on new project start, android studio cannot resolve symbol R, after rebuild/clean shows 2 errors

Question

I'm using Ubuntu 14.04 32-bit.

When I installed android studio, on the first start, there was an error about java jdk path. When I changed the path to the right folder and gradle runs automaticlly, it doesnt finish, but outputs 2 errors. When I run the app or anything else that runs the gradle, the gradle then runs forever.

Also, in main_activity.java the R is red and popus says that they cannot resolve symbol.

Anybody knows what might be the problem? Thank you in advance

Here is the log
