Question

我使用chariot solutions phonegap plugin编写NFC标签，但我不确定如何使用phonegap插件编写Android Application Record。

以下是我编写NDEF记录的代码：

nfc.addNdefListener( function(nfcEvent) {

    var tag = nfcEvent.tag, ndefMessage = tag.ndefMessage;

    if (tag.isWritable && tag.canMakeReadOnly) {
        log( JSON.stringify( tag ) );

        var type = "application/com.example.name",
        id = 1234,
        payload = nfc.stringToBytes( JSON.stringify( { payloadID : 1234 } ) ),
        record = ndef.record( ndef.TNF_MIME_MEDIA, type, id, payload );

        var message = [ record ];

        nfc.write( message, function() {
            alert( "Successfully written to NFC Tag!" )
        }, function() {
            alert( "Failed to write to NFC Tag!" )
        } );
    }

}, function() { // success callback
    log( "Waiting for NDEF tag" );
}, function(error) { // error callback
    alert( "Error adding NDEF listener " + JSON.stringify( error ) );
} );

如何使用phonegap编写Android应用程序记录（AAR）？

答案是根据spec found here

写一个TNF_EXTERNAL_TYPE记录

nfc.addNdefListener( function(nfcEvent) {

    var tag = nfcEvent.tag, ndefMessage = tag.ndefMessage;

    if (tag.isWritable && tag.canMakeReadOnly) {
        log( JSON.stringify( tag ) );

        var type = "application/com.example.name",
        id = 1234,
        payload = nfc.stringToBytes( JSON.stringify( { payloadID : 1234 } ) ),
        mime = ndef.record( ndef.TNF_MIME_MEDIA, type, id, payload );

        var type = "android.com:pkg",
        id = "",
        payload = nfc.stringToBytes( "com.example.name" ),
        aar = ndef.record( ndef.TNF_EXTERNAL_TYPE, type, id, payload);

        var message = [ mime, aar ];

        nfc.write( message, function() {
            alert( "Successfully written to NFC Tag!" )
        }, function() {
            alert( "Failed to write to NFC Tag!" )
        } );
    }

}, function() { // success callback
    log( "Waiting for NDEF tag" );
}, function(error) { // error callback
    alert( "Error adding NDEF listener " + JSON.stringify( error ) );
} );
