Not able to upload the audio file along with the data to the server through nougat version of android

I'm not able to upload the audio file to the server through the nougat version of android, The audio is recorded through the media recorder and saved on the device.Here is the code, the same is working for all the versions of android except nogat ,though in nogat the media is recorded and saved in device , but it not being uploaded on the server.
private void submitRecording() {
CallLogsModel.idle++;
final String filename = "file.MP3";
final String path = Environment.getExternalStorageDirectory() + "/" + filename;
JSONObject jObject = new JSONObject();
String json = "";
try {
String uniquecode = PreferenceConfigration.getPreference(Constants.PreferenceConstants.UNIQUE_CODE);
String token= UtilityMethods.tokenValue();
Log.e("Token",token);
jObject.put("uniquecode",uniquecode);

jObject.put("token", token);
Log.e("formed",jObject.toString());
if (path.equals("") || path.equals(null) || path.equals("null")) {
jObject.put("aboutphoto", "nophoto");
}
else

how to repeate sending value by socket

I have this client and server communication program. I got the idea from Android-er website.
This codes send a one random number when the customer pressing the connection button and I want to send new random number of every five minutes when the client had been connected with server.
Client code:
public class MainActivity extends AppCompatActivity {
TextView textResponse;
EditText editTextAddress, editTextPort;
Button buttonConnect, buttonClear;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editTextAddress = (EditText)findViewById(R.id.address);
editTextPort = (EditText)findViewById(R.id.port);
buttonConnect = (Button)findViewById(R.id.connect);
buttonClear = (Button)findViewById(R.id.clear);
textResponse = (TextView)findViewById(R.id.response);
buttonConnect.setOnClickListener(buttonConnectOnClickListener);
buttonClear.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
textResponse.setText("");
}});
}
View.OnClickListener buttonConnectOnClickListener = new View.OnClickListener(){
#Override
public void onClick(View arg0) {
MyClientTask myClientTask = new MyClientTask(
editTextAddress.getText().toString(),
Integer.parseInt(editTextPort.getText().toString()));
myClientTask.execute();
}};
public class MyClientTask extends AsyncTask<Void, Void, Void> {
String dstAddress;
int dstPort;
String response = "";
MyClientTask(String addr, int port){
dstAddress = addr;
dstPort = port;
}
#Override
protected Void doInBackground(Void... arg0) {
Socket socket = null;
try {
socket = new Socket(dstAddress, dstPort);
ByteArrayOutputStream byteArrayOutputStream =
new ByteArrayOutputStream(1024);
byte[] buffer = new byte[1024];
int bytesRead;
InputStream inputStream = socket.getInputStream();
/*
* notice:
* inputStream.read() will block if no data return
*/
while ((bytesRead = inputStream.read(buffer)) != -1){
byteArrayOutputStream.write(buffer, 0, bytesRead);
response += byteArrayOutputStream.toString("UTF-8");
}
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
response = "UnknownHostException: " + e.toString();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
response = "IOException: " + e.toString();
}finally{
if(socket != null){
try {
socket.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
return null;
}
#Override
protected void onPostExecute(Void result) {
textResponse.setText(response);
super.onPostExecute(result);
}
}
}
and this is the code of server:
public class MainActivity extends AppCompatActivity {
TextView info, infoip, msg, randGen;
String message = "";
ServerSocket serverSocket;
String vRand="";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

infoip = (TextView) findViewById(R.id.infoip);
msg = (TextView) findViewById(R.id.msg);
randGen= (TextView)findViewById(R.id.viewRand);
infoip.setText(getIpAddress());
Thread socketServerThread = new Thread(new SocketServerThread());
socketServerThread.start();
}
public String rGenerate() {
Random rand= new Random();
int number= rand.nextInt(500-251)+251;
vRand = String.valueOf(number);
//randGen.setText(vRand);
return vRand;
}
#Override
protected void onDestroy() {
super.onDestroy();
if (serverSocket != null) {
try {
serverSocket.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
private class SocketServerThread extends Thread {
static final int SocketServerPORT = 8080;
int count = 0;
#Override
public void run() {
try {
serverSocket = new ServerSocket(SocketServerPORT);
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
info.setText("I'm waiting here: "
+ serverSocket.getLocalPort());
}
});
while (true) {
Socket socket = serverSocket.accept();
count++;
message += "#" + count + " from " + socket.getInetAddress()
+ ":" + socket.getPort() + "\n";
MainActivity.this.runOnUiThread(new Runnable() {
#Override
public void run() {
msg.setText(message);
}
});
SocketServerReplyThread socketServerReplyThread = new SocketServerReplyThread(
socket, count);
socketServerReplyThread.run();
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
private class SocketServerReplyThread extends Thread {
private Socket hostThreadSocket;
int cnt;
SocketServerReplyThread(Socket socket, int c) {
hostThreadSocket = socket;
cnt = c;
}
#Override
public void run() {
OutputStream outputStream;
String num =rGenerate();
try {
outputStream = hostThreadSocket.getOutputStream();
PrintStream printStream = new PrintStream(outputStream);
printStream.print(num);
printStream.close();
message += num + "\n";

}
}
private String getIpAddress() {
String ip = "";
try {

while (enumNetworkInterfaces.hasMoreElements()) {

You can use handler to perform tasks at specific delay. I assumed you know how to send the random numbers using sockets so i wont mess socket codes
Button button = (Button) findViewById(R.id.start_button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
handler.postDelayed(new Runnable() {
#Override
public void run() {
sendData();
handler.postDelayed(this, 15000);
}
}, 15000);
}
});
private void sendData(){
new Worker().execute();
}
private class Worker extends AsyncTask<Void, Void, String>{
private static final String TAG = "Worker";
#Override
protected String doInBackground(Void... params) {
return "Hello There";
}
#Override
protected void onPostExecute(String s) {
Log.i(TAG, s);
}
}

You can use a Handler to do something in a certain time period. Try this
Handler customHandler = new android.os.Handler();
static final int SOCKET_VERIFY_TIME = 5000; //milliseconds
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
...
customHandler.postDelayed(updateTimerThread, SOCKET_VERIFY_TIME);
...
}
private Runnable updateTimerThread = new Runnable() {
public void run()
{
if(socket != null) {
if(socket.connected()) {
socket.emit("eventNumber", randNumber);
}
}
customHandler.postDelayed(this, SOCKET_VERIFY_TIME);
}
};
if you want stop updates use this
customHandler.removeCallbacks(updateTimerThread);
In your Client
public class MainActivity extends AppCompatActivity {
TextView textResponse;
EditText editTextAddress, editTextPort;
Button buttonConnect, buttonClear;
Handler customHandler = new android.os.Handler();
static final int SOCKET_VERIFY_TIME = 5000; //milliseconds
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editTextAddress = (EditText)findViewById(R.id.address);
editTextPort = (EditText)findViewById(R.id.port);
buttonConnect = (Button)findViewById(R.id.connect);
buttonClear = (Button)findViewById(R.id.clear);
textResponse = (TextView)findViewById(R.id.response);
buttonConnect.setOnClickListener(buttonConnectOnClickListener);
buttonClear.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
textResponse.setText("");
}});
/***** Events Socket ***********/
socket = IO.socket(new URI(URL_SERVER));
socket.on(Socket.EVENT_CONNECT, new Emitter.Listener() {
#Override
public void call(Object... args) {
yourActivity.this.runOnUiThread(new Runnable() {

});
}
})
}

public void run()
{
if(socket != null) {

socket.emit("eventNumber", randNumber);
}
}
customHandler.postDelayed(this, SOCKET_VERIFY_TIME);
}
};
public class MyClientTask extends AsyncTask<Void, Void, Void> {

Android send received data from a socket service to Activity

I am looking for a way to send received data (receive while flag is set) from a socket service to an activity that is bound to the service. What is the best way to do this ? Handlers , AsyncTask or something else ?
this is the SocketClass I am using to start a connection and handle the incoming messages :
class connectSocket implements Runnable {
#Override
public void run() {
running= true;
try {
socket = new Socket(serverAddr, SERVERPORT);
try {
mBufferOut = new ObjectOutputStream(socket.getOutputStream());
mBufferIn = new ObjectInputStream(socket.getInputStream());
while(running){
msg = (Message) mBufferIn.readObject();
}
}
catch (Exception e) {
Log.e("TCP", "S: Error", e);
}
} catch (Exception e) {
Log.e("TCP", "C: Error", e);
}
}
}
Update :
public class SocketService extends Service {
private static final String TAG = "com.oos.kiesa.chat";
public static final String SERVERIP = "192.168.X.X";
public static final int SERVERPORT = 4444;
private ObjectOutputStream mBufferOut;
private ObjectInputStream mBufferIn;
Socket socket;
InetAddress serverAddr;
boolean mRun;
Object msg;
public Integer command;
#Override
public IBinder onBind(Intent intent) {
return myBinder;
}
private final IBinder myBinder = new LocalBinder();
public class LocalBinder extends Binder {
public SocketService getService() {
return SocketService.this;
}
}
#Override
public void onCreate() {
super.onCreate();
}
public void IsBoundable(){
Toast.makeText(this,"is boundable", Toast.LENGTH_LONG).show();
}
public void sendMessage(String message) throws IOException {
if (mBufferOut != null) {
mBufferOut.writeObject(message);
mBufferOut.flush();
}
}
public void sendMessage(Message message) throws IOException {
if (mBufferOut != null) {
mBufferOut.writeObject(message);
mBufferOut.flush();
}
}
public void sendMessage(User user) throws IOException {
if (mBufferOut != null) {
mBufferOut.writeObject(user);
mBufferOut.flush();
}
}
public void sendMessage(int command) throws IOException {
if (mBufferOut != null) {
mBufferOut.writeInt(command);
mBufferOut.flush();
}
}
#Override
public int onStartCommand(Intent intent,int flags, int startId){
super.onStartCommand(intent, flags, startId);
System.out.println("I am in on start");
Runnable connect = new connectSocket();
new Thread(connect).start();
return START_STICKY;
}
public void stopClient() throws IOException{
if (mBufferOut != null) {
mBufferOut.flush();
mBufferOut.close();
}
mBufferIn = null;
mBufferOut = null;
socket.close();
}
class connectSocket implements Runnable {
#Override
public void run() {
mRun = true;
try {
socket = new Socket(serverAddr, SERVERPORT);
try {
mBufferOut = new ObjectOutputStream(socket.getOutputStream());
mBufferIn = new ObjectInputStream(socket.getInputStream());
while(mRun){
switch(command.intValue()){
case Constants.ADD_MESSAGE:
msg = (Message) mBufferIn.readObject(); // send message to Activity
break;
}
}
}
catch (Exception e) {
Log.e("TCP", "S: Error", e);
}
} catch (Exception e) {
Log.e("TCP", "C: Error", e);
}
}
}
#Override
public void onDestroy() {
super.onDestroy();
try {
socket.close();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
socket = null;
}
}
Some guidance / examples would be greatly appreciated

I am sending you mine, hope it will help :

}
public static SocketRequestHandler pingAll(Activity activity, TCPResponseModel tcpResponseDS, SaloonListener listener) {

requestHandler.start();
return requestHandler;

byte[] bytes;
String pingStr = "";
clientSocketInputStream = new DataInputStream(clientSocekt.getInputStream());
while (true) {
bytes = new byte[1024];
clientSocketInputStream.read(bytes);
bytes = trim(bytes);
if (bytes.length > 0 && !doSkip) {
String newString = new String(bytes, "UTF-8");
String decoded = pingStr + newString;
pingStr = checkForMessage(decoded);
responseStringComplete += newString;
}
if (doSkip) {
break;
}
}

} catch (UnknownHostException e) {

}
}
To broadcast chat data just do :
msg = (Message) mBufferIn.readObject(); // Do code after this line
Intent localIntent = new Intent("CHAT_MESSAGE");
localIntent.putExtra("message", msg);
LocalBroadcastManager.getInstance(context).sendBroadcast(localIntent);
Now in the activity where you are showing the chat list you can do
class ReceiveMessages extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
final String action = intent.getAction();
if (action.equals("CHAT_MESSAGE")) {
runOnUiThread(new Runnable() {
#Override
public void run() {
String chatMessage = getIntent().getStringExtra("message");
//get data from intent and update your chat list.
}
});
}
}
}
ReceiveMessages myReceiver;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//your code
myReceiver = new ReceiveMessages();
}
#Override
protected void onStart() {
super.onStart();
LocalBroadcastManager.getInstance(this).registerReceiver(myReceiver,
new IntentFilter("CHAT_MESSAGE"));
}
#Override
protected void onStop() {
super.onStop();
LocalBroadcastManager.getInstance(this).unregisterReceiver(myReceiver);
}

SignalR for Android: how can I pass dynamic class to SubscriptionHandler1

I have a method startSignalR calling
mHub.on("broadcastMessage",
new SubscriptionHandler1<CustomMessage>() {
#Override
public void run(final CustomMessage msg) {
final String finalMsg = msg.UserName + ": " + msg.Message;

Now I wanna a dynamic class (not only CustomMessage) passed to the method, I have used Class <T> tClass as parameter of "startSignalR", but get error at
new SubscriptionHandler1<tClass>()
Would you please tell me how to solve this?

I have found a solution

Platform.loadPlatformComponent(new AndroidPlatformComponent());
Credentials credentials = new Credentials() {
#Override
public void prepareRequest(Request request) {

}
};
mConnection = new HubConnection(serverUrl);
mConnection.setCredentials(credentials);
mHub = mConnection.createHubProxy(SERVER_HUB_CHAT);
if (transport.equals("ServerSentEvents")) {
mTransport = new ServerSentEventsTransport(mConnection.getLogger());
} else if (transport.equals("LongPolling")) {
mTransport = new LongPollingTransport(mConnection.getLogger());
}
mAwaitConnection = mConnection.start(mTransport);
try {
mAwaitConnection.get();
} catch (InterruptedException e) {

How to view the Intents a BroadcastReceiver is receiving?

I have an infinite loop somewhere in my code, indicative of my group messaging BroadcastReceiver continually accepting only the first message in the database, over and over again, until I stop running the application. Note that the repeating of the message only occurs in the client app and not in the server database.
Is there way to trace what intent the BroadcastReceiver is receiving? ie. be able to view the intents the BroadcastReceiver is acting on to locate the source of these actions?
My code for both sending and receiving a group message if it helps: (BroadcastReceiver is near the bottom)
