Show Popup Feature on Android 10
Android 10 and higher place restrictions on when apps can start activities (the COL Reminder popup is an activity) when the app is running in the background.
These restrictions help minimize interruptions for the user and keep the user more in control of what’s shown on their screen.
Because of this restriction the “Show Popup” feature does not work anymore.
The system does not allow to show a popup while the app is not used (in front).
The suggested alternative from Google is now to use a “High Priority” notification with an “Fullscreen Intent“.
As you see in the screenshots above (Left = Heads Up, Right = Normal) that the design differences are small.
The heads up notifications buttons are more present and the main difference is that such an notification will not go away until you swipe it UP or tap on a button.
What does this exactly mean:
If I send the notification it will be now a “High Priority” notification with the added Popup.
The system decides if it will show a “Heads Up” notification or the Popup.
Most of the times it will follow this rule:
Screen is ON and you are using the device –> Shows a “Heads Up” notification
Screen is OFF –> Shows the popup and turns on the phone
So if you want to use this new feature on Android 10 you will find it under “Settings” / “Notifications” –> “Show High Priority”
