    Hello, I need help. I have tried differents solutions but I haven't got any idea. I want that when my device power on, an service starts.

    It is an example (In this case, I have tried open my app when my device power on), and when power on, appears .... "crashed".


    --------SERVICE ------
    #Region Service Attributes
    #StartAtBoot: True
    #End Region

    Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.

    End Sub
    Sub Service_Create

    End Sub

    Sub Service_Start (StartingIntent As Intent)

    StartActivity(Main)

    End Sub

    Sub Service_Destroy

    End Sub

    '-----END SERVICE

    I have tried remove "StartActivity(Main)" in de "Service_Start" but, the application crashed too. It is to say, my app also crashed with the service is empty.

    I need help, because I don't know that thing I am doing bad....

    Can you post the error message from the logs?

    Are you compiling your app in release mode?

    When I compile with debug mode, doesn't appears any error because it happens only when I reboot my device, so I can´t obtain any logs after that. How can I obtain this logs?

    In the other hand?... The error can be due to declare some variables in Process_Globals of the other activites? In same of theese activities I have declare variables which types are NotificationBuilder , list, HttpClient, HttpRequest, Object...

    When I complile and open my app works perfectly. If I close my app and after that I open again, works perfectly too. The problem resides in the fact that I can't use a service module with startatboot. I need it for start anothers services which check some data bases of sqlite.

    P.D: Sorry, my English isn't good.

    Thanks, Erel.

    It's been a while but i think i encountered this issue and resolved it by putting a timer in the service and start the activity in the timer tick. I use 10 seconds. Give it a try and see if that makes a difference.

    RESOLVED


    THANKSSSSSSS for your attention. I am very happy. I found the real problem...

    The problem happens because I had declared some variables (of type: NotificationBuilder , list, HttpClient, HttpRequest) in "Process_Globals" of the several activities, but I had problems to detect it because the error doesn't say what was happening, only says (...chrased). The solution was: I have made a Class Module and I have declared all the variables there. Now, my service start when I power on my device perfectly but, at this moment I have to change a lot of things in my app after this changes.

    Thank you a lot.

    When I try to:

    #Region Service Attributes
    #StartAtBoot: True
    #End Region

    I get this message:

    B4A version: 5.02 (1)
    Parsing code. Error
    Error parsing program.
    Error description: Attribute not supported: startatboot
    Occurred on line: 16
    #StartAtBoot: True

    Why?

    did you put that in a service module or just in the main B4A file?
