Hi,
I decided to write this as a reference to help install and setup the proper JDK for building Android. NOTE --- this can also be found here: [GUIDE] Setup Android Development Environment on Ubuntu 14.04 Trusty Tahr. I know this works for Ubuntu 12.04 (Precise) up to 14.04 (Trusty Tahr). I will also show a variation which is (in my opinion) easier to get the JDK. One more thing to note, there are couple of things I will point out that are needed to resolve build issues with Kit Kat 4.4. On with the guide.
Installing Sun JDK 6
Add PPA to system
$ sudo add-apt-repository ppa:webupd8team/java
Download & install java
$ sudo apt-get update && sudo apt-get install oracle-java6-installer
CHECK
$ java -version
You should see something like:
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)
If not (I have had trouble with this i the past), do to this variation:
http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase6-41940...
(in your browser and manually download)
You will have to login or setup an account with Oracle if you do not have one.
Put the "jdk-6u45-linux-x64.bin" in the home directory.
We need to run the binary and move it to a shared location by opening a terminal and typing:
$ chmod +x jdk-6u45-linux-x64.bin
$ sudo ./jdk-6u45-linux-x64.bin
$ sudo mv jdk1.6.0_45 /usr/lib/jvm/
Now you have to install all binaries and give them highest priority, This will also overwrite the previous version of Java Binaries in your computer:
$ sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.6.0_45/bin/java 1
$ sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.6.0_45/bin/javac 1
$ sudo update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.6.0_45/bin/javaws 1
$ sudo update-alternatives --install /usr/bin/jar jar /usr/lib/jvm/jdk1.6.0_45/bin/jar 1
$ sudo update-alternatives --install /usr/bin/javadoc javadoc /usr/lib/jvm/jdk1.6.0_45/bin/javadoc 1
$ sudo update-alternatives --install /usr/bin/javap javap /usr/lib/jvm/jdk1.6.0_45/bin/javap 1 (NOTE - This is needed to compile Kit Kat 4.4)
(Most of the time after these commands, I basically get that the jdk is not there. Just run the binary and move it to a shared location using the three commands above again,install, and give them the highest priority again...its a pain, I know)
Now check if JDK 1.6 is selected on this:
$ sudo update-alternatives --config java
$ sudo update-alternatives --config javac
$ sudo update-alternatives --config javaws
$ sudo update-alternatives --config jar
$ sudo update-alternatives --config javadoc
$ sudo update-alternatives --config javap (NOTE - This is needed to compile Kit Kat 4.4)
These six alternatives should all be selected.
Now the JDK is configured! To check if it is done
Execute this is Terminal:
$ java -version
Output will be similar to this:
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)
IF NOT, YOU MAY NEED TO RUN AGAIN
The JDK is now configured. You can now delete or save somewhere else "jdk-6u45-linux-x64.bin" that is in the home directory.
