Android - How can I upload multiple files in one request

Question

I wanted to upload multiple files in one request. I can upload file to server, but I cann't upload more then one file. here is my code

try { String uploadId = UUID.randomUUID().toString(); uploadReceiver.setDelegate((SingleUploadBroadcastReceiver.Delegate) this); uploadReceiver.setUploadID(uploadId); //Creating a multi part request new MultipartUploadRequest(this, uploadId, UPLOAD_URL) .addFileToUpload(path, "p_url[]") .addParameter("phone_number", phone_number) .addHeader("Authorization", "Bearer " + token) //Adding token .setNotificationConfig(new UploadNotificationConfig()) .setMaxRetries(2) .startUpload(); //Starting the upload } catch (Exception exc) { Toast.makeText(this, exc.getMessage(), Toast.LENGTH_SHORT).show(); }

I try to upload image files. This is start image picker

 ImagePicker.create(this) .folderMode(true) // set folder mode (false by default) .folderTitle("Folder") // folder selection title .imageTitle("Tap to select") // image selection title .single() // single mode .multi() // multi mode (default mode) .limit(10) // max images can be selected (999 by default) .showCamera(true) // show camera or not (true by default) .imageDirectory("Camera") // captured image directory name ("Camera" folder by default) .origin(images) // original selected images, used in multi mode .start(PICK_FILE_REQUEST); // start image picker activity with request code

And Activity result

if (requestCode == PICK_FILE_REQUEST && resultCode == RESULT_OK && data != null) { filePath = data.getData(); images = data.getParcelableArrayListExtra(ImagePickerActivity.INTENT_EXTRA_SELECTED_IMAGES); StringBuilder sb = new StringBuilder(); for (int i = 0; i < images.size(); i++) { Log.d("____IMAGES_____", images.get(i).getPath()); } }

Log show this information

D/____IMAGES_____: /storage/emulated/0/DCIM/ios-logo1.png D/____IMAGES_____: /storage/emulated/0/DCIM/Screenshot_1491908860.png D/____IMAGES_____: /storage/emulated/0/DCIM/product_4.png

And I try to send multiple file like this

try { String uploadId = UUID.randomUUID().toString(); uploadReceiver.setDelegate((SingleUploadBroadcastReceiver.Delegate) this); uploadReceiver.setUploadID(uploadId); //Creating a multi part request new MultipartUploadRequest(this, uploadId, UPLOAD_URL) .addFileToUpload(path1, "p_url[]") .addFileToUpload(path2, "p_url[]") .addParameter("phone_number", phone_number) .addHeader("Authorization", "Bearer " + token) //Adding token .setNotificationConfig(new UploadNotificationConfig()) .setMaxRetries(2) .startUpload(); //Starting the upload } catch (Exception exc) { Toast.makeText(this, exc.getMessage(), Toast.LENGTH_SHORT).show(); }

It is work fine, but I choose files with file chooser. And files count will be dynamical. Above code I get files count static. User selected files, and my programm must to upload all of them

are u lopping through file count??

What you can do is make the object of MultipartUploadRequest and looping through your files to upload you can add the files to that object.

MultipartUploadRequest request = new MultipartUploadRequest(this, uploadId, UPLOAD_URL); for(int i=0; i<filesToUploadCount; i++){ //change path and data according to your files request.addFileToUpload(pathForFile, "p_url[i]"); } request.addParameter("phone_number", phone_number); request.addHeader("Authorization", "Bearer " + token); //Adding token request.setNotificationConfig(new UploadNotificationConfig()); request.setMaxRetries(2); request.startUpload();
