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。

$cd /opt/Java
$sudo unzip ./下载包名
add environment path to file:
$sudo gedit /etc/profile
adding the following content in the end :
export ANDROID_HOME=/opt/Java/android-sdk-linux
export PATH=$ANDROID_HOME/tools:$PATH
