In general, I think it would be inappropriate to have a full-featured ORM running on Android. If you have lots of complex data to persist, it probably would be best to handle it server-side. If you have only a little complex data to persist, you probably can load it into RAM in one go so you don't need the full features of an ORM. If you want a simple mapping of Java objects to SQLite tables for Android apps, I'll toot my own horn here and suggest my (free, open-source, and slightly immature) sqlitegen (http://code.google.com/p/sqlitegen), which is an Eclipse plugin for Android that generates database code at compile time from annotated Java interfaces, where the generated code handles CRUD functions as well as Android-specific stuff like going to/from a ContentValues. Since sqlitegen does all its stuff at compile time, the apps using it are pretty efficient at runtime. If you search around, there are a few other lightweight tools for persisting objects on Android. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
