i'm a newbie on linux, android and QA at the same time.

following this tutorial:
http://developer.android.com/tools/testing/testing_ui.html#sample
I came across to this situation: 

filip@TowardMac:~/workspace_adt/TestSample$ ant build
Unable to locate tools.jar. Expected to find it in /usr/lib/jvm/java-7-openjdk-amd64/lib/tools.jar

Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "/usr/lib/jvm/java-7-openjdk-amd64/jre"

    Did you look at the error? Is your JAVA environment configured properly? – Phil Kirkham Nov 19 '13 at 20:15
  • @peter: I didn't know that at the time. As I've said I was beginner at all posible fields. Thank you for your time. – MiniBug Mar 25 '14 at 8:54

It looks like you did not define Java. Please add JAVA_HOME to .bashrc

  • That seems to be the problem. Although, I add JAVA_HOME to '/etc/profile'. Which approach to the problem is better in your opinion? Thank you for your time. – MiniBug Mar 25 '14 at 8:58
  • What kind of shell do you use? Each shell has configuration file. Add JAVA_HOME to .bashrc if you use bash for your user and to .zsh, for example, if you use zsh. I prefer to add JAVA_HOME to .bashrc configuration file. But your decision is not bad too :) – amazpyel Mar 25 '14 at 9:56
  • I use bash. Can you tell me your point of view - why do you prefer it? I love my solution only coz it's working :-) – MiniBug Apr 4 '14 at 18:18
  • I use bash too but I have several workstation (home, office, etc.). So I can just put same .bashrc on each workstation. – amazpyel Apr 4 '14 at 19:12
