Android Question Bluetooth Disconnected on Close?

[Taylor Chapman]

Hi there,

I am currently running bluetooth using asyncStreams. Whenever the user minimizes the application (ex. returns to the home screen) and then goes back into it, the bluetooth connection seems to terminate.

Is this the expected behavior?

EDIT: It's probably worth mentioning that I am running the connection in a service.

Thanks!
Taylor

Android can kill the process when the app is in the background. You can call Service.StartForeground to prevent it.

Hi Erel, thanks for your reply!

I've added the following to Sub Service_Create

    nNotify.Initialize
    'nNotify.Icon = "logoCut.png"
    nNotify.Icon = "logoCut"
    nNotify.SetInfo("Bent Remote", "Tap to open.", Null)
    nNotify.Sound=False
    nNotify.Vibrate=False
    nNotify.Light=False
    nNotify.OnGoingEvent=True
    Service.StartForeground(1,nNotify)

However whenever the user closes the application, Sub AStreams_Terminated runs and the connection is closed. Any ideas as to why this might be?

Thanks,
Taylor

How are you closing the app?

 

[Taylor Chapman]

By clicking the "home screen" button on the tablet.

Make sure that it is not your code that closes the connection. The connection should not break in this case.

I've noticed that the service doesn't appear in the Android tablet status bar - is it supposed to? If so, any ideas as to why it wouldn't appear?

Thanks

It should show after you call Service.StartForeground.
