I have installed Android Studio and I followed all steps described here
But when I start studio.sh I got an error with this message:
studio.sh
The error is self explanatory, you need to set your environment variable to JDK path instead of JRE here is it
JDK_HOME: C:\Program Files\Java\jdk1.7.0_07
check the path for linux
and here is possible duplicate Android Studio not working
