I use a contentchooser to allow the user to choose an image. Once the user selects an image I put the selected image into an ImageView as follows:
B4X:
Sub imageChooser_Result (Success As Boolean, Dir As String, FileName As String)
If Success Then
imagePhoto.Bitmap = LoadBitmap(Dir, FileName)
imagePhoto.Gravity = Gravity.FILL
Else
ToastMessageShow("No image selected", True)
End If
End Sub
This works great the first time, but if you then use the contentchooser to select a different image the app just crashes (blank screen) no errors.
My imageView was added through the designer so no initialize needed and the imageView is declared in Globals.
