Android Question for Christmas, I've got an ANR ....

[aeropic]

Hi All,

First of all, merry Christmas to B4A community.
On my side, Santa Clauss brought me an ANR on my application

As I did not know what this meant, I've seen on google it is an application not responding... Now the question is: how can I debbug this ?

Here is the log found on Play store.
Am I right to understand the problem occured while trying to use AutoFocus on CameraEx class ?

Cheers
Alain

Yes. Have you checked whether auto focus is supported?

 

[aeropic]

HI Erel,

Not sure... I've used the cameraEX code:

'Calls AutoFocus and then takes the picture if focus was successfull.
Public Sub FocusAndTakePicture
    cam.AutoFocus
End Sub

Private Sub Camera_FocusDone (Success As Boolean)
a01.PictureProgress = False
    If Success Then
        TakePicture
    Else
        Log("AutoFocus error.")
        'ToastMessageShow("unable to focus...", False)
        TakePicture
    End If
   
End Sub

Is it enough ?

 

[Erel]

You can use this check:

If camEx.GetSupportedFocusModes.IndexOf("auto") > -1 Then 'auto focus is supported

 

[aeropic]

You can use this check:

If camEx.GetSupportedFocusModes.IndexOf("auto") > -1 Then 'auto focus is supported

Thanks Erel, I will add this, but if autofocus was not supported wouldn't it give a Java exception rather than an ANR ?

 

[Erel]

It is definitely possible that auto focus is supported on this device. This is the best you can do...
