1、Installing Java

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

After that

  sudo apt-get install oracle-java8-set-default

2、Installing Android Studio

   (1) Download Android Studio from here or here，use All Android Studio Packages

  (2) Extract the archive file into an appropriate location for your applications, eg: /opt. Use the filename of your downloaded archive, in my example android-studio-ide-143.2739321-linux.zip

　　sudo unzip android-studio-ide-141.2178183-linux.zip -d /opt

  (3) To launch Android Studio, navigate to the /opt/android-studio/bin directory in a terminal and execute ./studio.sh. Or use a desktop file, see below.

You may want to add /opt/android-studio/bin to your PATH environmental variable so that you can start Android Studio from any directory.

3、Create a desktop file

gedit ~/.local/share/applications/android-studio.desktop

and add the lines below

　　[Desktop Entry]
　　Version=1.0
　　Type=Application
　　Name=Android Studio
　　Exec="/opt/android-studio/bin/studio.sh" %f
　　Icon=/opt/android-studio/bin/studio.png
　　Categories=Development;IDE;
　　Terminal=false
　　StartupNotify=true
　　StartupWMClass=android-studio

4、Installing Android SDK

use Android SDK manager or download from here

5、Add adb PATH

(1) sudo gedit ~/.bashrc

　　add this to the file

　　# Android SDK
　　export ANDROID_SDK_HOME=<your sdk path>
　　PATH=$PATH:$ANDROID_SDK_HOME/tools
　　PATH=$PATH:$ANDROID_SDK_HOME/platform-tools

and then

　　source ~/.bashrc 　　

(2) cd /usr/bin

　　sudo ln -s <your adb path>

(3) adb devices

　　if you get like this:　　

　　List of devices attached
　　0123456789ABCDEF no permissions

　　then you should just try this:

　　sudo adb kill-server

　　and then

　　sudo adb start-server

　　if you still get like this:

　　List of devices attached
　　0123456789ABCDEF unauthorized

　　maybe you should open USB debug on your phone
