I install the studio, but when I run it, an error occurs:
'tools.jar' seems to be in Android Studio classpath.
Please ensure JAVA_HOME points to JDK rather than JRE.
In the JAVA_HOME variable, I entered the path C: \ Program Files \ Java \ jre7
I understand that Android requires the installation of the JDK, but where to get it, at the office. the site he gives install only JRE.
