Android Source code build error - android

I am trying to build android source code in my Linux machine(Ubuntu 12.04 64bit). when I am start building it...i am getting error as follows
============================================
Checking build tools versions...
************************************************************
You are attempting to build with the incorrect version of java.
Your version is: java version "1.6.0_24". The correct version is: Java SE 1.6.
Please follow the machine setup instructions at
https://source.android.com/source/download.html
************************************************************
build/core/main.mk:141: *** stop. Stop.
I am able to understand the problem but I don't know how to change my java version because while installing jdk from terminal i am getting "1.6.0_24" version by default.
Please do needful.
Thanks In advance.

Install Java SE 1.6 and use sudo update-alternatives --config java to set to that java version.
You can download Java from here http://www.oracle.com/technetwork/java/javase/downloads/index.html

1.) If you’ve already installed OpenJDK (Or in ubantu generally it is already installed). Remove it by running this command:
sudo apt-get purge openjdk*
2.) Then:
sudo add-apt-repository ppa:webupd8team/java
Then update:
sudo apt-get update
3.) Select which version you want
To install Oracle Java 8:
sudo apt-get install oracle-java8-installer
To install Oracle Java 7:
sudo apt-get install oracle-java7-installer
To install the Java 6:
sudo apt-get install oracle-java6-installer

installing android studio on ubuntu

everybody, I am the android developer, I am using ubuntu 14.04 LTS.
Because of some hardware problem, I have to format my PC. before that android studio , SDK and Java were working perfectly.
After formatting my PC. I installed jdk1.8.0_71. after i extract android studio deb file with command sudo dpkg -i android-studio_4.13.0-ubuntu0_all.deb
and 'android-studio' folder extracted at /opt directory.
after that, i try to run /opt/android-studio/bin/studio.sh with command.
sh ./studio.sh and it gives me error like this
I have also tried by ./studio.sh to execute but same error. please help to solve.
To install Oracle Java on Ubuntu, do this:
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
I do this every time I install an Android Studio and it works flawlessly. And your Java 8 will be kept up to date, too. The environment variables are automatically properly set by that procedure.
its all about ELF execution (when you get bushes in output)
when your 64 bit os tries to start the Android SDK which in turns tries to run some 32 bit binaries and thus is the issue of compatibility.
check you have proper libs installed for studio
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6
64-bit architecture your you need
sudo apt-get install libncurses5:amd64 libstdc++6:amd64 zlib1g:amd64
and 32 bit:
sudo apt-get install libncurses5:i386 libstdc++6:i386 zlib1g:i386
for details see:
https://developer.android.com/studio/install.html
ps if apt could not find such libs try to search for similar - the name can vary for different distro
also use proper java hotspot (jdk) 32/64bit for your system
Setting up Android Studio takes just a few clicks.
While the Android Studio download completes, verify which version of the JDK you have: open a command line and type javac -version. If the JDK is not available or the version is lower than 1.8, download the Java SE Development Kit 8.
To install Android Studio on Linux, proceed as follows:
Unpack the .zip file you downloaded to an appropriate location for your applications, such as within /usr/local/ for your user profile, or /opt/ for shared users.
To launch Android Studio, open a terminal, navigate to the android-studio/bin/ directory, and execute studio.sh.
Tip: Add android-studio/bin/ to your PATH environment variable so you can start Android Studio from any directory.
Select whether you want to import previous Android Studio settings or not, then click OK.
The Android Studio Setup Wizard guides you though the rest of the setup, which includes downloading Android SDK components that are required for development.
Note: If you are running a 64-bit version of Ubuntu, you need to install some 32-bit libraries with the following command:
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6
If you are running 64-bit Fedora, the command is:
sudo yum install zlib.i686 ncurses-libs.i686 bzip2-libs.i686

I had similar problems with finding java by starting android-studio on ubuntu.
I solved the problems by editing the studio.sh file.
In the file the JAVA_HOME variable should be set, but it wasn't.
So I set the JAVA_HOME variable in the script manually and I could start android-studio.
Finally i solved my problem bu reinstalling java properly. i thought i installed wrong java/jdk. now Android Studio,Java is working.
I found this link useful to install java step by step. Link to install java step by step
Install Android Studio in ubuntu :
At first install JDK
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
sudo apt-get install oracle-java8-set-default
Download the android studio from here
https://developer.android.com/studio
Unzip android studio tar file using :
sudo unzip android-studio-ide-141.2178183-linux.zip -d /opt
or Simply unzip the download file using Archive Manager
Goto to android-studio/bin folder and open terminal or in terminal type
/opt/android-studio/bin
Then type :
./studio.sh
Android studio lunch your computer.
It takes about 30 min to one hour to finish gradle.
There recommend some updates and you should provide those updates.
For installing app using your phone, open developer mode. If you cannot see developer options go to about phone and tap build version 8 times.
In developer options turn on usb debugging.
Connect the phone into the computer using a USB cable.
Give a commands : sudo apt install adb
On the phone there is a dialog for debugging permission. Provide the permission.
Then install the app.
For saw the program in desktop goto tools->Create Desktop Entry-> Ok
Please, try to install java 7 or openjdk. It must solve problem.

I am unable to install Android Studio on Linux mint 17.1

I have tried for a lot times, but failed.
The Problem Details: I used these commands
sudo apt-add-repository ppa:paolorotolo/android-studio
sudo apt-get update
sudo apt-get install android-studio
When i command the first line into the terminal it didn't notice me to getting any error. But after commanding the second line it got error..
There is the screenshot of that Error ...
The official distribution of Android Studio can be downloaded here. You're trying to use an unofficial repository maintained by someone from the community; there is absolutely no guarantee that it's going to work. Please consider downloading the official distribution instead.
So, first you want to make sure your Java is properly installed. You can do this manually or with a PPA.
Manual Method:
Get rid of the Open JDK that may be installed:
sudo apt-get update && apt-get remove openjdk*
Download Oracle JDK from here. You are looking for a linux version
with tar.gz extension. Also choose the right version from 32-bit
(x86) and 64bit (x64) one.
sudo mkdir -p /opt/java
Move the unzipped download to where it will live (I put the version
number in this example):
sudo mv jdk1.8.0_91 /opt/java
Make this JDK your system's default:
sudo update-alternatives --install "/usr/bin/java" "java" "/opt/java/jdk1.8.0_91/bin/java" 1
sudo update-alternatives --set java /opt/java/jdk1.8.0_91/bin/java
Finally, test your Java version:
java -version
PPA Method:
Get rid of the Open JDK that may be installed:
sudo apt-get update && apt-get remove openjdk*
ADD PPA
sudo add-apt-repository ppa:webupd8team/java
UPDATE
sudo apt-get update
INSTALL
sudo apt-get install oracle-java8-installer
Now Install Android Studio - either manually or via PPA:
Manual Method:
Download android studio:
Get it from http://developer.android.com/sdk/installing/studio.html#download then untar it under /opt/android-studio (recommended).
Launch it!
run ./studio.sh in the /opt/android-studio/bin directory. This will launch the setup and download all the SDKs and other necessary files on your first run, and this is what you will do to launch in the future. Just make a shortcut :)
PPA Method:
ADD PPA
sudo add-apt-repository ppa:paolorotolo/android-studio
UPDATE
sudo apt-get update
INSTALL
sudo apt-get install android-studio
NOTE: This PPA is maintained by Google, not just "someone from the community"

How to install Android Studio on Ubuntu?

I have to install Android Studio on Ubuntu and I have used this link to download Android Studio.
Is there any easy way to install Studio on Ubuntu?
Below are the steps to install Android Studio in Ubuntu system:
1. Install JDK 6 or later
First, install Oracle JDK 8 (although you could also choose OpenJDK but it has some UI/performance issues) using WebUpd8 PPA.
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
sudo apt-get install oracle-java8-set-default
To make sure, it’s installed successfully, open a terminal and type (you should get the version number of the jdk you’ve installed e.g javac 1.8.0_11)
javac -version
2. Download and install Android Studio
Download the Android Studio package for Linux and extract it somewhere (e.g home directory).
Then type :
cd android-studio/bin
./studio.sh
3. Install SDK Platforms
You need to install some SDK before you jump into building android apps. Click on Configure -> SDK Manager to open Android SDK Manager. Select the latest API (to test against target build, e.g API 19 (Android 4.4.2)) and some packages in Extras (Android Support Library and Android Support Repository). Then install the selected packages.
Download the Linux SDK from the Android website.
Copy the folder to whereever you want to extract the contents.
Open a terminal there, and then run:
sudo apt-get install unzip
sudo tar xvzf android-studio-ide-135.1641136-linux.zip
cd android-studio-ide-135.1641136-linux
./studio.sh
JDK 1.7 is required for Studio 1.0 onwards:
Download the ubuntu zip from the d.android.com and repeat the steps from above
Download the jdk 1.7 by executing the following commands in terminal as mentioned webupd8:
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
Open Android Studio and install the SDK tools.
Caveats:
If your system has a 32 bit processor, use Platform Tools r23.0.1.
Refer to this bug for details.
Note: If you are running a 64-bit version of Ubuntu, you need to install some 32-bit libraries with the following command:
$ sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1
Source: - linux-32-bit-libraries
Run the following command on terminal.
sudo apt-add-repository ppa:paolorotolo/android-studio
sudo apt-get update
sudo apt-get install android-studio
Don't forget to run:
/opt/android-studio/bin/studio.sh
when you are done installing.
The easiest method to install Android Studio (or any other developer tool) on Ubuntu is to use the snap package from Ubuntu Software store. No need to download Android Studio as zip, try to manually install it, add PPAs or fiddle with Java installation. The snap package bundles the latest Android Studio along with OpenJDK and all the necessary dependencies.
Step 1: Install Android Studio
Search "android studio" in Ubuntu Software, select the first entry that shows up and install it:
Or if you prefer the command line way, run this in Terminal:
sudo snap install --classic android-studio
Step 2: Install Android SDK
Open the newly installed Android Studio from dashboard:
Don't need to import anything if this is the first time you're installing it:
The Setup Wizard'll guide you through installation:
Select Standard install to get the latest SDK and Custom in-case you wanna change the SDK version or its install location. From here on, it's pretty straightforward, just click next-next and you'll have the SDK downloaded and installed.
Step 3: Setting PATHs (Optional)
This step might be useful if you want Android SDK's developer tool commands like adb, fastboot, aapt, etc available in Terminal. Might be needed by 3rd party dev platforms like React Native, Ionic, Cordova, etc and other tools too. For setting PATHs, edit your ~/.profile file:
gedit ~/.profile
and then add the following lines to it:
# Android SDK Tools PATH
export ANDROID_HOME=${HOME}/Android/Sdk
export PATH="${ANDROID_HOME}/tools:${PATH}"
export PATH="${ANDROID_HOME}/emulator:${PATH}"
export PATH="${ANDROID_HOME}/platform-tools:${PATH}"
If you changed SDK location at the end of Step 2, don't forget to change the line export ANDROID_HOME=${HOME}/Android/Sdk accordingly. Do a restart (or just logout and then log back in) for the PATHs to take effect.
Tested on Ubuntu 16.04LTS and above. Would work on 14.04LTS too if you install support for snap packages first.
Note: This question is similar to the AskUbuntu question "How to install Android Studio on Ubuntu?" and my answer equally applies. I'm reproducing my answer here to ensure a full complete answer exists rather than just a link.
Here's how I installed android studio on xubuntu.
1. Install JDK:
Go through following commands to install jdk
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
sudo apt-get install oracle-java7-set-default
If you want to install other version of jdk than replace your version number with 7 in last two commands.
2. Download the latest android studio from official site:
https://developer.android.com/studio/index.html
It is better to use latest version of android studio because I tried to install version 1.5.1 and it was not working. Then I installed version 2.1.1 and it run perfectly.
Extract downloaded android studio file in whichever folder you want.
Now go to extracted android studio-->bin directory and open terminal here. Now run following:
./studio.sh
And that's it. If you are facing any problem than comment below.
You can also Install using a PPA
link
In order to install Android Studio on Ubuntu Studio 14.04 and derivatives, do the following:
Step 1: Open a terminal using the Dash or pressing Ctrl + Alt + T keys.
Step 2: If you have not, add that repository with the following command:
sudo add-apt-repository ppa:paolorotolo/android-studio
Step 3: Update the APT with the command:
sudo apt-get update
Step 4: Now install the program with the command:
sudo apt-get install android-studio
Step 5: Once installed, run the program by typing in Dash:
studio
you can install android studio by following steps in the terminal :
sudo apt update
sudo apt install openjdk-8-jre
sudo add-apt-repository ppa:maarten-fonville/android-studio
sudo apt update
sudo apt install android-studio
make sure you have no error in installation.
Android Studio PPA is maintained by Paolo Rotolo. We just need to add PPA to our system and install it using the following commands:
$ sudo add-apt-repository ppa:paolorotolo/android-studio
$ sudo apt-get update
$ sudo apt-get install android-studio
For more, see allubuntu.com
To install android studio on ubuntu here is the simplest way possible:
First of all, you have to install Ubuntu Make before installing Android Studio. Type following commands in the same order one by one on terminal:
1) sudo add-apt-repository ppa:ubuntu-desktop/ubuntu-make
2) sudo apt-get update
3) sudo apt-get install ubuntu-make
Now since you are done with Ubuntu make, use below command to install Android Studio:
4) umake android
While installation it will give you a couple of option which you can handle. So, Installation is done. You can open it and run an App of your choice. Isn’t it very easy? Let me know if you go through any problem, I can help.

Android Studio is now integrated in JetBrains Toolbox:
This free tool allows to easily install all JetBrains products, and Android Studio as well. Upgrade is automatic.
On Ubuntu, this tools requires FUSE (Filesystem in Userspace)
Hi If you want to install android studio on ubuntu you shoudl first have Java JDk on ubuntu.
Installing Java SDK
First you have to install Oracle on Java 7 (JDK and JRE)
Download Java SDK 32 or 64 bit depending upon your version.
java sdk on ubuntu
Then extract the file in the /tmp folder.Al dialogue box will pop up, click on replace all.An error will also pop out click close.
Go to tmp folder,a new folder name jdk and version must be created.right click on the folder and then click on rename and copy the name of the folder.

I was just investigating this issue now, you should use Ubuntu Make
Which "is a command line tool which allows you to download the latest version of popular developer tools on your installation"
You could always follow the official guide on how to install Android Studio on Linux. There's even a video you can watch!
https://developer.android.com/studio/install.html
Remember to select Linux in the drop-down box.
To summarise the steps: download Android Studio and extract it and execute studio.sh to run it. If you're running 64-bit Ubuntu, you will need to run:
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6
Follow the steps via terminal:
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
after then:
sudo apt-get install oracle-java8-set-default
then;
Download Android Studio from "https://developer.android.com/studio/index.html", use All Android Studio Packages.
Unzip the file.
At last type via terminal :
cd android-studio
cd bin
./studio.sh
Then follow the commands and you're ready to go.

Error to run Android Studio

I have installed Android Studio and I followed all steps described here
But when I start studio.sh I got an error with this message:
'tools.jar' is not in Android Studio classpath. Please ensure JAVA_HOME points to JDK rather than JRE
Can anyone here help me with this?
Check if your Java JDK is installed correctly
dpkg --list | grep -i jdk
If not, install JDK
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update && sudo apt-get install oracle-java8-installer
After the installation you have to enable the jdk
update-alternatives --display java
Check if Ubuntu uses Java JDK 8
java -version
If all went right the answer should be something like this:
java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)
Check what compiler is used
javac -version
It should show something like this
javac 1.8.0_91
Finally, add JAVA_HOME to the environment variable
Edit /etc/environment and add JAVA_HOME=/usr/lib/jvm/java-8-oracle to the end of the file
sudo nano /etc/environment
Append to the end of the file
JAVA_HOME=/usr/lib/jvm/java-8-oracle
You will then have to reboot, you can do this from the terminal with:
sudo reboot
In case you want to remove the JDK
sudo apt-get remove oracle-java8-installer
sudo apt-get install default-jdk
That's all in ubuntu 11
This is caused by having JAVA JRE installed as opposed to JAVA JDK.
The solution is simple:
sudo apt-get install openjdk-7-jdk
http://www.maxmakedesign.co.uk/development/2013/android-studio-tools-jar-classpath/
The error is self explanatory, you need to set your environment variable to JDK path instead of JRE here is it
JDK_HOME: C:\Program Files\Java\jdk1.7.0_07
check the path for linux
and here is possible duplicate Android Studio not working
Widows 7 64 bit.
JAVA_HOME point to my JRE (NOT JDK) directory
Coping of tools.jar from JDK\lib directory to ANDROIDSTUDIO\lib directory solve the problem
in OpenSuSE 13.1 and some 13.2 versions you also need to:
install java-1_7_0-openjdk-devel package
change the JAVA_HOME path when starting the studio:
For x86:
JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0/ sh studio.sh
For x64:
JAVA_HOME=/usr/lib64/jvm/java-1.7.0-openjdk-1.7.0/ sh studio.sh
I had the same problem on a new installed Linux Mint 16. To fix this you just need to type command
sudo apt-get install openjdk-7-jdk
And that's it. You even do not need to add repositiries or creating JAVA_HOME in your environment.
On ubuntu I have tried all the methods that are described here but none worked.
What I did in the end was to:
download JDK from oracle, extract the archive
edit android-studio/bin/studio.sh and add at the top
export JAVA_HOME=/path/to/jdk
save the file and cd android-studio/bin and launch Android Studio: ./studio.sh
For me, running Fedora 22 with Gnome 16.2, this solution helped me.
In short, you should install the java-1.8.0-openjdk-devel, the development files of the JDK.
Open the Terminal and search for the latest version of the JDK development package:
$ dnf search jdk-devel
Last metadata expiration check performed 12:44:51 ago on Mon Aug 3 22:20:24 2015.
============================ N/S Matched: jdk-devel ============================
java-1.8.0-openjdk-devel.x86_64 : OpenJDK Development Environment
java-1.8.0-openjdk-devel-debug.x86_64 : OpenJDK Development Environment with
: full debug on
$ sudo dnf install java-1.8.0-openjdk-devel
First check if the Java JDK is installed correctly:
dpkg --list | grep -i jdk
If not, install the JDK:
Download the latest version of the JDK from Oracle: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
Extract it to the appropriate location in your machine. Get the extract location:
vi ~/.bashrc or vi ~./ bash_profile
JAVA_HOME=/home/user/installs/jdk1.7.0_40
PATH=$JAVA_HOME/bin
source ~/.bashrc or source ~/.bash_profile
After the installation you can check it:
java -version
which java
If all things are correct then the right the answer should be something like this:
java version "1.7.0_40"
Java(TM) SE Runtime Environment (build 1.7.0_40-b43)
Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode)
Append the following statement to studio.sh the file in android-studio/bin directory:
JAVA_HOME=/home/user/installs/jdk1.7.0_40
Finally start your Android Studio with the following command:
./studio.sh
The problem is a bug on Fedora 20. The bug is very odd: if I have Google Talk plugin installed then Eclipse crashes (https://bugs.eclipse.org/bugs/show_bug.cgi?id=334466). It's crazy for me. I thought that was Java version and with Java 6 my eclipse was still crashing. To solve this I should use gnome/GTK instead KDE. Now it works "well" (in gnome environment). Thanks for all answers.
I was facing similar problem on Windows 7 x64 professional edition. Please note following steps to fix this problem.
tools.jar is missing from required path if you are using jdk1.7 x64 bit version.
Please install x86 version of jdk1.7
Set JDK_HOME="C:\Program Files (x86)\Java\jdk1.7.0_67" and update path environment variable as path="C:\Program Files (x86)\Java\jdk1.7.0_67\bin"
Note: Linux put the proper path.
Launch 32 bit application from /android-studio\bin folder.
I tested and verified these steps on windows 7 with 32 bit jdk1.7
It's probably because you don't have jdk installed in your machine. I had exact same problem in first run. Open a terminal (CTRL+ALT+T) and type: sudo apt-get install openjdk-7-jdk
When done setup Java environment variable. Steps as follows:
sudo gedit /etc/environment
Either in the beginning or end of the file write: JAVA_HOME=/usr/lib/jvm/java-7-openjdk-i386 (location may vary depending on the installation of your Java)
export JAVA_HOME
save and exit editor.
Load the path variable again using the terminal: . /etc/environment
Couple of helpful links for further clarifications:
How to install JDK on Ubuntu (Linux)?
How to set JAVA_HOME for OpenJDK?
Hope this helps.
On Windows 7 just run the studio.bat file in your android-studio/bin folder with right click as an administrator. Now you get ask to import previous studio settings. Ignore this and on the next dialog you can specify the path to your jdk directory.
That's all.

I ran into this issue when I was referencing
[drive]:\Program Files\Java\jdk1.8.0_65
in my JAVA_HOME environment var instead of the Android Studio recommended
[drive]:\Program Files\Java\jdk1.7.0_79.
I am using the x64 version of the JDK on Windows 10 Pro.
From the Android Studio installation instructions.
Before you set up Android Studio, be sure you have installed JDK 6 or higher (the JRE alone is not sufficient)—JDK 7 is required when developing for Android 5.0 and higher. To check if you have JDK installed (and which version), open a terminal and type javac -version. If the JDK is not available or the version is lower than version 6, download the Java SE Development Kit 7
http://developer.android.com/sdk/installing/index.html?pkg=studio
You have 2 things you must check:
verify that /etc/environment file has the correct JAVA_HOME and PATH values referring to your Java installation directory.
verify that you have the correct Java version (maybe you are using a distribution of Linux which need a server version of Java) you may need this version like my case JRE for server.
On my Linux Mint 17.3 install, I found these instructions incredibly helpful.
The problem seems to boil down to the system's default Java being OpenJDK and Android Studio preferring Oracle's JDK. I actually did not perform the OpenJDK removal steps given in the tutorial, but only downloaded the Oracle JDK and set it as my system's default. Android Studio worked right away.
In case the linked page ever goes away, the steps I took were
Download Oracle JDK. Mine was version 1.7.0_79.
tar -zxvf jdk-7u79-linux-x64.tar.gz
sudo mkdir -p /opt/java
sudo mv jdk1.7.0_79 /opt/java
sudo update-alternatives --install "/usr/bin/java" "java" "/opt/java/jdk1.7.0_79/bin/java" 1
sudo update-alternatives --set java /opt/java/jdk1.7.0_25/bin/java
and
java -version
confirms the system is using Oracle's JDK, giving output like
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

Compile Android source on Ubuntu 12.04 cannot continue because of bad JDK version

I've been trying all day to compile the Android source code on my Ubuntu 12.04 64bit OS.
For some reason, I'm stuck on the phase of having the Sun/Oracle JDK 1.6 version installed. I've been trying many commands (and the official link of course) and I end up either having nothing, having JDK 1.7 or OpenJDK, or not having the jdk-tools.
What are the exact steps to successfully compile the code (or part of it) using JDK? I'm stuck at the phase of "make j4" on this link.
installing the proper java version(1.6) for android do the below
1) Installing JDK
Since Sun JDK is no longer in Ubuntu’s main package repository, we have to manually install it in ubuntu 12.04 from oracle website
Please go the below link and download the JDK
http://www.oracle.com/technetwork/java/javase/downloads/jdk6-downloads-1637591.html
Follow the below steps to install the java and configuring it for the usage
$ chmod +x jdk-6u33-linux-x64.bin
$ sudo ./jdk-6u33-linux-x64.bin
$ sudo mv jdk1.6.0_33 /usr/lib/jvm/
$ sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.6.0_33/bin/java 1
$ sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.6.0_33/bin/javac 1
$ sudo update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.6.0_33/bin/javaws 1
$ sudo update-alternatives --config java
$ sudo update-alternatives --config javac
$ sudo update-alternatives --config javaws
To verify the isntallation is proper do the belwo steps. It should now show that the Sun JDK is running instead of IcedTea
$ java -version
java version "1.6.0_33"
Java(TM) SE Runtime Environment (build 1.6.0_33-b04)
Java HotSpot(TM) 64-Bit Server VM (build 20.8-b03, mixed mode)
For compiling android on ubuntu 12.04 and installing the proper java version

In Ubuntu, when you download the jdk (32-bit version if it is for android programming, and in my opinion better the tar.gz than the .rpm one) it is important to 'install' and also to export using the commands you can see in the page of Oracle if I'm not wrong. You also need to go to your editor (Eclipse, Netbeans or which one?) and add the new Java platform to make sure you are using the version of the JDK you want to.To export means that you can compile the project when you want to.If not,you have to go to the java directory and inside the /bin folder do the command (probably with sudo at the beginning) to compile your project.
P.S.: You can find how to export here
I got this same problem. Some people reporting even JDK SE will see errors.
Another work-around is modifying two lines of source code, see here:
