When I type ctrl-q in Android Studio, the documentation opens, works fine. But if I have API calls from the support library (like ContextCompat.getExternalFilesDirs), I see a more or less empty window.
But it workes some updates ago?! IIRC?!
The code compiles and works, I did not change anything but installing Android and Studio updates... Now it's Android Studio 0.9.2, Support Libraray 21.0.1
In build.gradle I have com.android.support:support-v4:21.0.+, and "0.1" not working, only "0.0" or "0.+". Kind of library version mismatch?
