Android : How To Change Nfc Protocol Priority?

I have my own Android app (App A) which reads and writes NFC tags and ISO-14443 Type A tags. It works well on many Android devices. I want to give the role of ISO-14443 tag to my N

Solution 1:

The solution is only available on Android 4.4 Kitkat (which is available for the Nexus 7). You need to enable so-called "reader mode", which is designed to handle this particular situation, using enableReaderMode().

In this mode the NFC controller will only act as an NFC tag reader/writer, thus disabling any peer-to-peer (Android Beam) and card-emulation modes of the NFC adapter on this device. [...] For interacting with tags that are emulated on another Android device using Android's host-based card-emulation, the recommended flags are FLAG_READER_NFC_A and FLAG_READER_SKIP_NDEF_CHECK.
