I know it has been asked several times, but I tried every suggested solution and the problem still persists. In code files, I can go to declaration of variables by pressing + as usual, it even jumps to xml files. But in XML layout files, I have no intellisense autocompletion, nor can I jump to declaration to other resources.
I tried cleaning and rebuilding the project, deleting .idea and build directories, deleting recursively all .iml files, the "Invalidate Caches and Restart" options in the File menu, creating a new project from scratch (it has just the same problem),...
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/app_name"
/>
It even says "Unknown attribute android:text"
