Eu sou muito novo para o Android.
Eu quero identificar qual é o dispositivo NFC ou dispositivo habilitado para NFC.
Por favor, forneça a diferença entre o modo NFC:
- ler / gravar
- comunicação p2p
I am very new to Android.
I want to identify which one is enabled NFC tag or NFC-enabled device.
Please provide the difference between NFC mode:
I'm not sure if you have a first question, or if I understand your first question. But, if you are looking for an app to read NFC tags, just search for "check nfc" in Google Play. There are a lot of apps there.
If you want to enable the NFC on a device, go to
Settings > Wireless & Networks > More... > NFC. This is also how you check if the device can read NFC.
To answer your second question, please look at conor's answer in this question: Is it possible to use Android Beam between an android device and another NFC device?
