Have you done Android compilation with Coinami?
https://bitcointalk.org/index.php?topic=713649.0The issue I have with an android wallet would be holding the entire chain on your phone so over time it would consume a fair amount of resources. Coinami is open source and uses an electrum server to create a lightweight client. Is this something that you think you would be able to do?
If that is not possible then just the standard client would be fine, I have BTC available for the work.
I only offer the standard client for now, I will offer a solution similar to coinomi soon, including iOS support.
With modern phones, storing the chain is not really a big deal, also as shown in the pie chart posted before, the ressources usage is very reasonable, but the standard wallet offers some features coinomi doesn't like wallet encryption, backup and more.
I have tested this wallet with coins that are more than a year old and it works fine. Thanks!
