Wait For Activity_PermissionResult (Permission As String, Result As Boolean)

where is Activity_PermissionResult() sub?

Thanks for replying drgottjr:
I am following the Erel tutorial and cannot find the Sub Activity_PermissionResult (Permission As String, Result As Boolean). I have tried to see it several times and will not give it away.
Line 31 contains the Wait For call
Find an sub Activity_PermissionResult (Permission As String, Result As Boolean) and paste it but nothing?

It is not needed/expected if you use wait for

I tested your project as shown below. I also exported the full project. It worked for me. Make sure when you are asked for permission, you need to allow it.

B4X:

Sub Globals
    Private rp As RuntimePermissions
End Sub

Sub Activity_Create(FirstTime As Boolean)
'    shared=rp.GetSafeDirDefaultExternal("")
    Dim testFolder As String=rp.GetSafeDirDefaultExternal("test")
    File.WriteString(testFolder,"test.txt", "aaa")
    rp.CheckAndRequest(rp.PERMISSION_READ_PHONE_STATE) 
    Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
    If Result Then
        Dim pid As PhoneId
        Log("device id: " & pid.GetDeviceId)
    Else
        Log("No Permission")
    End If
End Sub

Thanks for your interest, but downloading the zip rp040920 (copy of the code sent) I still have the same message in the Logs and the device does not request permission and aborts its execution.

Welcome to the wonderful world of Google's permissions. There is nothing wrong with the software of item 5. It also works without problems for me. But what strikes me is the phrase "does not request permission". ? This means that RunTimePermission uses a previously given permission or refusal. ? In view of the error message, a refusal is obvious. I suspect that RunTimePermission is based on a previously given refusal (can also have happened with another B4A Example software). What you can do is the following blunt ax method where you erase all given choices without uninstalling B4A-Bridge:

Uninstall B4A Example on the tablet. Please note that different versions of B4A Example may be installed! Remove them all!
Select B4A-Bridge and find the setting "Storage". For example, 10.80 MB is used in internal storage. Select "Erase data" (do not uninstall).
Start b4A Bridge. Choose Enable FTP.
Allow B4A-Bridge to access media and files.
Go to Tools and connect to B4A-Bridge on the tablet.
Choose under cleaning tools (Ctrl-p)
Start the extracted program from item 5

If all goes well, the RunCheckPermission will now be requested and the text file should now be created.

Android SDK is misconfigured. Follow the installation instructions and it will work: https://www.b4x.com/b4a.html

Thanks Erel, reconfigured the installation according to instructions and it worked.
