Android Question Start at boot a foreground service

[Maciej]

Hello,

I’m trying to start at boot a foreground service. I’ve double checked everything:

1.Service Attribute #StartAtBoot is set to True

2.Project Attribute #CanInstallToExternalStorage is set to Fase

But the service is not started on boot (Android 4.2.2)

Am I missing something ?

BR,

Maciej

How do you know it it not starting?

 

[Maciej]

In Sub Service_Create I create the file and write into it.
Actually the file is not created.
I also raise a notification which is not displayed.

Can you check the logs and see if the service is created message is being shown?

It could be that you are attempting your write operation before memory is fully initialized. Below is a sub that I wrote for a situation similar to yours. Don't attempt your write until it returns mounted

'returns state of DirDefaultExternal - unmounted, mounted or shared
Public Sub myStorageState As String
    Dim r As Reflector   
    Dim ExternalStorageState As String=r.RunStaticMethod("android.os.Environment", "getExternalStorageState",Null,Null)
    Log("[myStorageState] -- Storage state is:  " &ExternalStorageState)
   
    Return ExternalStorageState
   
End Sub

I also raise a notification wich is not displayed ...

What do you mean by check the log ?

I generate an APK which I install on the device, and then I reboot it.

The device is not connected to my development PC …

But you start your app at least once after installing before rebooting?

I just thought that myself as I read down the thread....

It seems that launching the app once before rebooting solves the issue. I wonder why ?

Things like StartAtBoot becomes ACTIVE when you first start the App after Installing. Just installing the app does not make the StartAtBoot active. The App must be started at least once.

check that fast boot is disabled if such a feature exist's on your device. I had the same issue on a HTC on X. I would recommend a timed delay of about 20 seconds in the boot service before you initialize your storage to allow storage to be initialised.

Agreed. This is why I check memory init status on boot with the sub above. It seems that otherwise, app code begins to execute before external data memory is available for file operations.
