Compile Android 4.0.3 or more Jelly Bean on Ubuntu11.04_x64

1.Wrong Java Version

I have the Java 6 OpenJDK, version 1.6.0_24. This meets the android Java requirement for 1.6.0, but I found (later in the build process) that Android really needs to be built by Sun’s Java SDK. In the meantime, the _24 suffix doesn’t check out in Android’s makefile, which produces the error You are attempting to build with the incorrect version of java before exiting:


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

************************************************************
build/core/main.mk:131: *** stop. Stop.
Commenting out the $(error stop) statement from build/core/main.mk on line 131 will allow compilation to proceed:

131
132
# $(error stop)
endif
make will display the error message, but continue compiling. However, compiling with OpenJDK will probably create problems later in the build process (in out/target/common/obj/APPS/CtsVerifier_intermediates/classes-full-debug.jar). To fix the problems, Sun’s Java SDK will need to be installed.

2.Installing the Sun Java 6 JDK in Ubuntu 12.04

To fix the make: *** [out/target/common/obj/APPS/CtsVerifier_intermediates/classes-full-debug.jar] Error 41, get the most recent Sun JDK from here. Once you’ve downloaded it, install it and run update-alternatives so your system uses the Sun JDK:

$ chmod +x jdk-6u33-linux-x64.bin
$ sudo ./jdk-6u33-linux-x64.bin
$ sudo mv jdk1.6.0_32 /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 that the installation was successful, check Java’s version. 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)
To revert the changes after Android has been compiled, run update-alternatives to switch back to OpenJDK.
