Image is not attached in quickblox for android

I have made a demo for sending image to private chat using QuickBlox, I am struggling to attach an image with the chat message, I have gone through its document and have used the below Links, with no luck
Attach an image
My code is as below:
chatMessage = new QBChatMessage();
sendButton = (Button) findViewById(R.id.chatSendButton);
sendButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final String messageText = messageEditText.getText().toString();
if (TextUtils.isEmpty(messageText)) {
return;
}
// Send chat message
//
// send a message
// ...
int fileId = R.raw.ic_launcher;
InputStream is = ChatActivity.this.getResources()
.openRawResource(fileId);
File file = FileHelper.getFileInputStream(is,
"sample_file.png", "myFile");
Boolean fileIsPublic = true;
QBContent.uploadFileTask(file, fileIsPublic, messageText,
new QBEntityCallbackImpl<QBFile>() {
#Override
public void onSuccess(QBFile qbFile, Bundle params) {
String publicUrl = qbFile.getPublicUrl();
System.out
.println("==========image uploaded success++++++++"
+ publicUrl);
id = qbFile.getId();
System.out
.println("===================image id+++++++++++"
+ id + "");
}
#Override
public void onError(List<String> errors) {
System.out
.println("==========image uploaded Errors++++++++"
+ errors.toString());
}
}, new QBProgressCallback() {
#Override
public void onProgressUpdate(int progress) {
}
});
QBAttachment atach = new QBAttachment("image");
atach.setId(id+"");
ArrayList<QBAttachment> aryatch = new ArrayList<QBAttachment>();
aryatch.add(atach);
chatMessage.setAttachments(aryatch);
chatMessage.setBody(messageText);
chatMessage.setProperty(PROPERTY_SAVE_TO_HISTORY, "1");
chatMessage.setDateSent(new Date().getTime() / 1000);
try {
chat.sendMessage(chatMessage);
} catch (XMPPException e) {
Log.e(TAG, "failed to send a message", e);
} catch (SmackException sme) {
Log.e(TAG, "failed to send a message", sme);
}
messageEditText.setText("");
if (dialog.getType() == QBDialogType.PRIVATE) {
showMessage(chatMessage);
}
}
});

Well it clear where the mistake is
your id is null here
atach.setId(id+"");
because it will != nil only in onSuccess block of uploadFileTask
So the right way is to forward all attachments logic inside onSuccess block of uploadFileTask
Because these QuickBlox request are asynchronous

AsyncTask. Problems with receiving from Java Server

I want to use AsyncTask for receiving ArrayList's(in this case) from Java server. To be sure, that I received something from server I'm trying to display it with Toast.
The Code is following:
public class MainActivity extends Activity {
private DataReceiving dRec;
private DataTransfer dTrans;
private EditText inputData;
private Button sendParametersBtn;
private Button startComputationBtn;
private TextView displayText;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
inputData=(EditText) findViewById(R.id.InputText);
sendParametersBtn=(Button) findViewById(R.id.button1);
startComputationBtn=(Button) findViewById(R.id.button2);
displayText=(TextView) findViewById(R.id.textView1);
sendParametersBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dRec = new DataReceiving();
dRec.execute();
}
});
private class DataReceiving extends AsyncTask<Void, Void, ArrayList>
{
#Override
protected ArrayList doInBackground(Void... params) {
ArrayList b = new ArrayList();
try {
b = receive();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return b;
}
protected void onPostExecute(ArrayList result) {
super.onPostExecute(result);
Toast toast=Toast.makeText(getApplicationContext(), result.toString(), Toast.LENGTH_SHORT);
toast.show();
}
public ArrayList receive () throws IOException, ClassNotFoundException
{
ServerSocket s= new ServerSocket(8888);
Socket incoming =s.accept();
ObjectInputStream ios = new ObjectInputStream(incoming.getInputStream());
ArrayList b = (ArrayList) ios.readObject();
ios.close();
incoming.close();
s.close();
return b;
}
While clicking the sendParametersBtn nothing happening.
P.S. I can successfully transmit from Android to Server. So its not a connection or permission problem.
Thank you for help

Hi If your getting some thing from server you have to call web server url for fetching data. After data arrives response have some type it will JSON/XML if they are restful services if they are SOAP services they are in envelope. So after response return get that and parse them as per logic.
Look for HTTP get/post (for ping to server and get data )and parsing (JSON/XML).

Figured out! I removed receive method into doInBackground.

Issue about using Async with an Android Client

I am currently creating a project that needs to have a simple async task to take care of a thread running behind the scenes. The user needs to login. I am using another class called PVAndroid Client that supplies useful methods and has an XML serializer form packets for me. I am completely new to working with threads or doing anything with servers, so this may be completely wrong or somewhat right.
I get the data the user entered: the ip address and port, their username (I split this into first and last name), their region they selected. I encrypt their password, and attempt to connect to the tcp using ip address and port number. I am trying to work in the async task but am kind of confused on what I should do. Can anyone guide me in the right direction and help me out?
Thank you I really appreciate it.

Never do this again. There is no need to create new Thread in doInBackground method which actually running on background Thread. So remove it.
The advice to you is tricky because you need to read about Threads, work with Connection etc. So the best advice to you is to read some tutorials, examples of basic applications and read references. So you can start here:
Android TCP Client and Server Communication Programming–Illustrated with Example

I cannot see, where you are yoursing your Task, but I see that you are doing something weired inside doInBackground()! There is absolutely NO reason, to create your own Thread inside it.
remove that, and you could just use your Task like this:
UploadTask task = new UploadTask();
task.execute("someString", "anotherString", "addAsManyStringsYouNeed");
The docs from AsyncTask are very helpfull, too.

error: Only the original thread that created a view hierarchy can touch its views

Hi and thank you for looking at my question.
I am an intermediate programmer in C but an Android newbie. I have been trying to get a chat programming working. Assuming everything else in the code below works perfectly. The one question I like to ask is when I try to setText() from a thread running, I get an exception above. I looked at many many websites and here too. Found many things, but I really do not understand. Please explain to me in the most simple way or offer me some simple fix if possible.
Thank you very much!!

In your run() method:
Message msg = new Message();
String textTochange = "text";
msg.obj = textTochange;
mHandler.sendMessage(msg);
Create the mHandler in your UI thread;
Handler mHandler = new Handler() {
#Override
public void handleMessage(Message msg) {
String text = (String)msg.obj;
//call setText here
}
};

You are not on the UI thread when setting the text. You need to be on UI if you want to work on UI items. Create a message handler on the UI thread, post your messages to it and call setText from the handler on the UI thread.

you can do this whenever you are in a thread:
msgToServer.post(new Runnable() {
public void run() {
msgToServer.setText("your text here");
}
}

Your problem is that there are certain interactions that you can only do on the UI thread. This is one of them.
Looks like you might want to use AsyncTask
http://developer.android.com/reference/android/os/AsyncTask.html
Basically you could make your Runnable an AsyncTask instead and do the setText in onProgressUpdate, which gets run on the UIThread.

If you would like to use an AsyncTask to run in the background this is how I would do it:
public class UpdateTextProgress_Task extends AsyncTask<Void,String,Void> {
Socket socket;
EditText chatFromServer;
UpdateTextProgress_Task(EditText chatFromServer, Socket socket){
this.socket = socket;
this.chatFromServer = chatFromServer;
}
#Override
protected Void doInBackground(Void... params) {
try {
BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
String str = "FIRSTMESSAGEFROMSERVER";
while(true){
if (str.equals("FIRSTMESSAGEFROMSERVER")){
str = in.readLine();
}
else{
