In this App we will be using Sqlite, Http petitions and SharedPreferences.
SQLite database management classes that an application would use to manage its own private database. Applications use these classes to manage private databases. If creating a content provider, you will probably have to use these classes to create and manage your own database to store content.
In order to make Http request such as Get or Put we need to create a Class that extends AsyncTask. Because its necessary in order to not freeze the UI.
We used sharedPreferences in order to save some basic information about our state, such as the question we are in or the money accumulated, to be able to use it in case screen rotation of our device (land to portrait ,or vicebersa).
If you have any question or any problem feel free to contact me =D.
