Get Image from File Storage [Backendless] - backendless

Question

My users upload some images to the FileStorage at Backendless.
This is the upload sequence:
Backendless.Files.Android.upload(image1_scaled, Bitmap.CompressFormat.PNG,
100, "profileImage", "images", new AsyncCallback<BackendlessFile>() {
#Override
public void handleResponse(BackendlessFile response) {
fileMapping.profile_url = response.getFileURL();
Backendless.Data.of(FileMapping.class).save(fileMapping,
new AsyncCallback<FileMapping>() {
#Override
public void handleResponse(FileMapping response) {
toast_error("Image stored");
}
#Override
public void handleFault(BackendlessFault fault) {
System.out.println("ERROR" + fault.getCode());
}
});
}
#Override
public void handleFault(BackendlessFault fault) {
}
});
And that works flawlessly. Now I need to fetch back the image with the API to display it.
So I need to make a BackendlessCollection<FileMapping> userFiles = Backendless.Data.of(FileMapping.class) call to receive the URL back from that table. And then supposedly do a httpRequest with the url to get back the byte data.
What I can't work out is what sort of .find method to use? Do I .findById() ? And if so, what ID do I use? The "path", "name" ,"table" etc?
Could anyone show an example fitting my case here, with a table storing the url's and such?
Thanks.

You'd this something like this (showing sync call for simplicity, but make sure to change it to Async on Android):
BackendlessCollection<FileMapping> fileMappings;
fileMappings = Backendless.Data.of( FileMapping.class ).find();
Iterator<FileMapping> iterator = fileMappings.getCurrentPage().iterator();
while( iterator.hasNext() )
{
FileMapping fileMapping = iterator.next();
Log.i( "MyApp", "file URL is " + fileMapping.profile_url );
}
