I'm installing android sdk on ubuntu 13.10 using this guide http://tutorialforlinux.com/2013/11/25/how-to-install-android-sdk-on-ubuntu-13-10-saucy-easy-visual-guide/
I'm stuck on updating android sdk tool and api's step 7. When I
cd /opt/android-sdk* the command works but when I enter
sudo su -c "tools/android" command I get bash:
tools/android: permission denied
What am I doing wrong and yes I've seen the guide to install open sdk here but I don't want to install the open sdk I need the normal java version.
