How to get correct entity content length to show progress in progress dialog?

I want to upload multiple image files using Android MultiPart Entity via AsyncTask in an activity. When I attempt to upload single image file then the progress dialog shows correct progress and as soon as 100% progress is reached the dialog dismisses and does the further tasks. But, when I am attempting to upload multiple image files it shows the 100% progress and the progress dialog is stuck till other image files are being uploaded to server. I add the multiple image files to entity using a for loop. But when I try to get the content length it seems that I am getting wrong value.

How to send large video file to server in android

Hi i am trying to upload large video files to server using Volley library but when i request big video files to server it's taking too large time and video not uploading there is server side limitation 4MB
how can i resolve this problem please help me some one
my code:
RequestQueue queue = Volley.newRequestQueue(context.getApplicationContext());
final String url = Constants.SERVER_URL + serverUrl;

As per android docs here
An asynchronous task is defined by a computation that runs on a
background thread and whose result is published on the UI thread.
And loading data from URL with Handler is not a good thing. Instead use Executor or ThreadPoolExecutor to do heavy background tasks.

You Can Use
getActivity().runOnUiThread(new Runnable() {
#Override
public void run() {
getResponse();
}
});

you can do like this:
class MyAsyncTask extends AsyncTask<Object,Object,Object>{
Private Context c;
private Handler handler;
private final static int YOUR_WORK_ID = 0x11;
public MyAsyncTask(Context c,Handler handler){
this.c = c;
this.handler = handler;
}
protected Object doInBackground(Object... params){
//do your work
...
Message m = handler.obtainMessage();
m.what = YOUR_WORK_ID;
...
handler.sendMessage().sendToTarget();
}
}
And in your fragment ,you can init a handler as params to MyAsyncTask,and deal with you work in handleMessage();

Multiple progress bar on image

I am calling above code in my main activity and i am using this to upload images and video.
please help me how i can set progress bar on multiple images same as in whatsapp
Thanks

You could pass the View to the AsyncTask, by create new constructor then show/hide it, notice that you have to runOnUIThread for the view.
private class UploadFileToServer extends AsyncTask<Void, Integer, String> {
ImageView iv_loading;
public UploadFileToServer(ImageView iv_loading){
this.iv_loading = iv_loading;
}
#Override
protected void onPreExecute() {
super.onPreExecute();
runOnUiThread(new Runnable() {
#Override
public void run() {
iv_loading.setVisibility(View.VISIBLE);
}
}
);
}
...
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
runOnUiThread(new Runnable() {
#Override
public void run() {
iv_loading.setVisibility(View.GONE);
}
}
);
}
}

ProcessDialog is not appearing properly?

This is my function that is in LoginActivity.java.So onclick of button i am calling this function.
public void postHttpRequest(String userId,String pass,TextView error){
RequestClient reqClient = new RequestClient(LoginActivity.this);
String AppResponse = null;
try {
url = "myurl";
Log.d("URL", url);
AppResponse = reqClient.execute().get();
String status = ValidateLoginStatus.checkLoginStatus(AppResponse);
Log.d("Status recived", status);
if(status.equals("200")){
saveInformation(userId,pass);
startingActivity(HOST_URL);
}else{
error.setText("Incorrect UserName or Password");
}
} catch (Exception e) {
Log.e("Exception Occured", "Exception is "+e.getMessage());
}
}
From this function i am calling a AsynkTask for Http Communication.So onclick of button when i am geeting the response then my processDialog in opening just for one sec.I want as i click the buttoon my processDialog should get open utill i got the response
public class RequestClient extends AsyncTask<String, Void, String>{
ProgressDialog pDialog;
Context context;
public RequestClient(Context c) {
context = c;
}
#Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(context);
pDialog.setMessage("Authenticating user...");
pDialog.show();
}
#Override
protected String doInBackground(String... aurl){
String responseString="";
DefaultHttpClient httpClient=new DefaultHttpClient();
try {
HttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet(LoginActivity.url);
HttpResponse responseGet = client.execute(get);
HttpEntity resEntityGet = responseGet.getEntity();
if (resEntityGet != null) {
responseString = EntityUtils.toString(resEntityGet);
Log.i("GET RESPONSE", responseString);
}
} catch (Exception e) {
Log.d("ANDRO_ASYNC_ERROR", "Error is "+e.toString());
}
Log.d("ANDRO_ASYNC_ERROR", responseString);
httpClient.getConnectionManager().shutdown();
return responseString;
}
#Override
protected void onPostExecute(String response) {
super.onPostExecute(response);
if(pDialog!=null)
pDialog.dismiss();
}
}
So please suggest me what changes i have to make so that processDialog should display properly in the center of the device

//add style in your progressbialog
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(context);
pDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
pDialog.setMessage("Authenticating user...");
if (pDialog != null && !pDialog.isShowing()) {
pDialog.show();
}
}

AsyncTask return value only after using get() method
Drawing from the above link
Calling the get() method of AsyncTask will block the main thread and wait for the result to be returned. This effectively makes using an AsyncTask become a synchronous operation in which case there's no point in using an AsyncTask.
The only reason I can think of to use the get() method would be from a thread other than the main (UI) thread although I can't think of many reasons to do that.
On Button click
RequestClient reqClient = new RequestClient(LoginActivity.this,new TheInterface() {
#Override
public void theMethod(String result) {
Log.i("Result =",result);
}
});
reqClient.execute(url); // no get(). pass url to doInBackground()
In your activity class
public interface TheInterface {
public void theMethod(String result);
}
}
AsyncTask
public class RequestClient extends AsyncTask<String, Void, String>{
ProgressDialog pDialog;
Context context;
TheInterface listener;
public RequestClient(Context c,TheInterface listen) {
context = c;
listener = listen;
}
#Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(context);
pDialog.setMessage("Authenticating user...");
pDialog.show();
}
#Override
protected String doInBackground(String... aurl){
String responseString="";
HttpClient client;
try {
HttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet(aurl[0]); // url
HttpResponse responseGet = client.execute(get);
HttpEntity resEntityGet = responseGet.getEntity();
if (resEntityGet != null) {
responseString = EntityUtils.toString(resEntityGet);
Log.i("GET RESPONSE", responseString);
}
} catch (Exception e) {
Log.d("ANDRO_ASYNC_ERROR", "Error is "+e.toString());
}
Log.d("ANDRO_ASYNC_ERROR", responseString);
client.getConnectionManager().shutdown();
return responseString;
}
#Override
protected void onPostExecute(String response) {
super.onPostExecute(response);
pDialog.dismiss();
if (listener != null)
{
listener.theMethod(result);
}
}
}

It seems that your button code is not correct, because it's async, but you are trying to use it as standart sync code.
Try to move this code into onPostExecute:
String status = ValidateLoginStatus.checkLoginStatus(response);
Log.d("Status recived", status);
if(status.equals("200")){
saveInformation(userId,pass);
startingActivity(HOST_URL);
}else{
error.setText("Incorrect UserName or Password");
}
and make this button click code:
public void postHttpRequest(String userId,String pass,TextView error){
RequestClient reqClient = new RequestClient(LoginActivity.this);
String AppResponse = null;
try {
url = "myurl";
Log.d("URL", url);
reqClient.execute();
} catch (Exception e) {
Log.e("Exception Occured", "Exception is "+e.getMessage());
}
}
