When using webview, I found that the response of the app was very slow when starting the fragment with webview for the first time, but it was not equally slow when it was started again

ViewlogcatIt is found that the above operations are only performed when loading for the first time. Is there any way to improve the response speed of opening the webview for the first time?

Webview is also a browser, it needs to download files, and it will be faster with the cache later.

Optimization is nothing more than on-demand loading, compression and the like. Optimizations that can be used in basic browsers can be used here as well.

You can pre-enable webview and set the height and width of 1 pixel, and preload many static resources. Many domestic apps do this, and the user experience is very good.
