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;
MultipartAPI multipartAPI = new MultipartAPI(url, params, authenticationHeaders,fileType,fileMap, reqType,
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyErrorvolleyError) {
// progressDialog.dismiss();
if (volleyError != null) {
}
}
}, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
System.out.println("------->" + response);
}
});
int socketTimeout = 450000;
RetryPolicy policy = new DefaultRetryPolicy(socketTimeout,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
multipartAPI.setRetryPolicy(policy);
queue.add(multipartAPI);

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.

Move the code that is in a thread in onPostExecute() to doInBackground() because this is running in other thread and them refresh you UI in onPostExecute()
A mock example:
#Override
protected String doInBackground(String... params) {
//RUN ALL THAT YOU WANT IN A DIFFERENT THREAD
}
#Override
protected void onPostExecute(final String response) {
//REFRESH THE UI
}
If you are using AsynkTask, you can have a try on onPreExecute and onPostExecute methods that both runs on the UI thread.
Or you can use a handler to update UI.
In your UI thread create an object of Handler like this
private Handler handler = new Handler() {
#Override
public void handleMessage(Message msg) {
//Update UI here
//use msg.obj if you have sent Object from background thread
//use msg.what if you have sent Integer from background thread
//Update UI if you have just trigger the handler using sendEmptyMessage(your UI/View gets data from Global Variable)
}
};
Two ways we can trigger Hanler which is created in UI thread
1)handler.sendMessage(Message);
2)handler.sendEmptyMessage(0);
Inside on postExecute of your AsyncTask write below Code based on your requirement
//Message msg=Message.obtain();
//msg.obj=YourObject;//If you want to pass Object
//msg.what=Integer;//If you want to pass Integer
//handler.sendMessage(msg);//to send Message objectdefined above
handler.sendEmptyMessage(0);//If you simply want to trigger

AsyncTasks are tricky to cancel. Better you use OKHTTP for example, so you cancel it this way
to cancel asynctask uyou can call uploadtoserver.cancel(true);
I have multiple images and i am uploading on php server using asynctask my problem is i want to show circular progress bar on every image individually like whatsapp but don't know how to do. here is my code

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);
}
}
);
}
}
I am uploading an image on server by using async task and in the end I want to return value of uploaded file url. How can I do that
I am calling asynctask as
new Config.UploadFileToServer(loginUserInfoId, uploadedFileURL).execute();
and my asynctask function is as:
public static final class UploadFileToServer extends AsyncTask<Void, Integer, String> {
String loginUserInfoId = "";
String filePath = "";
long totalSize = 0;
public UploadFileToServer(String userInfoId, String url){
loginUserInfoId = userInfoId;
filePath = url;
}
#Override
protected void onPreExecute() {
// setting progress bar to zero
super.onPreExecute();
}
#Override
protected void onProgressUpdate(Integer... progress) {
// Making progress bar visible
// updating progress bar value
}
#Override
protected String doInBackground(Void... params) {
return uploadFile();
}
#SuppressWarnings("deprecation")
private String uploadFile() {
String responseString = null;
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(Config.HOST_NAME + "/AndroidApp/AddMessageFile/"+loginUserInfoId);
try {
AndroidMultiPartEntity entity = new AndroidMultiPartEntity(
new AndroidMultiPartEntity.ProgressListener() {
#Override
public void transferred(long num) {
publishProgress((int) ((num / (float) totalSize) * 100));
}
});
File sourceFile = new File(filePath);
// Adding file data to http body
entity.addPart("file", new FileBody(sourceFile));
totalSize = entity.getContentLength();
httppost.setEntity(entity);
// Making server call
HttpResponse response = httpclient.execute(httppost);
HttpEntity r_entity = response.getEntity();
int statusCode = response.getStatusLine().getStatusCode();
if (statusCode == 200) {
// Server response
responseString = EntityUtils.toString(r_entity);
} else {
responseString = "Error occurred! Http Status Code: "
+ statusCode;
}
} catch (ClientProtocolException e) {
responseString = e.toString();
} catch (IOException e) {
responseString = e.toString();
}
responseString = responseString.replace("\"","");
return responseString;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
}
}
Try my code as given below.
public Result CallServer(String params)
{
try
{
MainAynscTask task = new MainAynscTask();
task.execute(params);
Result aResultM = task.get(); //Add this
}
catch(Exception ex)
{
ex.printStackTrace();
}
return aResultM;//Need to get back the result
}
You've almost got it, you should do only one step. As I can see, you are returning the result at the doInBackground method (as a result of calling uploadFile). Now, this value is passed to the onPostExecute method, which is executed on the main thread. In its body you should notify components, which are waiting for result, that result is arrived. There are a lot of methods to do it, but if you don't want to used 3rd party libs, the simplest one should be to inject listener at the AsyncTask constructor and call it at the onPostExecute. For example, you can declare the following interface:
public interface MyListener {
void onDataArrived(String data);
}
And inject an instance implementing it at the AsyncTask constructor:
public UploadFileToServer(String userInfoId, String url, MyListener listener){
loginUserInfoId = userInfoId;
filePath = url;
mListener = listener;
}
Now, you can simply use it at the onPostExecute:
#Override
protected void onPostExecute(String result) {
listener.onDataArrived(result);
super.onPostExecute(result); //actually `onPostExecute` in base class does nothing, so this line can be removed safely
}
If you are looking for a more complex solutions, you can start from reading this article.
