A while back I was dabbling with App-Inventor to get my hexy the hexapod working on my Nexus tablet. It was a fun project. Poor hexy is in pieces now, stripped for her servo’s. So.. for a variety of reasons, I sort of have an itch for looking at android programming again.
Doing a fair amount of googling, It looks like the thing to try is Android- Studio… Ok.
So I ran across setting up a android-studio on ubuntu via a PPA here:
http://www.webupd8.org/2014/05/install-android-studio-in-ubuntu-via-ppa.html?m=1
It took me a few minutes to figure out how to fire the darn thing up.
jonasthomas@JTLapTop:~$ /opt/android-studio/bin/studio.sh
So you think I be ready to fly….. nope.
JDK Required: ‘tools.jar’ seems to be not in Studio classpath.
Please ensure JAVA_HOME points to JDK rather than JRE.
Ok… So an interesting post on here
JDK = JRE + Development tools.
JRE = JVM + Libraries
JDK = {JVM + Libraries} + Development tools.
On the Tools.Jar I found a nice post here: http://stackoverflow.com/questions/17474963/android-studio-tools-jar-file-is-not-present-in-classpath
Hmm
jonasthomas@JTLapTop:~$ java -version

jonasthomas@JTLapTop:~$
Ok.. I have OpenJDK installed (Possibly when I installed Eclipse-Arduino) This seems to be working ok.. So I don’t want to hose that up.
Soo.. The previous post pointed me to here:http://arwankhoiruddin.blogspot.co.il/2014/01/android-studio-in-ubuntu-problem.html
jonasthomas@JTLapTop:~$ update-alternatives –config java
There are 3 choices for the alternative java (providing /usr/bin/java).Selection Path Priority Status
————————————————————
* 0 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 auto mode
1 /usr/bin/gij-4.8 1048 manual mode
2 /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java 1061 manual mode
3 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 manual modePress enter to keep the current choice[*], or type selection number:
Ok.. I think all I need to do is to a Path to studio.sh
Soo.. I added this to the top:
export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java
Well that didn’t work.
Some talked about just doing this.

sudo apt-get install openjdk-7-jdkOk… So that did it…
Its a bit strange that seems to have worked. I thought that I had the jdk already installed, but when I did the installed it didn’t give me a message back that it was installed already and libraries started loading up.. Go figure.
