In this tutorial I will show you how you can connect to Raspberry Pi 2 Model B using ssh. The difficult part about using ssh via Android is that many Android devices' software keyboard doesn't have the "Ctrl" key. The "Ctrl" key is essential in quitting programs, and many other things.
The solution to that is simple.
1. Download an app called Keyboard with Ctrl key here.
2. Setup so that you can input using Keyboard with Ctrl key by making that the default input method.
3. Download an app called SSH Client by Anstudios Ltd here.
4. connect to Raspberry pi 2 via SSH Client like this: email@example.com (whatever the Raspberry Pi 2's IP address is)
Wallah! You're done! :) Happy hacking!
