Implement ProgressDialog in a multi-user boot order

I use the following method to upload an image from Android to the server.

public void uploadMultipart() { //getting name for the image String name = editText.getText().toString().trim(); //getting the actual path of the image String path = getPath(filePath); progress = ProgressDialog.show(this, "Subiendo imagen", "Por favor, espere...", true); //Uploading code try { String uploadId = UUID.randomUUID().toString(); //Creating a multi part request new MultipartUploadRequest(this, uploadId, Constants.UPLOAD_URL) .addFileToUpload(path, "image") //Adding file .addParameter("name", name) //Adding text parameter to the request .setNotificationConfig(new UploadNotificationConfig()) .setMaxRetries(2) .startUpload(); //Starting the upload } catch (Exception exc) { Toast.makeText(this, exc.getMessage(), Toast.LENGTH_SHORT).show(); } }

Now I want to implement a ProgressDialog, which should be fired when the download is finished. I do not know when the request for several parts ends.

thanks

The presence of this class:

 public class SingleUploadBroadcastReceiver extends UploadServiceBroadcastReceiver { public interface Delegate { void onProgress(int progress); void onProgress(long uploadedBytes, long totalBytes); void onError(Exception exception); void onCompleted(int serverResponseCode, byte[] serverResponseBody); void onCancelled(); } private String mUploadID; private Delegate mDelegate; public void setUploadID(String uploadID) { mUploadID = uploadID; } public void setDelegate(Delegate delegate) { mDelegate = delegate; } @Override public void onProgress(String uploadId, int progress) { if (uploadId.equals(mUploadID) && mDelegate != null) { mDelegate.onProgress(progress); } } @Override public void onProgress(String uploadId, long uploadedBytes, long totalBytes) { if (uploadId.equals(mUploadID) && mDelegate != null) { mDelegate.onProgress(uploadedBytes, totalBytes); } } @Override public void onError(String uploadId, Exception exception) { if (uploadId.equals(mUploadID) && mDelegate != null) { mDelegate.onError(exception); } } @Override public void onCompleted(String uploadId, int serverResponseCode, byte[] serverResponseBody) { if (uploadId.equals(mUploadID) && mDelegate != null) { mDelegate.onCompleted(serverResponseCode, serverResponseBody); } } @Override public void onCancelled(String uploadId) { if (uploadId.equals(mUploadID) && mDelegate != null) { mDelegate.onCancelled(); } } }

Then in your activity:

 public class YourActivity extends Activity implements SingleUploadBroadcastReceiver.Delegate { private static final String TAG = "AndroidUploadService"; private final SingleUploadBroadcastReceiver uploadReceiver = new SingleUploadBroadcastReceiver(); @Override protected void onResume() { super.onResume(); uploadReceiver.register(this); } @Override protected void onPause() { super.onPause(); uploadReceiver.unregister(this); } public void uploadMultipart(final Context context) { try { String uploadId = UUID.randomUUID().toString(); uploadReceiver.setDelegate(this); uploadReceiver.setUploadID(uploadId); new MultipartUploadRequest(context, uploadId, "http://upload.server.com/path") .addFileToUpload("/absolute/path/to/your/file", "your-param-name") .setNotificationConfig(new UploadNotificationConfig()) .setMaxRetries(2) .startUpload(); } catch (Exception exc) { Log.e(TAG, exc.getMessage(), exc); } } @Override public void onProgress(int progress) { //your implementation } @Override public void onProgress(long uploadedBytes, long totalBytes) { //your implementation } @Override public void onError(Exception exception) { //your implementation } @Override public void onCompleted(int serverResponseCode, byte[] serverResponseBody) { //your implementation } @Override public void onCancelled() { //your implementation } }

You will now have the appropriate callbacks on successful / unsuccessful downloads.

Here is an example method. Start the execution dialog by clicking and close it on onCompleted

 public void uploadMultipart() { try { String path = getPath(filePath); final File file = new File(path); final String namFile = file.getName(); final String ext = getMimeType(path); Toast.makeText(this, "Uploading file. Please wait...", Toast.LENGTH_SHORT).show(); final String uploadId = UUID.randomUUID().toString(); //Creating a multi part request String boundary = "---------------------------14737809831466499882746641449"; new MultipartUploadRequest(this, uploadId, UPLOAD_URL) .addHeader("Content-Type", "multipart/form-data; boundary="+boundary) .addFileToUpload(path, "image") //Adding file .setNotificationConfig(new UploadNotificationConfig()) .setMaxRetries(2) .setDelegate(new UploadStatusDelegate() { @Override public void onProgress(Context context, UploadInfo uploadInfo) { // your code here Log.d("On Progress", String.valueOf(uploadInfo)); } @Override public void onError(Context context, UploadInfo uploadInfo, Exception exception) { // your code here Log.d("On error", String.valueOf(exception)); } @Override public void onCompleted(Context context, UploadInfo uploadInfo, ServerResponse serverResponse) { // YourClass obj = new Gson().fromJson(serverResponse.getBodyAsString(), YourClass.class); Log.d("serverResponse", String.valueOf(serverResponse)); } @Override public void onCancelled(Context context, UploadInfo uploadInfo) { // your code here Log.d("On cancled", String.valueOf(uploadInfo)); } }) .startUpload(); } catch (Exception exc) { // Toast.makeText(this, exc.getMessage(), Toast.LENGTH_SHORT).show(); Toast.makeText(this, "Error While uploading...", Toast.LENGTH_SHORT).show(); } }

 public void upload_file_multipart() { String url = " http://server.printme.uz/v1/order/make-order"; try { String uploadId = UUID.randomUUID().toString(); uploadReceiver.setDelegate((SingleUploadBroadcastReceiver.Delegate) this); uploadReceiver.setUploadID(uploadId); //Creating a multi part request MultipartUploadRequest request = new MultipartUploadRequest(this, uploadId, UPLOAD_URL); request.addFileToUpload(images.getPath(), "url"); request.setMaxRetries(2); request.startUpload(); //Starting the upload } catch (Exception exc) { Toast.makeText(this, exc.getMessage(), Toast.LENGTH_SHORT).show(); } }

Add this code to your activity class

 @Override public void onClick(View v) { if (v.getId() == R.id.btn_id) { upload_file_multipart(); dialog = new ProgressDialog(this); dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); dialog.setMessage("Uploading photo, please wait."); dialog.setMax(100); dialog.setCancelable(true); dialog.show(); } }

implements SingleUploadBroadcastReceiver.Delegate for your activity and declare as below.

 public class YourActivity extends AppCompatActivity implements SingleUploadBroadcastReceiver.Delegate { private final SingleUploadBroadcastReceiver uploadReceiver = new SingleUploadBroadcastReceiver(); ProgressDialog dialog; @Override protected void onResume() { super.onResume(); uploadReceiver.register(this); } @Override protected void onPause() { super.onPause(); uploadReceiver.unregister(this); } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_images); //your codes } @Override public void onProgress(int progress) { Log.d("PROGRESS", "progress = " + progress); dialog.setProgress(progress); } @Override public void onProgress(long uploadedBytes, long totalBytes) { } @Override public void onError(Exception exception) { } @Override public void onCompleted(int serverResponseCode, byte[] serverResponseBody) { dialog.dismiss(); } @Override public void onCancelled() { }

Here is the SingleUploadBroadcastReceiver class

 import net.gotev.uploadservice.UploadServiceBroadcastReceiver; public class SingleUploadBroadcastReceiver extends UploadServiceBroadcastReceiver { public interface Delegate { void onProgress(int progress); void onProgress(long uploadedBytes, long totalBytes); void onError(Exception exception); void onCompleted(int serverResponseCode, byte[] serverResponseBody); void onCancelled(); } private String mUploadID; private Delegate mDelegate; public void setUploadID(String uploadID) { mUploadID = uploadID; } public void setDelegate(Delegate delegate) { mDelegate = delegate; } @Override public void onProgress(String uploadId, int progress) { if (uploadId.equals(mUploadID) && mDelegate != null) { mDelegate.onProgress(progress); } } @Override public void onProgress(String uploadId, long uploadedBytes, long totalBytes) { if (uploadId.equals(mUploadID) && mDelegate != null) { mDelegate.onProgress(uploadedBytes, totalBytes); } } @Override public void onError(String uploadId, Exception exception) { if (uploadId.equals(mUploadID) && mDelegate != null) { mDelegate.onError(exception); } } @Override public void onCompleted(String uploadId, int serverResponseCode, byte[] serverResponseBody) { if (uploadId.equals(mUploadID) && mDelegate != null) { mDelegate.onCompleted(serverResponseCode, serverResponseBody); } } @Override public void onCancelled(String uploadId) { if (uploadId.equals(mUploadID) && mDelegate != null) { mDelegate.onCancelled(); } } }
