I have altered my ~/.profile file by adding the following:

PATH="/user/share/android-sdk-linux/tools:$PATH"

I then log off and log in again, but the path is not added to the $PATH environment variable. I am checking in terminal:

echo $PATH

/usr/share/android-sdk-linux/tools:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/lib/jvm/jdk1.7.0_17/bin

Please advise

Edit

I have even tried:

PATH=$PATH:/usr/share/android-sdk-linux/tools

EXPORT PATH

No luck here either.

~/.profile:

 # ~/.profile: executed by the command interpreter for login shells.

# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login

# exists.

# see /usr/share/doc/bash/examples/startup-files for examples.

# the files are located in the bash-doc package.



# the default umask is set in /etc/profile; for setting the umask

# for ssh logins, install and configure the libpam-umask package.

#umask 022



# if running bash

if [ -n "$BASH_VERSION" ]; then

    # include .bashrc if it exists

    if [ -f "$HOME/.bashrc" ]; then

    . "$HOME/.bashrc"

    fi

fi



# set PATH so it includes user's private bin if it exists

if [ -d "$HOME/bin" ] ; then

    PATH="$HOME/bin:$PATH"

fi



# set path to android

# PATH = $PATH:/usr/share/android-sdk-linux/tools

# EXPORT PATH



PATH="/usr/share/android-sdk-linux/tools:$PATH"

Adding to ~/.bachrc or /etc/environment:

PATH="/usr/share/android-sdk-linux/tools:$PATH"

works, but why not ~/.profile?
