Android Question Service swipe out of app tray

jayel · Jun 22, 2015

Hello,

I have an app that runs a service with a websocket.
Now when I push the button that shows all the apps that are running, i swipe out my app and the pauze event fires with userclosed true, there I close my service.(normal)

When i push the home button the pauze event fires with userclosed = false (normal)

But when I push the button to show all my running apps and swipe out my app (close the app). No event get fired, so I cannot close my service and I get a message "appname stopped".

Greets,

John

Are you using a foreground service? If not then the process will be killed immediately when the user swipes it out of the recent apps. You should check the logs and see why your app is crashing after it was killed. It shouldn't.

Are you testing it in Release mode? Are you using usb debug mode?

jayel · Jun 22, 2015

in debug mode (wifi)

Erel · Jun 22, 2015

The process is killed and then the OS tries to recreate it. However as it is a debug build it cannot start. You should test it in release mode.

Note that you can only see the logs in debug mode when connected with B4A-Bridge.

I have following on top of my service :

B4X:

#Region  Service Attributes
    #StartAtBoot: false
    #StartCommandReturnValue: android.app.Service.START_STICKY
#End Region

Could this affect something?

It will not cause your app to crash. It will cause the process to be restarted. I guess that you are accessing something that was not initialized because the main activity was not created.
