/home/tnt/.bash_profile  
/home/tnt/.bashrc
/home/tnt/.profile  
/root/.bash_profile  
/root/.bashrc
/root/.profile 

but it wont works

Answer 1

I don't think its necessary to add everything into path.Just add the JAVA_HOME , ANDROID_HOME and ANT_HOME to path and point out the corresponding bin directory as:

For android studio

add this into your ~/.bashrc file:

1.export ANDROID_HOME=/path/to/android/studio
2.export PATH=$PATH:$ANDROID_HOME/bin

you can do the same for Ant.

For java jdk

add this into your /etc/profile file:

1.JAVA_HOME=/path/to/jdk
2.JRE_HOME=$JAVA_HOME/jre
3.PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin
4.export JAVA_HOME
5.export JRE_HOME
6.export PATH

Now in your terminal, type echo $PATH and make sure all the environment variables are added to the PATH!

Answer 2

You should edit /etc/sudoers with

sudo visudo

At the end of the file enter:

Defaults    env_keep +="ANDROID_HOME"
