Broken colors in DayNight Theme after loading Admob/Firebase ad

Question

I use Theme.AppCompat.DayNight.NoActionBar theme for my app. When I load adMob interstital some colors are broken in \"night\" mode (i.e. in RecyclerView).

Answer 1

The issue is supposedly caused by the WebView resetting the UI mode, and this can be worked around by instantiating WebView manually.

I haven't seen the issue after doing this (in Application.oncreate() in this particular app):

    if (nightMode != AppCompatDelegate.MODE_NIGHT_NO) {
        Log.d(TAG, "Manually instantiating WebView to avoid night mode issue.");
        try {
            new WebView(getApplicationContext());
        } catch (Exception e) {
            Log.e(TAG, "Got exception while trying to instantiate WebView to avoid night mode issue. Ignoring problem.", e);
        }
    }
    AppCompatDelegate.setDefaultNightMode(nightMode);
