In a database might be a good solution. The notepad tutorial is a decent introduction to programming with databases in an Android app.

Also, it's worth spending the time necessary to read and become familiar with the topics covered in http://developer.android.com/guide/topics/data/data-storage.html


Use this to check for connection:

public boolean isOnline() {
 ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
 return cm.getActiveNetworkInfo().isConnectedOrConnecting();

}

On storing data to SQLite check this tutorial:

I approve Mark Mooibroek response and advise to use some DB helper instead of raw SQLite, as it needs a lot of boilerplate code. Last time I was glad with using Realm database library. It's faster than SQLite in terms of both efficiency and coding time.
