Description
Lets Android Studio work with an SDK directory that would otherwise be read-only by placing a writable UnionFS layer over it. This helps when the IDE expects to update SDK files but the packaged SDK is protected by the system package manager.
Developers use it as a compatibility helper for Android Studio setups, not as a general Android SDK replacement. Because it changes how SDK files appear to the IDE, keep backups or know where the real SDK data is stored before troubleshooting build problems.
