I have a problem trying to install android Studio on Ubuntu 14.04. I get the following error:
ERROR: Cannont start Android Studio
No JDK found. Please validate either STUDIO_JDK, JDK_HOME or JAVA_HOME environment variable points to valid JDK installation.
I was already investigating and I only found a solution in Windows in which environment variables have to be created, but in ubuntu I can not find anything, and it is assumed that I already have the JDK installed.
You can set your variable JAVA_HOME in /etc/profile but preferably save JAVA_HOME or any system variable in /etc/environment .
Open /etc/environment in nano or gedit and add the following:
JAVA_HOME="/usr/lib/jvm/jdk" (The route may be different depending on your machine)
Now run the following command to load the variables:
source /etc/environment
Then check the contents of your variable with the following command:
echo $JAVA_HOME
If the route is printed on the screen, you have done it correctly and the same applies to the other variables.
