After ./studio.sh
in a terminal I get this error \"tools.jar is not in android studio classpath Please ensure JAVA_HOME
points to JDK rather than JRE\"
I have figured it out. You need to install openjdk-jdk. Opensjdk-jre is not enough. So in terminal all you need to do is write sudo apt-get install openjdk-7-jdk
then press yes. Open the android studio bin folder, double click on studio.sh, open in terminal, press enter, and then android studio should work.
