Support Android's per-app language setting

Android supports per-app language settings (System Settings → System → Languages → App languages).

I understand that the need for this feature is difficult to explain to those who were born in an English-speaking country, English is their native language, or they speak it so fluently that they will not experience difficulties when all communications and interfaces around them are in English. Or in situations when any activity in issue trackers, feedback to developers and, in principle, online cooperation is carried out only in their native language, no matter how Chinese it is. But there are situations when English, as a universal language, continues to remain a foreign language, its daily use causes difficulties, and developers are not very willing to accept bug reports with hieroglyphic screenshots. Be that as it may, per-app language setting is a great feature, supported by absolutely all current Google applications, and becoming a familiar way to customize the appearance of user applications. Imposing non-standard behavior on users in the case of the basic functionality of your application is not a very good practice.

Your description is all about the language itself, but I don't think this feature is about the language at all.

From the third link:

if you have a set of users who are quite fluent in English, Hindi, and Spanish, and they have a news app on their phones and prefer to read the news in Hindi? For their texting app, they prefer Spanish as they have some friends and family who they text with in Spanish. But for ease of access, they still prefer their device to be in English.

This explanation from google doesn't make sense. For an app to support this feature, it must support multi language first, so there must be an in-app language picker. So I think this is what google actually want to say:

Stupid app developers, you are hiding the language picker too deep, users can't find it, they will even do this: System Settings → System → Languages → App languages than digging in your app setting, let me wipe your ass.

For SpamBlocker, I don't see why people would prefer the system setting than the in-app language picker, it's right there in the setting page.

I think it's redundant:

1. The in-app picker does exactly the same thing as the system setting, but easier to find.
2. The app follows the system language by default, there's no need to change it. Per-languange support is usually necessary for social apps, this app is for personal use only.
3. What would happen if a user set the language to A in the app and B in system settings? I'm sure it won't be a problem because other apps do this. It's just unnecessary.

The only difference is that, the system setting also changes the on-screen app label, but I don't think it makes any difference.

Do I miss anything?
