Android Question Prevent my app to be closed

[Addo]

In newer Android versions i see an apps like YouTube and Google Chrome does not closed if user opened recent apps and clicked, close all apps.

Also in google Chrome app i notice that there is a lock icon showing in the top right corner when i open recent apps.

How do i achieve the same with b4a to prevent my app to be closed if a user choose to close all apps?

Chrome does not closed if user opened recent apps and clicked, close all apps.

I think that is true only if it was the last app displayed, and that it is Android doing it and not the app. I think any app behaves the same.

As you see in the attached image there is a lock icon in the top right corner.. Which is activated by default during installation.

This lock prevents the app from closing with close all apps button.

You can manually activate this lock by holding the app from recent and drag down..
Then the app willl be locked and will not effected by closing all apps.

I am looking for how to activate this lock with b4a without need to do it manually from the user. As Chrome and YouTube does

Where is that screenshot from? Is it on a Chromebook? On Android 10 on my Mi Max 3 I see nothing like that.

I think that feature is Huawei and Xiaomi only. I did not find the app lock on any other device.

I saw a discussion about this lock sense 2017

What does the lock symbol in the top right corner of an Android phone mean? It appears when trying to see recent apps. - Quora

I think it is for android os globally not a manufacturer certain

This feature is/was exclusive to Xiaomi and Huawei phones. I can figure out that you are using a Huawei/Honor device here…
