9 years ago Can you see if you can get it to crash with this example? https://github.com/don/phonegap-nfc-issue-150
Can you try your app on other phones? Does it matter how fast or slow you write to the tags?

9 years ago Thx for you quick response.
No, your example runs without any error. Yes, i tried it also on a Sony device.
I found a workaround, so it doesn't crash anymore. I parse the event to a function. Like in your examples.
Controller Code:
$scope.writeNFC3= function(){
data = ["1234557","Data","setLed(2)","LED 400,400"];
$nfcMode.setData(data);
$nfcMode.setMode(0);
$nfc.registerHandler().then(function(event){
$nfc.actionTag(event).then(function(res)
{alert("Event result: "+res);});
});
Factory Code:
.factory('$nfc', [ '$q','$nfcMode' ,function ($q,$nfcMode) {
return {
actionTag: function(tagDiscover)
{
var deferred = $q.defer();
switch($nfcMode.getMode())
{
case 0: //schreiben
var data = $nfcMode.getData();
var message = [];
console.log("Length:" + data.length);
for(var i = 0; i < data.length;i++)
{
message.push(ndef.textRecord(data[i]))
// console.log(JSON.stringify(message))
}
//console.log(JSON.stringify(message));
nfc.write(message,
function () {
console.log("Wrote data to tag.");
deferred.resolve("okay");
},
function (reason) {
console.log("NFC Haud ned: "+reason);
deferred.resolve(reason);
}
);
break;
case 1:
var message = tagDiscover.tag.ndefMessage[0]["payload"];
console.log("TAG Complete:"+JSON.stringify(tagDiscover.tag));
console.log("DATA:" + nfc.bytesToString(message ));
deferred.resolve(nfc.bytesToString(message));
break;
case 2:
var message = tagDiscover.tag.ndefMessage[$nfcMode.getIndex()]["payload"];
console.log("TAG Complete:"+JSON.stringify(tagDiscover.tag));
console.log("DATA:" + nfc.bytesToString(message ));
deferred.resolve(nfc.bytesToString(message));
break;
default:
console.log("Default case");
}
return deferred.promise;
},
registerHandler: function() {
var deferred = $q.defer();
nfc.addNdefListener(function(tagDiscover)
{
console.log("Event recieved");
return deferred.resolve(tagDiscover);
},
function()
{
$nfcMode.setNFC(1);
},
function()
{
$nfcMode.setNFC(0);
});
return deferred.promise;
}
}}])
I guess if you use the event in the addNdefListener function causes the error.
Now the App runs perfect.

4 years ago Hi, I'm having the same issue. As soon as I try to write or read the second time the app suddenly crashes. I found this error in logcat:

Thanks in advance for helping!

Hey @Oussie00, any news?
Hey, thx for this great plugin!
I have a strange error, everytime my Cordova + Ionic app crashes after the third write. Reading works perfect 100 times. The data is written onto the tag but the app crashes afterwards. My device is a Galaxy Nexus with Android 4.3. The app is build with NFC plugin version 0.6.0 and Cordova is version 4.0.0
Im getting this error log after executing write to tag the third time: D/NfcPlugin( 9045): execute writeTag W/dalvikvm( 9045): threadid=24: thread exiting with uncaught exception (group=0x417ba700) E/AndroidRuntime( 9045): FATAL EXCEPTION: pool-1-thread-3 E/AndroidRuntime( 9045): java.lang.IllegalStateException: Close other technology first!

Any idea??
Thx for your help!
