I installed aide from playstore and copied the code from google to test the HostApduService. My app is shown under Tapp and Pay but if I send a CAPDU with my identive cloud 4700f reader my phone LG G2 (android 4.4.2) is not responding anything. My reader is blinking and pcsc tells card is connected. It seems that the service is never started but I don't know why. Does anybody had the same problem and hopefully a solution?
There seems to be a general problem with Android HCE on the LG G2 (see this blog). So I would assume that HCE is not avaliable on the G2 with Android 4.4.2 but will be part of the next update.
