The MsgBox says: "Photo downloaded(Bitmap): 250x400" Anyone can help me?

F FrankBerra Active Member Licensed User Longtime User Jan 25, 2015 #4 I found the problem. I created the ImageView1 element with the designer and then i initialized it in the Sub Activity_Create with Code: ImageView1.Initialize("") The B4A editor sometimes warns me saying that i shouldn't initialize the object because it is already initialized(?) by the designer. In any case the program runs correctly with no errors. If i comment out the initialization command of ImageView1 everything works fine and the image is correctly loaded into ImageView. That sounds strange for me. Upvote 0

When you initialize the view you are actually creating a new view. So now the variable points to a different ImageView (which is not added to the activity at all). Upvote 0
