Well, before you can list your files from URL, you need to download them. Check this link, it will help you properly download your images, then you'll have to just show them where you want.

Currently I want to make a list like pictures and images on the server when I click on it, it will download the images to the memory device. If the image is downloaded, it will not download again and the image that is not there will be downloaded. Then I want to ask for a solution from everyone, how should I handle the download to be clean and good for performance. Or do you have an example for me to refer to? Thank you!
There are some ways to find out if your image already exists in your phone storage but the best way to find it out is by image name, compare image names before downloading.
I'm trying to find simplest solution to make app where I can download all the images from the specifed, hardcoded directory.
So far, my idea is to get list of all .jpg images (since it will be the only image format in this directory) and put it in places on ViewPager so each image will be on seperate page.
Anyone has nice snippet or friendly library to use to make it happen?
You can create a txt file on the server in which the URLs of all images will be kept; then program your app to download this file first; then use input stream to read the URLs from the file and create a loop to download all urls until they finish, by checking if the input is null.
On server side either add the urls manually to the file or write a JavaScript to automatically write the URLs when uploading the image.
I am using .net web services and I am having list of folders and files. I am successful in retrieving list of files(.jpg Image, .pdf, .TIF) but can anybody let me know how we can open .jpg, .pdf, .tif or other files format which I am getting from web services. Is there any specific code to open particular format or we can use path (/) to open that particular file?
Thanks.
if you need to download and display an image, check my answer on this post, that is probably what you are looking for. Common extensions for displaying images in Android are .png and .jpeg, you will not be able to show a .pdf file using an ImageView. You can also use the method mentioned in my answer inside an AsyncTask to perform the download in background and then update your UI thread
i got the following problem. I want to downlaod multiple images and display them into a gridview or gallery. I managed to download a single image from a specific address.
For example: "www.example.com/images/image1.jpg"
Now i want to download all images located at the root address "www.example.com/images/" but i dont know the names of the images, so i dont know the specific address for every image.
Would be nice if someone can help me with that.
if a html page references the images or the /images/ folder contents are visible in a web browser you could use wget or curl to retrieve the images. This in itself is another programming issue. WGET or CURL
To say it's not possible is like giving up.
Anything is possible :)
I am running a web server and storing all my photos at a folder called photos. Now I want the android application to list all the photos under that particular folder(It can be a slide show or a grid view). I know how to load an image from a url . But I am really unsure about how to view all the images stored on a folder. Could someone please point me in the right direction.
Refer this for load web images in gridview
And this to load images from web by lazylist.
To get list of images from your folder. You need to read all file names in that folder by using FTPClient and put the filenames as url in the above method.
