The Quark hashing functions were found and adapted for a fork of the Bitcoin Wallet 3.31.

This app should be available soon for beta testing.

A forum is being planned as a resource to help android wallet developers.

The forum has been established here.

A request was made for a Quark wallet.  After that we considered a SecureCoin wallet.  Both use the same six hash functions (blake*, bmw, groestl, jh, keccak* (SHA-3) and skein*).  Currently only three have existing Java code as far as we can tell.  If anyone knows about the other three hash functions, let us know.  At this point a Quark or SecureCoin Wallet is not possible.
