編輯：請閱讀完整的交代NFCA收發命令文件NFC-A（ISO 14443-3A）

我在哪裏可以找到android.nfc.tech.NfcA使用的文件提交henrycjc和我兩個答案？

/** 
* Provides access to NFC-A (ISO 14443-3A) properties and I/O operations on a {@link Tag}. 
* 
* <p>Acquire a {@link NfcA} object using {@link #get}. 
* <p>The primary NFC-A I/O operation is {@link #transceive}. Applications must 
* implement their own protocol stack on top of {@link #transceive}. 
* 
* <p class="note"><strong>Note:</strong> Methods that perform I/O operations 
* require the {@link android.Manifest.permission#NFC} permission. 
*/ 
public byte[] transceive(byte[] data) throws IOException

我不太清楚tranceive語法是如何工作的，我目前的理解是，在byte[]第一byte是命令，我想找到在哪裏可以找到這些列表。我試圖自己查看，但空手而來。

卡我試圖與互動： （轉儲圖片） Image of dump

的文檔可以在Android官方文檔中找到提交henrycjc和我兩個答案。具體來說，收發是在這裏：

https://developer.android.com/reference/android/nfc/tech/NfcA.html#transceive(byte[])

至於你的其他問題，我想看看這些以前的SO問題：

Android nfcA.connect(), nfcA.transceive(), nfcA.setTimeout() and nfcA.getMaxTransceiveLength()

How send NfcA command to the MIFARE card?

不錯。出於興趣，你是否因爲Android 7.0。*格式化NDEF的錯誤？ – henrycjc

我正在寫一個應用程序，可以寫一個鏈接到一個標籤，但我不希望我的用戶不得不購買特定的標籤，因爲我不得不使用'android.nfc.tech.NfcA'。我設法使用以下方式將數據寫入特定位置：D。 –

另外，是的。我也遇到了這個錯誤，但認爲我做錯了。 [看起來像更多的用戶遇到這個問題]（https://code.google.com/p/android/issues/detail?id=227165）... –
