Android Question runtimepermissions strange behaviour

[Hamied Abou Hulaikah]

        Dim rp As RuntimePermissions
        For Each permission As String In Array(rp.PERMISSION_GET_ACCOUNTS,rp.PERMISSION_READ_CONTACTS)
            rp.CheckAndRequest(permission)
            Wait For B4XPage_PermissionResult (permission As String, Result As Boolean)
            If Result = False Then
                Log(permission & " denied")
                Return
            End If
        Next

In B4XPages, above code works fine if we don't grant it, Log(permission & " denied") fired.
If we grant it and call it again, code crash & through error:

Sub activity_permissionresult was not found.

Any explanation?

 

[drgottjr]

nothing strange going on; activity_permissionresult is hardcoded in the runtimepermissions.class. that's what it wants, that's what it's looking for, not B4XPage_PermissionResult

 

[Erel]

That's incorrect.

You are using an old version of RuntimePermissions. Delete it from the internal libraries folder and reinstall B4A.

 

[drgottjr]

talkin' to me? or him? i'm running runtimepermissions 1.12 on b4a 11.50 from 21.03.2022. internal only. should i be using something else?

 

[Erel]

My answer was indeed not clear.

The correct signature in B4XPages projects is:

Wait For B4XPage_PermissionResult (permission As String, Result As Boolean)

Based on the error posted in the question, either the OP modified the template code in the Main module or the OP uses an old RuntimePermissions library.

 

[Hamied Abou Hulaikah]

Nothing modified, runtimepermissions lib 1.12
Can you check the attached example, please.
After you run it: grant the permission, After that click again on button, app will crash!

 

[Sandman]

Any explanation?

I'm just curious, could you please let us know what brand and model your phone is? Also the OS version?

 

[Hamied Abou Hulaikah]

Samsung Note 9
OS 9 Pie

 

[agraham]

Your example works fine for me with repeated button presses and no error on all the devices I have readily to hand
Samsung Tab A 8 2019 with Android 11
Redmi Note 9 Pro and Android 11.
Microsoft Surface Duo and Android 11.
Google Pixel 4a and Android 12.

 

[Hamied Abou Hulaikah]

Did you mean Android os 9 is the problem?

 

[agraham]

Did you mean Android os 9 is the problem?

No. I'm just checking your example as you asked. What conclusions you draw are up to you.

 

[Hamied Abou Hulaikah]

My doubt increased! this work fine, why OP not work!

    Dim rp As RuntimePermissions
    For Each permission As String In Array(rp.PERMISSION_GET_ACCOUNTS,rp.PERMISSION_READ_CONTACTS)
        If rp.Check(permission)=False Then
            rp.CheckAndRequest(permission)
            Wait For B4XPage_PermissionResult (permission As String, Result As Boolean)
            If Result = False Then
                Log(permission & " denied")
                Return
            End If
        End If       
    Next
    Log("You are here")

Is CheckAndRequest has internal problem?

 

[agraham]

Is CheckAndRequest has internal problem?

Very unlikely. It's been working with no problems for lots of other people for several years.

 

[ivan.tellez]

Runtimepermissions strange behaviour, I was about to ask about this very same problem.

No. I'm just checking your example as you asked. What conclusions you draw are up to you.

It is not the code, I tested your "B4XPages enhanced example" and it had the exact same behavior that OP describes.

You are using an old version of RuntimePermissions. Delete it from the internal libraries folder and reinstall B4A.

Looks like there is a problem with the way internal libs are updated. The version in the IDE was 1.12 but still the old behavior. I deleted the Install folder, reinstall B4A and it is working with pages now.

Maybe the file RuntimePermissions.androidx.jar was the problem

Any explanation?

Did you try the proposed solution by Erel? Do you have a RuntimePermissions.androidx.jar file in your internal libs?

the OP uses an old RuntimePermissions library.

Could the installer be improved to delete this obsolete files?

 

[Hamied Abou Hulaikah]

Do you have a RuntimePermissions.androidx.jar file in your internal libs?

No

 

[Erel]

1. Delete all the internal libraries.
2. Reinstall B4A.

 

[Hamied Abou Hulaikah]

1. Delete all the internal libraries.

I have a lot of additional files inside it, if I deleted it, I'll missed these files (but I can overcome this problem).

Could the installer be improved to delete this obsolete files?

Yes, It is better to improve installer for next releases to be smooth and silent.

 

[Erel]

I have a lot of additional files inside it, if I deleted it, I'll missed these files (but I can overcome this problem).

This is a big mistake. You shouldn't copy libraries to the internal folder. This is exactly the purpose of the additional libraries folder.

 

[Hamied Abou Hulaikah]

This is a big mistake. You shouldn't copy libraries to the internal folder. This is exactly the purpose of the additional libraries folder.

Yes, it should not be touched manually, But older B4A versions was not has additional libs folder, I was add any new libs to it. I'll solve this. thanks

 

[Erel]

But older B4A versions was not has additional libs folder

Not true. It was there since B4A v1.0.
