Add android-studio/bin/ to PATH environmental variable

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.
