Android Question endless loop in check permission

[dcoun]

In the main activity I have a sub that it is call by a resumable sub initiated by the activity_resume
It runs the command Starter.rp.CheckAndRequest(Starter.rp.PERMISSION_READ_EXTERNAL_STORAGE)
in the Sub Activity_PermissionResult I have only a Log("perm: "&Result)
Any idea why I never see the permission window and I can see only the following in the logs


perm: false
** Activity (main) Resume **
main resume
true
** Activity (main) Pause, UserClosed = false **
sending message to waiting queue (activity_permissionresult)
running waiting messages (1)
perm: false
** Activity (main) Resume **
main resume
true
** Activity (main) Pause, UserClosed = false **
sending message to waiting queue (activity_permissionresult)
running waiting messages (1)
perm: false
** Activity (main) Resume **
main resume
true
** Activity (main) Pause, UserClosed = false **
sending message to waiting queue (activity_permissionresult)
running waiting messages (1)
perm: false
** Activity (main) Resume **
main resume
true
** Activity (main) Pause, UserClosed = false **
sending message to waiting queue (activity_permissionresult)
** Activity (main) Pause, UserClosed = false **

It is a mistake to have an Activity_PermissionResult sub. You should use Wait For. It is simpler.

It is hard to say anything else as you haven't posted the code.

Change it to not have any resumable subs.... The same results. Code follows:

Sub Activity_Resume
Log("main resume")
GetReady
End Sub


Sub Activity_PermissionResult (Permission As String, Result As Boolean)
    Log("perm: "&Result)
End Sub

Sub GetReady
    Starter.rp.CheckAndRequest(Starter.rp.PERMISSION_READ_EXTERNAL_STORAGE)
End Sub

With the following code I get:

    Starter.rp.CheckAndRequest(Starter.rp.PERMISSION_READ_EXTERNAL_STORAGE)
    Wait For PermissionResult (Permission As String, Result As Boolean)

** Service (starter) Start **
** Activity (main) Create, isFirst = true **
maincont
** Activity (main) Resume **
main resume
true
*** Service (httputils2service) Create ***
** Service (httputils2service) Start **
** Activity (main) Pause, UserClosed = false **
sending message to waiting queue (activity_permissionresult)
running waiting messages (1)

I recommend you to watch the video tutorial. There are many mistakes in the code you posted.

I corrected the Wait for but I can not find the "many mistakes"
Thank you in advance

The code now is:

    Starter.rp.CheckAndRequest(Starter.rp.PERMISSION_READ_EXTERNAL_STORAGE)
    Wait For Activity_PermissionResult (Permission As String, Result As Boolean)

In the manifest I entered
AddPermission(android.permission.PERMISSION_READ_EXTERNAL_STORAGE)

and the problem continues
I can not find anything else in the tutorial

** Activity (main) Resume **
main resume
true
** Activity (main) Pause, UserClosed = false **
sending message to waiting queue (activity_permissionresult)
running waiting messages (1)
perm: false
** Activity (main) Resume **
main resume
true
** Activity (main) Pause, UserClosed = false **
sending message to waiting queue (activity_permissionresult)
running waiting messages (1)
perm: false
** Activity (main) Resume **
main resume
true
** Activity (main) Pause, UserClosed = false **
sending message to waiting queue (activity_permissionresult)
running waiting messages (1)
perm: false
** Activity (main) Resume **
main resume
true
** Activity (main) Pause, UserClosed = true **

I think this thread should be moved to bugs:
Create a new project, select library runtimepermissions
Change only the following code:

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

End Sub

Sub Activity_Resume
        rr.CheckAndRequest(rr.PERMISSION_READ_EXTERNAL_STORAGE)
        Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
        Log("perm: "&Result)

End Sub

If I run it, it shows:

running waiting messages (1)
perm: false
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **
--------- beginning of system
sending message to waiting queue (activity_permissionresult)
running waiting messages (1)
perm: false
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **
sending message to waiting queue (activity_permissionresult)
running waiting messages (1)
perm: false
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **
sending message to waiting queue (activity_permissionresult)
running waiting messages (1)
perm: false
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **
sending message to waiting queue (activity_permissionresult)
running waiting messages (1)
perm: false
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = true **

To be honest I can not understand why this happen
