older parts of the SDK? With a quick look, the only things it can delete are AVDs. Did I overlook something? Alternatively, I guess I could just manually delete stuff from under SDK_HOME. But what things are safe to delete? Other candidates than these? I only need to support API level 14 and up,

Immutables-library generates the same immutable class twice

阅读更多关于 Immutables-library generates the same immutable class twice

When using the immutables.io annotation processor in a multi-module android app, the build fails, when a package-info.java file is used. I've managed to build a minimal test-project on GitHub to reproduce the issue: ImmutablesPackageInfoIssue The project consists of 2 modules: app: android application: @Value.Immutable is used in AndroidIm.java lib: java module: @Value.Immutable is used in JavaIm.java So basically, using immutables.io in both modules works fine. But when we add a package-info.java file (to the com.example package in the app module), the compilation fails with this error: com
