My Android app—written in a mix of Java and Kotlin—is feature-complete, but it refuses to compile. As soon as I hit “Sync with Gradle,” eleven errors pop up, all pointing to missing or unrecognised XML layout files. Moments earlier those same layouts open and preview just fine, so something in the sync process is causing them to disappear from the build. I need someone who can jump into the project, trace the root cause inside the XML resources, and leave me with a project that builds cleanly in Android Studio (Electric Eel). A concise summary of what was wrong and how you fixed it will help me avoid the issue next time. If you have a solid track record debugging resource-related build failures and Gradle quirks, this should be a quick win for both of us.
