help with adding keyrings on android!!

there is a service i want to access on an android device that has an encrypted leaseset and i cant figure out how to add the key to it. the app from geti2p doesnt provide an interface like the pc java one does and i2pd provides a web interface but no keyring config section.... are there any other i2p clients/routers on android? any way to run the jar version on there?? any help would be very appreciated >.<!!
