Why SQLite to ImageView, BitmapFactory.decodeByteArray Returning Null Android Studio? : I'm developing a contacts app with a photo. I have Store and retrieve data from SQLite and it's working fine on my list view.

The problem is when I click a list item from it's supposed to show an image view and few other details. but the image is not showing on the Activity 

[List View on Main Activity ][1]


[In the empty space here should be an image of the contacts][2]
