In whatsapp application, when we go to: settings --> application manager --> whatsapp --> app info --> notifications There is an option called show settings or a settings button(Nougat only). On clicking that, the whatsapp settings page will be loaded.
Any idea how to do that? or is there any docs available for customizing the settings?
<category android:name="android.intent.category.NOTIFICATION_PREFERENCES" />
adding an intent filter with the above category will add settings option in your app info > notifications page.
