how to build a android environment in ubuntu 15.10

As we know, the android development environment need four part: JDK SDK IDE ADT.

Problems:

there are JDK versions from different companise. Previous, I run the command:

$sudo apt-get install openjdk-7-jdk 

to install openjdk released by ubuntu ，and then，installing  the eclipse IDE ，

$sudo apt-get install eclipse-platform

Coming next is installing the SDK from official website，all is well，

the troublesome occurred when I went to installed ADT and created a new project.

so, I don't support to use openjdk.

Solution:

1、The Jdk installed from oracle：

$sudo add-apt-repository ppa:webupd8team/java
$sudo apt-get update
$sudo apt-get install oracle-java8-installer
and don't cofigue any environment variables。

$sudo unzip ./下载包名

add environment path to file:

$sudo gedit /etc/profile

adding  the following content in the end :

export ANDROID_HOME=/opt/Java/android-sdk-linux
