Currently I am not having server to upload the images and the images will be twice time if i copy images assets to sdcard, so I put all images in assets folder.The size of images are large, it takes time to decode and scale images.
I want to use lazy loading to show theses images.But I can use lazy loading code only when images are coming from sdcard or web server.
Please suggest me how can i show images from assets folder with smooth scrolling.
Thanks in advance.

You can use lazy loading with any source. Are you using an existing implementation, or did you create your own? If you have the code, you can easily extend it so that it allows loading images from assets.

Try it with Cache? Best way to do this:

Volley gives you a NetworkImageView, this is a "normal" ImageView, but you can give it a URL and volley will do all the rest for you (download, or load from cache, if already loaded).
I'm currently working on an application in college. I have created several games incorporating lots of images. My lecturer however is not happy with the app loading the images from the drawable folder, he wants something more efficient on memory.
Just wondering if anyone knows any solution? i looked at lazyloader and asychronous loading but most examples use images from the web. I need an efficient way to load lots of high quality images from drawable folder to UI.
Here is your options:
Load images from drawable as is now
Reduce images size and use lower quality JPEG for mobile
Create download class and download images from server to SD card and use it from there
If you using images in your app, you can read them from drawable, SD card or online. The image have to be somewhere to load it.
When i develop a android app with download and caching image from internet, i see many app use MemoryLruCache or DiskLruCache to cache image after download. But i want to know why they use them, why don't use the way like: download image, then save image into sd card and after get image from sd card to show it( it is manual way).
I'm newbie in android dev. So please help me to understand it?
Thanks many many times.
well downloading a list of images from url will consume time and also fill up the user memory also....so its better to dynamically load images from url and make its cache and then preview the images from cache..
I hope you did got my point....check some example of lazy loading of image
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.

Thanks in advance.
Go with the solution Lazy loading list with images because it does the same trick that you require. i.e. download image once, store it in cache and display as and when it requires.
go thorugh this example given at GitHub: https://github.com/thest1/LazyList
store your images in sdcard.check wheather your images exist in sdcard or not if yes simply display those images otherwise download from web and store in sdcard,display from sdcard
