Add android-studio/bin/ to PATH environmental variable

Question

Recently I installed Android Studio. Now I want to add android-studio/bin/ persistently to PATH environmental variable as Session-wide environment variables and not as System-wide environment variables. To do that I tried to edit ~/.profile as described here. So I have these at the end of ~/.profile:

if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH:/usr/local/Android/android-studio/bin"
fi

Then I re-login to initialize the variable. But when I run studio.sh in terminal, I get this:

studio.sh: command not found

Here are results of $PATH and echo $PATH:

$ $PATH 
bash: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:
No such file or directory 
$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games

Also I'm sure that ~/.bash_profile and ~/.bash_login do not exist. Now what cause the problem and how I can solve that?

Edit:

I change end of ~/.profile to this, but it does not work:

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
    PATH="$PATH:/usr/local/Android/android-studio/bin"
fi

Solution

It looks like you edited this code snippet:

if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

which is included in ~/.profile by default.

The answer which lead you to do so is confusing IMNSHO.

I'd suggest that you change that code back to what it looked like before, and instead add a new line underneath it:

if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

PATH="$PATH:/usr/local/Android/android-studio/bin"

Then, next time you log in, PATH ought to be altered, whether $HOME/bin exists or not.

Why I have to add that to ~/.bashrc when I did not that here:help.ubuntu.com/community/EnvironmentVariables. Also how I can check the existence of $HOME/bin?

[Gunnar Hjalmarsson]

@hasanghaforian: That recommendation makes no sense to me either.

Because ~/.bashrc always gets run when you enter Terminal. It's just another check to ensure that it happens. See edit for checking existence @hasanghaforian

[Gunnar Hjalmarsson]

If you use ~/.profile to edit PATH, which is an environmental variable, the new value is available in the whole session, whether you use the terminal or not. If you do it right, you don't need "another check". ;)

[hasanghaforian]

I tried that, but it does not work. I edited question, please see it again.

[Gunnar Hjalmarsson]

@hasanghaforian: Ok, I edited my answer too to clarify.

[hasanghaforian]

Thank you for your attention and help! But if I would to add another path, I have to add another line?

[Gunnar Hjalmarsson]

@hasanghaforian: Not necessarily. The point is that it shouldn't be between if and fi. As long as you keep it where it is now, you can say PATH="$PATH:/some/directory:/some/other/directory"

[Daniel]

Well, I've run into cases where ~/.profile doesn't get processed at all, so I don't trust it as much...

[Nick Pineda]

Once the path what is the command to execute the program globally?

[Gunnar Hjalmarsson]

@NickPineda: studio.sh, I suppose. (I don't use the program myself.)
