Almost every application needs to store data — e.g. for saving user preferences, highscores or login data. This module explains the concepts behind the record stores, the only way to save data that is included in the MIDP specification and therefore supported on all phones. Data access can be handled conveniently using the DataInputStream and DataOutputStream-classes.This module also covers how to distribute your applications using different project configurations in NetBeans; a process which can involve pre-processing, selective resource inclusion as well as obfuscation. As mobile phones are available on a global market, localization is also a very important aspect. The challenge involves extending the game from the last course so that the game can save the highscore and can be deployed on phones with different screen sizes using specialized graphics.
