I am learning camera 2 API using google sample code android-Camera2Basic in that i have changed the width and height of AutoFitTextureView to 200 dp and when i capture the picture then i seeing that picture has more focused area than the preview size.
So How can i get the image as in the preview?
Assuming you want the image to be cropped the same way as your preview, which is what I think you are asking, you can use the the SCALER_CROP_REGION which is a field of the Camera2 API CaptureRequest class.
