Can I use html5 cache manifest on android webview?

Question

Chrome desktop shows a message warning on console about deprecation and end of support when using a manifest appcache:

[Deprecation] Application Cache API manifest selection is deprecated and will be removed in M82, around April 2020. See https://www.chromestatus.com/features/6192449487634432 for more details.

But there is no deprecation warning on the methods documentation to enable appcache on a webview: https://developer.android.com/reference/android/webkit/WebSettings#setAppCacheEnabled(boolean)

Will the use of manifest cache be deprecated also on android webviews? Is there a deadline to adapt the application?

Answer 1

We should not use this anymore. It was very simple and useful but this is now a big no no.

This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes.

You should consider using Service workers instead.
