With my old projects it works fine. With new created by A.S "make project" it looks ok, but when I launch it at emulator it starts but I have over 100 console errors.

Could you tell me what's a problem here, or I have to reinstall it?

Change the JDK location to new version (i.e >1.6). You change it on Studio going **File > Project Structure > SDK Location** make like _C:\Program Files\Java\jdk1.7.0_60_ have a look this post [unsupportedclasserror](http://stackoverflow.com/a/2906852/5955593) — Kathi, Mar 23 '16 at 15:33
Included the console errors in the post as a code snippet for later reference when the txt URL gives a 404. — Frank van Wijk, Mar 23 '16 at 15:42

on your gradle are you working with buildToolsVersion 24 RC1 ? if yes change it to '23.0.2' and compile with jdk 1.7
