Setting up AWS IOT Core JITR process on Android

I need to set up a JITR (Just in time registration) process to AWS IOT core for my Android Application using Android AWS IOT SDK. My implementation is done referring this . However, When trying to create a thing after creating a fresh X.509 certificate (On the first connection attempt), Even though the certificate is created on the server, the Server returns errors regarding "unmatched signatures and an empty template body".
This is my current sample implementation,
public class MainActivity extends AppCompatActivity {
private boolean thingExist;
private String certificateARN;
// IoT endpoint
// AWS Iot CLI describe-endpoint call returns: XXXXXXXXXX.iot.<region>.amazonaws.com
private static final String CUSTOMER_SPECIFIC_ENDPOINT = "";
// Cognito pool ID. For this app, pool needs to be unauthenticated pool with
// AWS IoT permissions.
private static final String COGNITO_POOL_ID = "";
// Name of the AWS IoT policy to attach to a newly created certificate
private static final String AWS_IOT_POLICY_NAME = "";
// Region of AWS IoT
private static final Regions MY_REGION = Regions.US_EAST_2;
// Filename of KeyStore file on the filesystem
private static final String KEYSTORE_NAME = "iot_keystore";

);

How I can replay to WhatsApp notification from java code in android studio

Hello guys I'm using NotificationListenerService to get WhatsApp messages
But now I have a problem that I don't know how to replay to WhatsApp notifications
So here is the code and how I'm getting WhatsApp notifications but my problem is in how actually to replay on them
public class NotificationListener extends NotificationListenerService {
// StaticFields:
public static final String WHATSAPP_PACKAGE_NAME = "com.whatsapp";
// TAGS:
private static final String TAG = "NotificationListener";
private static final String NP_FIELD = "onNotificationPosted: ";
#Override
public void onNotificationPosted(StatusBarNotification sbn) {
super.onNotificationPosted(sbn);
// Fields:
ARPreferencesManager manager = new ARPreferencesManager(getApplicationContext());
String currentPackages = manager.getStringPreferences(ARPreferencesManager.PACKAGE_APP_NAME);
List<Chat.Messages> messages = new ArrayList<>();
// CheckingStatusBarNotification:
if (sbn.getPackageName().equals(WHATSAPP_PACKAGE_NAME)) {
// Initializing(DateTime):
String date = DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.SHORT).format(new Date());
List<Chat> chats;
// Initializing(Data):
String sender = sbn.getNotification().extras.getString(Notification.EXTRA_TITLE);
String msg = sbn.getNotification().extras.getString(Notification.EXTRA_TEXT);
String currentSenders = manager.getStringPreferences(ARPreferencesManager.SENDER_NAME);
// AddingData:
messages.add(new Chat.Messages(msg));
// Developing:
if (manager.getPreferences().contains(ARPreferencesManager.WHATSAPP_CHATS)) {
// Initializing:
chats = ARUtils.fromJsonToChats(manager.getStringPreferences(ARPreferencesManager.WHATSAPP_CHATS));
// Developing:
for (Chat chat : chats) {
if (chat.getSender().equals(sender)) {
// AddingTheNewMessage:
chat.getMessages().addAll(messages);
// AddingSender($Preferences):
if (!currentSenders.contains(sender)) {
// Initializing:
manager.setStringPreferences(ARPreferencesManager.SENDER_NAME, sender + ",");
// Refreshing:
currentSenders = manager.getStringPreferences(ARPreferencesManager.SENDER_NAME);
}
}
}
// CheckingSenders:
if (!currentSenders.contains(sender)) {
// Initializing:
Chat chat = new Chat(sender, "", date, null, messages);
// AddingTheNewChat:
chats.add(chat);
}
} else {
// Initializing:
chats = new ArrayList<>();
// Developing:
chats.add(new Chat(sender, "", date, null, messages));
}
// SettingPreferences:
manager.setStringPreferences(ARPreferencesManager.WHATSAPP_CHATS, ARUtils.fromChatsToJson(chats));
// Debugging:
ARUtils.debug(TAG, NP_FIELD, manager.getStringPreferences(ARPreferencesManager.WHATSAPP_CHATS));

Did you try using this function?
fun reply(action: Notification.Action, message: String, exception: Exception.() -> Unit = {}) {
try {
val sendIntent = Intent()
val msg = Bundle()
for (inputable in action.remoteInputs) {
msg.putCharSequence(inputable.resultKey, message)
}
RemoteInput.addResultsToIntent(action.remoteInputs, sendIntent, msg)
action.actionIntent.send(applicationContext, 0, sendIntent)
} catch (exception: Exception) {
exception(exception)
}
}
You can get Notification.Action for this way:
override fun onNotificationPosted(sbn: StatusBarNotification) {
super.onNotificationPosted(sbn)
val wExt = Notification.WearableExtender(sbn.notification)
for (action in wExt.actions) {
...

How to Retrieve Data from Node Server With Socket?

i've got problem getting data from Node server, i've searching many reference from internet, but i haven't found one yet that can solve my problem.
this is my node server
var socket = require('socket.io');
var express = require('express');
var app = express();
/*
var options = {
key: fs.readFileSync('cert/file.key'),
cert: fs.readFileSync('cert/file.crt')
};
var server = require('https').createServer(options, app);
*/
var server = require('http').createServer(app);
var io = socket.listen( server );
var port = process.env.PORT || 3000;
//server.listen(port, '103.126.57.4', function () {
server.listen(port, function () {
console.log('Server listening at port %d', port);
//console.log('Server listening at port %d', port, server.address());
});
io.on('connection', function (socket) {
console.log( "New client connected !" );
//console.log(socket.handshake.headers.host);
socket.on( 'new_message', function( data ) {
io.sockets.emit( 'new_message', {
idleveluser: data.idleveluser,
nama: data.nama,
level: data.level,
idchat: data.idchat,
pesan: data.pesan,
file: data.file,
reply: data.reply,
created_at: data.created_at
});
});
socket.on( 'new_chat_kelas', function( data ) {
io.sockets.emit( data.tabelchat, {
idleveluser: data.idleveluser,
nama: data.nama,
level: data.level,
idchat: data.idchat,
pesan: data.pesan,
file: data.file,
reply: data.reply,
created_at: data.created_at
});
});
socket.on( 'change_chat_status', function( data ) {
io.sockets.emit( 'change_status'+data.tabelchat, {
status: data.status
});
});
/*
socket.on('disconnect', function () {
console.log( "Client disconnected !" );
});
*/});
And this is my Android code
try {
//if you are using a phone device you should connect to same local network as your laptop and disable your pubic firewall as well
socket = IO.socket("http://192.168.100.13:3000");
socket.connect();
} catch (URISyntaxException e) {
e.printStackTrace();
}
refreshChat(url);
getTabelKelas();
getDiskusiChat(sharedDiskusi.getSpdiskusi());
private void getDiskusiChat(String tabelChat) {
socket.on(tabelChat, new Emitter.Listener() {
#Override
public void call(final Object... args) {
getActivity().runOnUiThread(new Runnable() {
#Override
public void run() {
JSONObject data = (JSONObject) args[0];
String jsonStr = data.toString();
Log.d("cek", "cek data : "+data);
Toast.makeText(mContext, (CharSequence) data, Toast.LENGTH_LONG).show();
try {

// //add the message to the messageList
//
// MessageList.add(m);
//
// // add the new updated list to the dapter
// chatBoxAdapter = new ChatBoxAdapter(MessageList);
//
// // notify the adapter to update the recycler view
//
// chatBoxAdapter.notifyDataSetChanged();
//
// //set the adapter for the recycler view
//
// myRecylerView.setAdapter(chatBoxAdapter);
} catch (JSONException e) {
e.printStackTrace();
}
}
});
}
});
}
i have try to Toast and log it but did not appear.
Can anyone help me to retrieve data ?I confuse how to get data if the data in the form of an array. I'm helped if someone helps me.
Sry for my bad english brother.
This is my log

Change this code line
String cek = String.valueOf(data.getJSONArray("idleveluser"));
to
String cek = String.valueOf(data.getString("idleveluser"));
as each item in the data object is a string.

How to pass two different JSON Objects to processFinish at two different times

I have this MainActivity which does two HTTP calls and return the JSON object back to the MainActivity class. I have seperately implemented the AsyncTask class and used the AsyncResponse interface to get the JSON object to the MainActivity by using the processFinish function call.
At first I came up with one HTTP call which worked perfectly.
Secondly I wanted to do another HTTP call in the same activity class. So I edit the code to cater the second HTTP call.
When I run the application, only the first HTTP call is working. When I call the second HTTP call it throws an exception saying reference to a null object
Then I checked by logging the onPostExecute method which calls the processFinish function. There I could see the JSON Object. So, that means the second JSON object doesn't get to the processFinish
How do I manage the second HTTP call? Please help me! I am new to Android.

Although I don't understand exactly what your problem is. There are few things I suggest you to do.
Here I go.
Don't use AsyncTask to make your http calls , use an intent services instead.
Use a OkHTTP library for your networking source
On your intent service send local broadcast with LocalBroadcastManager to broadcast your results from the http call.
Register broadcastsReceivers within your activities or fragments that will listen for those broadcasts that comes from the intent service
Why not to use AsyncTask: Because of configuration change - if you rotate your device you will lose that network calls-

Iphone emoji Unicode decode issue for push notification dispatch by APNs

My web service publish push notification to APNs and APNs send to destination IOS device.
When apns contain Unicode emoji on alert body push notification and Iphone os can't decode my Unicode emoji '\uD83D\uDE0A' app already kill.

Ios push notification managed by Ios OS
My Apache Catalina log
I am a web service cloud developer faceing this issue last one days for only Ios app. So please, if some body have knowledge or done before. please advise and refer me some idea.
Emoji in my push notifications link.
https://mixpanel.com/help/questions/articles/how-do-i-send-custom-parameters-like-emoji-in-my-push-notifications
Thanks

Finally, APNs issue resolve in (Ios app) on java web service code by this Unicode encode and decode process. (unescapeJava and escapeJava) from lib commons-lang-2.6.jar and class org.apache.commons.lang.StringEscapeUtils
emojiBytes = alertMsg.getBytes("UTF-8"); text = new String(emojiBytes, "UTF-8");
private static PushNotificationPayload createPayload(JSONObject jsonObject)
throws JSONException {
String alertMsg = Common.getStringUnicodeAsNull1(jsonObject,
AppConstants.FLD_ALERT_MSG);
byte[] emojiBytes=null;
String text=null;
try {
emojiBytes = alertMsg.getBytes("UTF-8");
text = new String(emojiBytes, "UTF-8");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//String emojiAsString = new String(emojiBytes, Charset.forName("UTF-8"));
//System.out.println("#####alertMsg: "+text);
Integer badgeCnt;
if (jsonObject.has(AppConstants.FLD_BADGE_CNT)){
badgeCnt = Common.getIntegerAsNull(jsonObject,
AppConstants.FLD_BADGE_CNT);
}else{
badgeCnt = AppConstants.VAL_ZERO;
}
PushNotificationPayload payload = createPayload(badgeCnt, text);
return payload;
}
String alertMsg = Common.getStringUnicodeAsNull1(jsonObject,
AppConstants.FLD_ALERT_MSG);
public static String getStringUnicodeAsNull1(JSONObject jsonObject,
String key) {
try {
if(jsonObject.isNull(key))
return null;
else
return StringEscapeUtils.unescapeJava(jsonObject.getString(key));
} catch (JSONException je) {
return null;
}
}
Respected sir and ma'am, If there is any other solution of java APNs emoji Unicode on IOS Push Notification.
Then please give me some hints.Thanks

you shouldn't need to mess about with html decoding. As you say the code point for smiling face is \u263A. In PHP you can represent that in a UTF8-encoded string as "\xE2\x98\xBA"
Lightning bolt (actually 'high voltage sign') is \u26A1 or "\xE2\x9A\xA1" in UTF-8.
Both these characters are present in some non-emoji fonts as regular Unicode symbols. You can see with:
<?php
header('Content-type: text/html; charset=utf-8');
echo "\xE2\x9A\xA1";
echo "\xE2\x98\xBA";
or other things...
for the googlers. json_encode() adds double \
$message = "\ue04a";
$body['aps'] = array(
'alert' => $message,
'sound' => 'default',
'type' => $type,
'param' => $param
);
$payload = json_encode($body);
$payload = str_replace("\", "\\", $payload);
Please check with this two way... i think this is helpfull for you.
