Android: Display alert dialogs

It is useful to display confirmation dialogs in your app to prevent accidental presses.

There is an inbuilt feature to do that, and its called the AlertDialog Builder.

This may look a bit messy, but its all chained together. You can split it up into separate calls if you want to make it look a bit neater.
