Android Studio error after ./studio.sh

Question

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\"

Answer 1

for openjdk: export JAVA_HOME=/usr/lib/jvm/default-java

but you would better use the oracle jre to run android studio

Answer 2

You must be sure that your jre and jdk works fine.

Run

$ sudo apt-get install default-jre

and then...

$ sudo apt-get install default-jdk

to make sure you have your javac path run

$ whereis javac

It should return something like this:

javac: /usr/bin/javac /usr/bin/X11/javac /usr/share/man/man1/javac.1.gz

If it does not work, you can try change the JAVA_HOME in /etc/enviroment file

Append JAVA_HOME="${/.../JVM_PATH}"

For example:

JAVA_HOME="/usr/lib/jvm/java-7-openjdk-amd64"

and then reload this file:

$ source /etc/environment

Answer 3

Although I have JDK installed and was pointing to it, i didn't have java-1.7.0-openjdk-devel installed (Fedora).

Answer 4

Here's how I solved the same problem in my system: Thanks for @user2533809

$sudo apt-get install openjdk-7-jdk
$ls /usr/lib/jvm/java-1.7.0-openjdk-i386
ASSEMBLY_EXCEPTION  bin  docs  include  jre  lib  man  THIRD_PARTY_README
$export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-i386
$./studio.sh 

Environment :

kesavan@kesavan-Ideapad-Z460:bin$ uname -a
Linux kesavan-Ideapad-Z460 3.2.0-59-generic-pae #0trisquel1 SMP Sat Feb 22 03:55:17 UTC 2014 i686 i686 i386 GNU/Linux

Answer 5

I solved this by installing the jdk. This sounds annoyingly simple but I missed it. I thought I Had installed the jdk, but I had actually installed the jre.

Wrong:

sudo apt-get install openjdk-7-jre

Right:

sudo apt-get install openjdk-7-jdk

As soon as I did that, it started up fine for me. The things we miss sometimes....

Answer 6

I solved the problem combining Jerome's and Jarod's answer:

1. Install JDK -- sudo apt-get install openjdk-7-jdk
2. Environment Variable -- sudo nano /etc/environment adding the following line:
3. JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-i386
4. Reboot, and Android Studio starts up. (I had added also a link to studio.sh to the main menu).

Also I just found https://stackoverflow.com/a/17827697/2533809 which seems to have a nice write-up, pretty much the same answer.
