On the other hand, when run a Espresso test any error doesn't occurs

Environment:

Gradle 1.10

JDK 8

Last update of Android SDK

Thanks!

Answer 1

I also ran into this issue, I'll leave an answer here in case it helps anyone else that runs across this post when searching for this error. For me, it was that the version of Robolectric (or more specifically, the version of ASM it relies on) didn't work with Java 8. Upgrading from Robolectric 2.2 to 2.3 fixed this for me.

Answer 2

Solved. The error was caused by a version conflict in the .gradle folder (gradle-1.10 vs gradle 1.11). Deleting the .gradle folder and regenerating gradle fixes the problem.
