What Is The Syntax To Get A Blobstore Upload Url From Android?

I have Blobstore uploads working for GWT, but now I need my Android app to upload to Blobstore. I saw this post which explains how to upload once I have the URL, but it does not sh

Solution 1:

I have it like this:

Widget.presenter.java:

uploadButton.addClickHandler(newClickHandler() {
 @OverridepublicvoidonClick(ClickEvent event) {
 //init action
 imageService.getBlobStoreUploadUrl(newAsyncCallback<String>() {
      @OverridepublicvoidonFailure(Throwable caught) {
        Window.alert("Oups Error at ImageUploaderPresenter");
      }
      @OverridepublicvoidonSuccess(String result) {
        uploadForm.setActionUpload(result);
        uploadForm.submit();
      }
    }
  });
}

ImageServiceImpl.java:

@OverridepublicStringgetBlobStoreUploadUrl() {
    //Map the UploadURL to the uploadservice which will be called by//submitting the FormPanelreturn blobstoreService.createUploadUrl("/imageUpload");
}
