Hi All, I have some problem when signing app, i'm very new to things like public key, private key, etc.... I try to build my project using ant, but always failed in signing part (debug.keystore), when i try to build using 'ant release' command, it was successfull but we still need jarsigner to sign our app. Can anyone give some simple example from start to finish, the signing process. I really appreciate that. Thanks.
