so i need to buy donate version to enable gms? or juz use the free version to use the keep notification only?
gms feature is available on donation version.
Hibernated app:is like frozen app but you can open it from launcher or it can be triggered by outside events (gms"donation",widget,etc.)
What it dose?when an app is hibernated and have a push for example:viber when you have message it wake up(
even on hibernated state), notification appears and after if the phone is not used it go back on hibernated state so if you have keep nofication on plus gms feature..the apps launch and hibernate and they keep the nofication massage on SystemUI even if the service from the app is hibernated again on the feature.
=====
If you use only keep nofication the hibernated app will not launch when you have message you have to open it manually or to be active on the following app
example:you have Facebook you chat, the messages will come normal but if you hibernate Facebook you wont get any new message only when you launch it,but if you had unread messages when you open Facebook and somehow the phone was ide or you hibernate all apps on greenify the notification you have a new message will the there but Facebook service will be gone.
