Ubuntu11.04 Android Development Environment Construction

1. Install JDK.

Ubuntu11.04 does not own JDK source, so you cannot install it directly through sudo apt-Get install sun-java6-jdk

(1) first, you need to add the Java SDK source, which can be implemented through the following command:

Sudo add-Apt-repository PPA: ferramrobert to/Java

(2) install the add-Apt-repository command

Sudo apt-Get install Python-software-Properties

(3) update source

Sudo apt-Get update

(4) install JDK

Sudo apt-Get install sun-java6-jdk

2. Configure Java environment variables

(1) Configure environment variables after installation
Sudo gedit/etc/environment
(2) Open the environment variable file and add the following code:
Classpath =.:/usr/lib/JVM/Java-6-sun/lib
Java_home =/usr/lib/JVM/Java-6-sun
Note: Java-6-Sun is the JDK folder, which may be different from this. check the folder name installed on your machine in/usr/lib/JVM.
(3) Open the JVM virtual machine configuration file.
Sudo gedit/etc/JVM Add the following code to the top:/usr/lib/JVM/Java-6-sun

3. Install eclipse

(1) download and install eclipse:

Http://www.eclipse.org/downloads/

Download the 32-bit or 64-bit Eclipse IDE for Java developers based on your Ubuntu version.
