使用Android NFC向Java Card发送超过261个字节(Send more than 261 bytes to Java Card with Android NFC)

 我想通过NFC（Class IsoDep ）将长度为1699字节的APDU发送到Java Card智能卡。 我收到了错误 
 
 
 
 java.io.IOException：收发长度超过支持的最大值 
 
 
 我的手机是三星Galaxy S7。 
 
 我在卡片上的小程序中使用了扩展长度。 我已经确认该卡支持延长长度。 我通过pyapdutool测试了这个，通过向卡发送4000字节的APDU。 
 
 我发现当我编写这段代码时，结果是false ： 
 
final Tag t = (Tag) tag;
myTag = IsoDep.get(t);
boolean result = myTag.isExtendedLengthApduSupported();
 
 我的清单中有这个： 
 
<activity
        android:name=".test"
        android:label="@string/title_test"
        android:launchMode="singleTop"
        android:theme="@style/AppTheme.NoActionBar" >
    <action android:name="android.nfc.action.TAG_DISCOVERED" />
    <category android:name="android.intent.category.DEFAULT" />
    <intent-filter>
        <action android:name="android.nfc.action.NDEF_DISCOVERED" />
    </intent-filter>
</activity>
 
 如何通过Android NFC发送1699字节（或任何长度大于261字节）的APDU？ 

I want to send an APDU with a length of 1699 bytes via NFC (class IsoDep) to a Java Card smartcard. I get the error
 
 
 
java.io.IOException: Transceive length exceeds supported maximum
 
 
My phone is a Samsung Galaxy S7.
 
I use extended-length in my applet on the card. I have verified that the card supports extended length. I tested this via pyapdutool by sending an APDU with 4000 bytes to the card.
 
I found that when I write this code, the result is false:
 
final Tag t = (Tag) tag;
myTag = IsoDep.get(t);
boolean result = myTag.isExtendedLengthApduSupported();
 
I have this in my manifest:
 
<activity
        android:name=".test"
        android:label="@string/title_test"
        android:launchMode="singleTop"
        android:theme="@style/AppTheme.NoActionBar" >
    <action android:name="android.nfc.action.TAG_DISCOVERED" />
    <category android:name="android.intent.category.DEFAULT" />
    <intent-filter>
        <action android:name="android.nfc.action.NDEF_DISCOVERED" />
    </intent-filter>
</activity>
 
How can I send an APDU with 1699 bytes (or any length greater than 261 bytes) through Android NFC?
