Hi Paramesh,
welcome to the mailing list! Good to know that you are kicking off the
work on bringing Android to Genode.

I am not proficient with the ART runtime. So I can only give general
advice. If I pursued this line of work, I would start as follows:
1. Get accommodated with ART, compiling and running it on Linux with
small examples, and investigate its library dependencies. Also, I
would try to find out the feature set required from the host OS.
I.e., does it depend on fork/exeve, how does it communicate with
other parts of the system (Unix domain sockets, binder, etc.)?
Look if those code portions are somehow abstracted so that they
can eventually be replaced by Genode-specific code. I would also
try to disable all optional features like optimizations. The
goal should be to get a version of the runtime that is as simple
as possible.
2. Port the library dependencies to Genode following this guide:
http://genode.org/documentation/developer-resources/porting
While porting the libraries, I would stick with the base-linux
platform, which enables you to use GDB for debugging. So the
development can happen at a fast pace.
3. Once all libraries needed by ART are ported, it is time to
port ART itself. The steps outlined in the above linked porting
guide might be very helpful. I would keep using base-linux at this
point. The goal should be to run a minimal-complexity example
(like a hello-world program) using a run script.
4. Now that a simple example is running on base-linux, proceed to
run the same scenario on one of the microkernels. I think that
when you managed to reach this stage, the further steps will
become apparent automatically.
Happy hacking!
Norman
