Android Studio cannot import project: java.util.ArrayList cannot be cast to java.util.Map

Question

When I'm trying to import my project through Android Studio I get this error.

I have used gmaps in the project. How do I resolve this error?

I've already re-installed Java and reset JAVA_HOME. I've also made sure Gradle is set up properly.

I'm using Studio 0.3.2 and Gradle 1.9 on a Windows 7 - 64 bit PC.

Answer 1

You can use android studio 0.4.0. Gradle version 1.9 isn't compatible with Studio 0.3.2.
