NullPointerException when launching example app

[keianhzo]

Hi,

First of all thanks so much for this project, I think is really important at the moment as there is not a secure way to store critical information in an android device, so this project fills an important gap.

At the moment the project throws a NullPointerException when executing as the EventDataSQLHelper object is still null when the getWritableDatabase is called on him in the onCreate method. Just that!

Thanks so much for your hard work.

This has been fixed. The example code now properly functions.
