Android Question Intent Based Camera - Taking photo with confirm screen

[rleiman]

Greetings,

I'm experimenting with the intent based camera by Erel and would like to alter this code in TakePicture so the confirmation screen with "Ok" and "Retry" is not displayed so execution goes directly to ion_Event.

Truly,
Emad

Sub TakePicture
    Dim i As Intent
    i.Initialize("android.media.action.IMAGE_CAPTURE", "")
    File.Delete(imageFolder, tempImageFile)
    Dim p As Phone
    Dim u As Object
    If p.SdkVersion < 24 Then
        Dim uri As Uri
        uri.Parse("file://" & File.Combine(imageFolder, tempImageFile))
        u = uri
    Else
        u = CreateFileProviderUri(imageFolder, tempImageFile)
    End If
    i.PutExtra("output", u) 'the image will be saved to this path
    Try
        StartActivityForResult(i)
    Catch
        ToastMessageShow("Camera is not available.", True)
        Log(LastException)
    End Try
End Sub

'result arrives here
Sub ion_Event (MethodName As String, Args() As Object) As Object
    If Args(0) = -1 Then
        Try
            Dim in As Intent = Args(1)
            If File.Exists(imageFolder, tempImageFile) Then
                lastPicture = LoadBitmapSample(imageFolder, tempImageFile, ImageView1.Width, ImageView1.Height)
                ImageView1.Bitmap = lastPicture
                
                Dim Out As OutputStream
                Out = File.OpenOutput(GetExternalStoragePublicDirectory("DCIM") & "/Camera", "Emad.jpg", False)
                
                lastPicture.WriteToStream(Out, 100, "JPEG")
                Out.Close

            Else If in.HasExtra("data") Then 'try to get thumbnail instead
                Dim jo As JavaObject = in
                lastPicture = jo.RunMethodJO("getExtras", Null).RunMethod("get", Array("data"))
            End If
        Catch
            Log(LastException)
        End Try
    End If
    If lastPicture.IsInitialized Then ImageView1.Bitmap = lastPicture
    Return Null
End Sub

The example was updated and it is based on FileProvider class. You should update your code.

You cannot use the intent based method to take a picture without the user confirmation.

Hi Erel,

Can I change the coding so a "Cancel" button in included on the confirmation screen?

Thanks.

You don't have any control over the camera app. The intent just starts a camera app (there could be many different types of camera apps) and returns the taken image.
