“One App” Android System

Question

I created an Android app which communicates via USART with a µC in order to evaluate data. My co-workers and customers should use the tablet for only this purpose now. Is there any possibility to "hide" the Android OS or making it inaccessible?

Devices are rooted and I am willing to build custom ROMs (even though I do not have any experience with that yet). Are there any approaches available that I do not have to start from scratch?

Many thanks for your help.

Well. That what I'm trying to do !

The first thing I tried was to start the app just after the boot of the device (Quite easy with this ).

Then, I get Android source code, and I hide the bottom bar using this code

The problem is, if your application is not stable ... you'll have some problem.

If you want to modify Android source code, the developper doc contains a very good tutorial to start !
