copied!<p>I am having problem with the preview of the captured pictures. </p> <p>I have set up the ImageView to preview the image in the xml file. Once the picture is taken, i get a save or discard preview of the taken images. </p> <p>I can preview the captured photo in the ImageView only when i capture the photo in Landscape screen mode and declare the orientation as android:screenOrientation="portrait" in the Android Manifest file. I can preview the image in the Image View in portrait view!
