Android Question Wait for RequestPermission=true and then continue

[petr4ppc]

Dear friends, please for advice...

How can check and request permission and after request permission = true will program flow?
I have read, that with function

CheckAndRequest

will program flow.
But I want not flow program while checkandrequest=true - I want wait for permission=true and after this it is possible to flow program.

How can I do this, please?

Thank you very much

See the tutorial: Runtime Permissions (Android 6.0+ Permissions)

You cannot wait until it is true as the dialog will not appear after the user denies access multiple times.

Do you mean that you want the program to pause while the <checkAndRequest> action is being dealt with? If so, I think that you could use something like this ...

Sub Globals
    Dim rp As RuntimePermissions
    Dim permissionResult As Boolean
    Dim permissionResultReceived As Boolean
End Sub

' .... .... .... ....
' .... .... .... ....

Sub WriteFile
    permissionResultReceived = False
    rp.CheckAndRequest(rp.PERMISSION_WRITE_EXTERNAL_STORAGE)
    Do While Not(permissionResultReceived)
            Sleep(10)     
    Loop
    If (permissionResult) Then File.WriteString(File.DirDefaultExternal, "MyFile", "Here is some data")
End Sub

Sub Activity_PermissionResult (Permission As String, Result As Boolean)
    If (Permission = rp.PERMISSION_WRITE_EXTERNAL_STORAGE) Then permissionResult = Result
    permissionResultReceived = True
End Sub

The above code is not required. You should use Wait For instead.

Sub Process_Globals
    Dim RP As RuntimePermissions
End Sub

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 Then
        'Flow program continues if true
        'Call a sub or put your routine here
    End If
End Sub

Brian, Erel, Peter - thank you for your advices.

In Activity Create, I Have on first row:

If FirstTime=True and Phone.SdkVersion>=26 Then Rules

Because I want first SET the Permissions. After this order I have for example this code

       jhw.Initialize()
                 If jhw.Enabled=False Then jhw.Enabled=True

and other codes.

SUB Rules
    Dim rp1 As RuntimePermissions 
    If rp1.Check(rp1.PERMISSION_RECEIVE_SMS)=False Then
        rp1.CheckAndRequest(rp1.PERMISSION_RECEIVE_SMS) 
        wait for Activity_PermissionResult(permission As String, result As Boolean)
        If result=True Then
             ToastMessageShow("OK1",True)
          Else         
             ToastMessageShow("KO1",False)
        End If     
    End If

    Dim rp2 As RuntimePermissions
    If rp2.Check(rp2.PERMISSION_READ_CONTACTS) =False Then
        rp2.CheckAndRequest(rp2.PERMISSION_READ_CONTACTS)
        wait for Activity_PermissionResult(permission As String, result As Boolean)
        If result=True Then
            'ToastMessageShow("OK2",True)
          Else
            ToastMessageShow("KO2",True)
        End If     
End Sub

'and more permissions
    End If

And now my question:
If program goes to RULES sub and in point of

CheckandRequest

of "PERMISSION_RECEIVE_SMS"
then the flow of program is PAUSED? Or program flow to

 jhw.Initialize()

?
It does it mean - program is paused and wait for accept permission or program is flow and not wait for user accapting of permissions?

I think that program flow and not wait for user accepting....its true, please?

Thank you
Best regards

[Peter Simpson]

For starters you don;t need rp1 and rp2, just RP and use it more than once.

The app is paused and waits for permission before it continues...

 

[Erel]

Watch the tutorial. You shouldn't use Check at all.

It does it mean - program is paused and wait for accept permission or program is flow and not wait for user accapting of permissions?

Please don't use bold text for your questions.

Peter and Erel
thank you very much

Erel - I understand I will no use BOLD function.

I did some correction after your advices and after watching tutorial :

    Dim rper As RuntimePermissions

    rper.CheckAndRequest(rper.PERMISSION_RECEIVE_SMS)
    wait for Activity_PermissionResult(permission As String, result As Boolean)

    rper.CheckAndRequest(rper.PERMISSION_READ_CONTACTS)
    wait for Activity_PermissionResult(permission As String, result As Boolean)

    rper.CheckAndRequest(rper.PERMISSION_READ_SMS)
    wait for Activity_PermissionResult(permission As String, result As Boolean)

    rper.CheckAndRequest("android.permission.READ_PHONE_NUMBERS")
    wait for Activity_PermissionResult(permission As String, result As Boolean)

    rper.CheckAndRequest(rper.PERMISSION_READ_PHONE_STATE)
    wait for Activity_PermissionResult(permission As String, result As Boolean) 
    If result=True Then
        ToastMessageShow("OK",True)
    Else
        ToastMessageShow("KO",True)
    End If

but I think that program flow because the app crashed after first accepting of runtime permission


EDIT:
I have solve it. I place permission to the point where I need to use this permission. Realy I think, that program flow if I use solution as described earlier. This is not worked for me.
Thank you for all advices

Your code is still wrong. Example of requesting multiple permissions: https://www.b4x.com/android/forum/threads/handle-multiple-permission-request.94611/#post-598788

Note that you should always post the error message...
