Having 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
    }

}

Now you'll have appropriate callbacks fired upon successful/unsuccessful upload.
