Hi Xiaoliang,
We know this is a little annoying, we are thinking about some improvements
for future Android releases, so that you only need to enable foreground
dispatch for all activities in an application, and not for every activity.
For now you have to enable it in every activity.

Correct, we do not support Card Emulation in the SDK. It's actually very
