Hi to all the Community I am experiencing an uncommon problem with a card emulation android app. When receiving an APDU from a card reader, the processCommandApdu() method extended from HostApduService gives a processing time of less than 1 ms (measured with System.nanotime(), but the processing time reported by the host application / simulator adds about 30 ms to that time, so the APDU is processed by the host PC in about 30 ms. The app is a very simple skeleton with just the minimum features and code as described by Google, and the response is hardcoded. Does anyone have and idea of the possible reason for this behavior? Many thanks in advance. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
