something similar to SDWebImage in iOS for Android?

Question

I was looking for something similar to SDWebImage for Android. What SDWebImage does in iOS is this:

load images from URL, uses cache, does asynchronous downloading.

I am looking for something similar for Android. Any hint ?

Thanks.

Answer 1

Something simple that I'm using for a project is called Picasso:

https://github.com/square/picasso

I use SDWebImage in my iOS side of the project and Picasso is just as easy.

Answer 2

At Applidium, we recently ported SDWebImage to Android. It's called Shutterbug, and it does everything you asked for.

Here is a link to the project: https://github.com/applidium/Shutterbug . Enjoy!

}

Hope it helps.

https://github.com/thest1/LazyList

A simple library to display images in Android. Images are being downloaded asynchronously in the background. Images are being cached on SD card and in memory. Can also be used for GridView and just to display images into an ImageView.

Something to keep in mind, this will create a folder on the SD card called LazyList, but since it is open source you can change the name easily. This was built with lists in mind, however you can just as easily use it anywhere.
