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.
