I've been pretty happy with keepass2android's keyboard integration. It avoids the clipboard entirely and helps autoselect the right password and username if you let it. It also supports using a HOTP NFC token in conjunction with the master password. I know it doesn't add that much security since a determined attacker could still brute force the OTP with the way it works but it keeps out the casual attacker that's not that savvy.
