Android Question Need android.permission.BLUETOOTH_CONNECT permission for AttributionSource

[Filippo]

Hi,

in the Firabase have some users with this error message(see title). Most of the phones are Samsung, one of them is a Samsung Galaxy A13(Android 12).
To be able to reproduce the same error, I even bought a new Samsung Galaxy A13 today also with Android 12.

Result ..., I still can not reproduce the error.

Does anyone perhaps still have a tip?

[B4XPages] Bluetooth Chat Example

Updated implementation, based on B4XPages of https://www.b4x.com/android/forum/threads/android-bluetooth-bluetoothadmin-tutorial.14768/#content. The code is much simpler compared to the previous example. Note that you can call Serial.Listen without making the device discoverable. This is useful...

UPDATE your application and add the new permission.

I have already done all that.
All my test devices with Android 8, 10, 12 work without problems.

In my app, when I exit, I use the "ExitApplication" function.
Is it possible that the problem is caused by this function?
In the Google Play console I found this crash report:

Exception java.lang.SecurityException:

        CallSub(Starter, "Service_Stop") 'StopService(Starter)
        
        ExitApplication
    End If
End Sub

Bluetooth-Class:
Public Sub DestroyConnection

    if ble.IsConnected Then
        ble.DestroyConnection
    End If
    If admin.IsInitialized Then
        admin.Disable
    End If
End Sub

 

[Erel]

It looks like a permission issue related to the admin.Disable call.

Hi Erel,
Can you imagine how to fix the problem?

Hi Erel,

You can check if the app has permission before disabling it.

 

[Filippo]

You can check if the app has permission before disabling it.

I think that it is not logical.
If I have permission to enable, then I must also have permission to disable.

 

[Filippo]

I believe that the problem has to do with the "ExitApplication" function, because the app does not exit properly.
Here is the log output with and without "ExitApplication":

'logs without "ExitApplication"

** Activity (main) Pause, UserClosed = true **
admin.Disable
Starter: Service_Stop
** Service (starter) Destroy (ignored)**
** Service (httputils2service) Destroy **


'logs with "ExitApplication"

** Activity (main) Pause, UserClosed = true **
admin.Disable
Starter: Service_Stop

So, according to these 2 links below, it's a bug in Api 31.

Hi,

you have to check if admin is enabled, if yes, then it can be deactivated.

    If admin.IsInitialized And admin.IsEnabled Then
        admin.Disable
    End If
