<a href="http://www.activerecordjs.org" rel="nofollow noreferrer">ActiveRecordJS</a> from Aptana is a Javascript ORM that should run on the gPhone. It is designed to work with Jaxer and Gears. When you user the Jaxer Adapters, you can connect to SQLLite.

UPDATE: I don't think I made it clear, but ActiveRecordJS is an ORM that runs client side, which could be an advantage to you on the gPhone.

I have developed my own implementation of the JPA ORM for Android. It is not yet fully feature complete, but you can annotate class with the @Entity, @Id, @Column annotations and you get JPA entities that can be stored and retrieved from the SQLite database. It needs some more features &amp; cleanup before I'll post it to the public, but if there is enough interest it might accelerate my effort.

NeoDatis and db4o are really similar, so I would like some advice to choose the best one. Is someone using one of them on his project ? I'll use it for free and paid app, but it seems that the two haven't any license limitation for Android.

There is a benchmark <a href="http://sourceforge.net/projects/neodatis-odb/files/NeoDatis%20ODB%20Performance/NeoDatis%201.9/PolePosition_NeoDatis-1.9.pdf/download" rel="nofollow noreferrer">here</a> that seems to say that NeoDatis is faster than db4o, but I don't know if we can base my opinion on this.

Anyone working on the Android ('gPhone') have or know of a place where I can find a good ORM tool for it? The code is written in Java, and the database is SQLite. What I would like to find is a tool that given the object definition, can auto-generate the tables and the CRUD functions (that would be awesome), or, barring that, a tool that can take the table definition, the object definition, and auto-generate the CRUD functionality. The rub is that all of this must happen within the Android framework, which has its own conventions as to how database access works.

Any good ORM tools for Android development?
