Picasso vs Imageloader vs Fresco vs Glide

Picasso

It is the most widely used amijiroding library in recent years after UIL.

This is a library made by Square, which I love so much

You can call the function intuitively without any setup action.

Glide

This is a library that was developed by Google and released in 2014 after bolly.

When Google acquired the Bump app, it was this Glide that released the image library used in the Bump app.

It is almost identical to the function method used in Picasso (except for some functions).)

This is the library that I personally think has the best performance.(Of course, I use Picasso for some features.)

It also supports thumbnail viewing, GIF loading, and video still viewing functions that are not available in other image loading libraries.

Fresco

This is an image library released on Facebook.

Most recently released of the four libraries (2015/03/26)

However, the disadvantage is that it is still a recently released library, so there are few references and you need to use Fresco's ImageView.

It's hard to decide which one is the best, so you can use it according to each user's taste.

I rarely use UIL Picasso and Glide value ease of use and performance Fresco seems to be focused on streaming images on the web, as it is a library released on Facebook.
