Android Studio and android.support.v4.app.Fragment: cannot resolve symbol

I am tryng out Android Studio instead of Eclipse. I install it and then start a completely new project and follow the wizard. I add no code of my own.

Then, I right-click to create a new component, a new Fragment:

and choose a new fragment:

and as soon as I do, I see compile errors:

... so I start googling and find out that I need to install and reference support library 4, and that I do. When I check the build.gradle (whatver that is, new to me coming from Eclipse), I see:

but I change that to

because they said so here. After recompiling and all that, the error is still there. I then reference the .jar-file directly, like this:

and again do recompile yada yada, but that doesnt help either.

This behaviour seems very strange to me. What am I missing here? This is the SDK Manager view:

So, what am I missing? Thanks =)

Answer

The symptom of this problem is usually that the build works fine from the command line (which means your build.gradle file is set up right) but you get syntax highlighting errors in the IDE. The solution is to click the Sync Project with Gradle Files button in the toolbar. We realize it's less than ideal that the IDE can't just take care of itself instead of forcing you to manually sync at the right time; we're tracking progress on this in https://code.google.com/p/android/issues/detail?id=63151
