Android Question lock app en Android8

[josetecvino]

when I slide my app in Android 8 (HuaweiP20Pro) the app is killed . The same App using Android 7 is not killed.
I don't know if it is an ANdroid problem or and HuaweiP20 problem.
Do know anyone how to solve it?
Thanks

Huawei P20 kills background apps. There's endless amount of threads about it almost every android forum.
It may help if you set battery optimisation setting "Don't optimise"
