问题
I don't want to update to 2.3 (they broke Instant Run for 4.4.4 Devices, now it only works for 5.* and higher)
Just want to hide the notification:
回答1:
Open Android Studio then File -> Settings -> Appearance & Behavior -> Notifications
Then uncheck "Display baloon notifications"
回答2:
File -> Settings (or Android Studio -> Preferences for macOS) -> Appearance & Behavior -> Notifications.
In the Group column you'll find groups like Android Gralde Upgrade Notification and Plugins Updates etc. Just Change the corresponding Popup column to be No popup.
If you are not sure which group you should configure, maybe you can wait until a notification appear, record its title, and then find a group in the preference UI mentioned above which is most related to that title.

it is ok and for android studio you try it : 1.Open the Preferences window by clicking File > Settings (on Mac, Android Studio > Preferences).
2.In the left panel, click Appearance & Behavior > System Settings > Updates.
3.Be sure that Automatically check for updates is checked, then select a channel from the drop-down list (see figure 1).
Click Apply or OK.
happy code!
