I am developing an application that monitors the physical activity of user (ON_BICYCLE, RUNNING, WALKING, IN_VEHICLE, STILL, ON_FOOT).
. So far I've tested the app on Samsung (android ver 7-10), Moto (android ver 7-10) and xiaomy phones (android version 8) and it worked Ok even when the screen turns off (in the background).
I recently started testing on Huawei Y6(2018) (emui 8.0.0) and there is a problem when the phone turns off screen and is left without a WIFI network.
If the screen is OFF and phone have WIFI network - application works Ok.
If the screen is ON and phone is without WIFI network - works Ok.
But if the screen is off and the phone loses the WIFI network, application is freezes, no ActivityTransitionUpdates and no onLocationChanged. After that if screen is turned ON or phone again have WIFI network, everything is Ok.
On the phone I set 'Launch' to Manual and IgnoreBatteryOptimisation to Allow.
Has anyone encountered a similar problem?
If your users are using Huawei phones, you can prompt users to add protected applications to your settings to further reduce the probability of service killing. Go to Settings > Battery > Battery Usage > Your App, turn off Management Automatically, enable Auto-launch, Secondary launch, Run in background.
You can also integrate Push Kit, make the notification to users, and show it as foreground.
