Title Body

I am newbie in Android NFC API. Currently, I have a NFC tag, I am making an Android app to read data from it. My simple App is launched when my phone get closer enough to the NFC Tag. But I have no idea how to read the data inside the NFC Tag. The tag uses IsoDep technology. My current code: @Override protected void onResume (){ super.onResume(); Intent intent = getIntent(); Tag tag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG); IsoDep isoDep = IsoDep.get(tag); // How to read data from IsoDep instance? I googled on internet, I notice people are sending commands to IsoDep to get response from NFC Tag, I suppose from the response, we can parse the data in the tag, I saw people doing this: //What is the 'command' ? How to define the command? //e.g.: byte command = (byte) 0x6A isoDep.transceive(command) But, the command is just a byte , as a newbie, it is too difficult to understand what is happening. I have no idea how to define the command to read data? Anyone can explain to me? or is there a document I can learn about the command? Generally, I need some guidance on how to define commands & how to parse data from response, I would like to read the data stored in the Tag & show the data in String format in UI element (e.g. TextView ). AND I have no problem with those configurations(e.g. AnroidManifest.xml), please don't guide me on how to configure :)
