Chromium on Web Access Favicon

Source: Internet
Author: User

Each page has a favicon, which is required for the history to be saved. In the content directory, this is not implemented.

Here's my implementation process:

There are methods in the file: Webcontentsimpl::onupdatefaviconurl

This method is the response method of browser process after the kernel resolves to favicon, after giving feedback to Chromium's browser process.

The implementation of this method is as follows:

For_each_observer (Webcontentsobserver, Observers_,
Didupdatefaviconurl (page_id, candidates));

The observer here is

I add the following method in

void Shell::D Idupdatefaviconurl (Int32 page_id,
Const std::vector<faviconurl>& candidates) {
Updatefaviconurl (page_id, candidates);

Then, add the following method in the file:

void Shell::updatefaviconurl (Int32 page_id,
Const std::vector<faviconurl>& candidates) {
jnienv* env = Attachcurrentthread ();
Gurl Favicon_url = Candidates.back (). Icon_url;
scopedjavalocalref<jstring> J_favicon_url = base::android::convertutf8tojavastring (env, Favicon_url.spec ());
Return Java_shell_updateshellfaviconurl (env, Java_object_.obj (), j_favicon_url.obj ());

That way, can get Faviicon.

private void Updateshellfaviconurl (String faviconurl) {
Mshellfaviconurl = Faviconurl;
