I have gone through Siminov Android ORM Framework, it is open source framework with proper user guide and documentation. It is easily configurable, handle application deployment, support multiple schemas and many more. I found it very useful and easy to use.Good thing is same available on other platforms also e.g iOS, Windows 8. I suggest you to try this, you will definitely find it useful and this ORM may solve your problems.
