This article will explain in detail what are the optimization methods of picture loading in Android. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

1. Optimize the quality of static resource files.

Manually compress pictures through a third-party website at https://tinypng.com/

Advantages of server: reduce quality, save server resources client: improve loading speed, save traffic, local resource file quality is small, can reduce App volume, save traffic for users, and occupy less memory of mobile devices.

2. Mobile upload uses libjpeg for image compression (Huffman algorithm, lossless compression), (ios system comes with, only for android developers' reference)

3. Load in the case of weak network

(1) Select the WebP of Google.

Reason: high compression efficiency and better support for android. After using WebP, traffic savings are nearly 25% to 35% compared to images in JPG format.

Compared with the images in PNG format, the traffic saving is nearly 80%. The most important thing is that the image quality has not deteriorated after using WebP.

(2) optimize network requests. At present, the third-party image loading framework Glide is very mature. If there is a better algorithm, you can design your own image download and loading framework. Recommend Glide

4. Loading sequence

App is the first to load images that are suitable for the picture display window. If you need thumbnails, app loads only thumbnail-sized images, users need the highest resolution images, and app loads larger images.
