I have tried the codegen-sample. But what I really want is to show all the folders, subfolders and contents inside it and not just images. I have searched for many hours for a complete tutorial for these and not just the method of directory listing(with the setOnClickListener and showing it to ListView and everything). I’m really sorry if I’m being a nuisance but I’m really new to backendless and I can’t fully understand the documentations. And there are not much Video Tutorials. I’m using backendless for research purpose for my study.
I would really appreciate the help.
Francis,
The problem you’re battling has really nothing to do with Backendless. All you need to “master” is the process of loading a file from a URL. Our API gives you an ability to get a listing of URLs for a remote directory. Once you have those URLs, you need to figure out how to load the content of the file.
A simple search for “how to load file from URL android” in google gives about 15 million results. You can just the links on the first page and get a bunch of samples showing exactly what you need.
Hope this helps.
Mark
Mark Piller,
I’ve been trying to show the list or URLs in my tab.
Backendless.Files.listing("/Uploads", "*docs", true, new AsyncCallback<BackendlessCollection<FileInfo>>() {
@Override
public void handleResponse(BackendlessCollection<FileInfo> fileInfoBackendlessCollection) {
Iterator<FileInfo> filesIterator = fileInfoBackendlessCollection.getCurrentPage().iterator();
while (filesIterator.hasNext()) {
FileInfo file = filesIterator.next();
String URL = file.getURL();
String publicURL = file.getPublicUrl();
Date createdOn = new Date(file.getCreatedOn());
String name = file.getName();
}
}
@Override
public void handleFault(BackendlessFault backendlessFault) {
}
});
}
}
There are no errors but my List of URL’s is not showing.
Have you tried setting a breakpoint on this line for instance, and see if it returns a value?:
String URL = file.getURL();
Also, could post a screenshot of the Uploads folder from Backendless console?
In my android studio the:
String URL = file.getURL();
says the “Variable “URL” is never used”.
That’s right, it is never used. The question is whether the code execution gets there. Setting a breakpoint would help with that.
How come I’m getting this error? I did exactly what was showed on the example in the Directory Listing documentation.
If you are talking about “Variable “URL” is never used”, it is not an error but a warning.
