问题 I'm developing with the Open Mobile API but so far haven't found a list of devices that support the API by default (by default being using the OEM ROM). I realise that since API level 21, Android telephony supports sending APDUs via basic and logical channels dirctly through the TelephonyManager. But I'd like to know about devices running pre-API level 21 too. So, has a list already been compiled of devices with built-in support or is there a way to find out for myself? 回答1: I'm not aware of

问题 I understand that to access SIM/eSE from an Android app we need to install Open Mobile API addon on Android Studio. However, is it true that it will not work on all NFC phones?
