Why does the bookmark icon still show as "Bookmark" after reloading the page?

Question

Java

When bookmarking through a short news and refreshing the page, the button is still displayed as add to bookmarks, the same happens when deleting from bookmarks, when refreshing the page, the delete from bookmarks button is displayed.
Cache problem?
If so, how can I fix this without disabling the site's shared cache?

Answer 1

Open AndroidManifest.xml and add the following

<activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
</activity>

Answer 2

Can you translate mistakes?
Yet it says:
Launch Error 'app': Default Activity not found
Launch Error 'app': 'MainActivity' is not declared in AndroidManifest.XML

Answer 3

Do this:

[not-group=5]
    [add-favorites] <span title="Посмотреть позже">{favorites}</span> [/add-favorites]
    [del-favorites] <span title="Убрать из списка">{favorites}</span> [/del-favorites]
[/not-group]
