Android Question How to let "CheckAndRequest" run before Starter service starts?

[flylg999]

This is my first post,Thank you for your help.
When the app is about to run,
it will crash because there is no storage permission

in the main

Sub Activity_Create(FirstTime As Boolean)
rp.CheckAndRequest(rp.PERMISSION_WRITE_EXTERNAL_STORAGE)
    Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
    If Result = False Then
        ToastMessageShow("..........", True )
        Sleep(1000)
        ExitApplication
    End If
 
...........


End Sub

in the starter.bas

Sub Service_Create   
 Dim dir As String
        dir = File.DirDefaultExternal
        If  Not (File.Exists( dir, "sd.db")  ) Then
            File.Copy(File.DirAssets, "sd.jpg",  dir, "sd.db" )
        End If
        SQL1.Initialize( dir, "sd.db", True)
End sub

Welcome to the forum!

There are several mistakes here.

1. Service_Create of the starter service is run before the permission is requested.
2. You don't need a permission at all. Watch the runtime permissions video tutorial and it will be clear.
You need to use RuntimePermissions.GetSafeDirDefaultExternal.

3. I would have used File.DirInternal instead. Save yourself crashes that will happen when the secondary storage is not available.

4. Use DBUtils. It will help you: https://www.b4x.com/android/forum/threads/b4x-dbutils-2.81280/
There is a method named CopyDBFromAssets which you can use.
