i want to use usb Host communicating with smart card on android pad

but why do i get java.lang.NoClassDefFoundError: javax.smartcardio.TerminalFactory

i already import......

and i don't know how to package this lib into app

Could you share us your runtime? You may be on an older 64 bit runtime. `smartcardio` is in the `javax` tree, which means it is an optional package. JRE's are not required to implement it. — Maarten Bodewes, Oct 18 '14 at 00:35
i can run it on java project,but android project can not run on my pad/phone — Chuang come fromTaiwan, Oct 20 '14 at 08:54

When you did the development the required jar which contains

javax.smartcardio.TerminalFactory

is in the classpath.

But when you did installation/deployment/packaging, did you ensure that the required jar is also packaged along with app.
