I have a camera preview in my android app. As you all probably know it is implemented by a surfaceview in android.
In my photo app, which allows users to take pictures, I want to blur the camera preview (the surface view) if the user has not logged in yet if the user is logged in, I will display the normal preview (without blur)
Blur as something like
But there seems to be no way to do it
Couple things come to mind but I am not sure how to achieve it
- use a blur overlay and place it on top of the surface view, but how do u create such blur overlay?
another approach is to change the attribute of the window, but I can't do it to
surfaceview,getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
So can we create a window overlay the surfaceview and set the flag like that? I don't think so
can someone tell me how to blur a camera preview, which is a surface view
note: I am trying to blur an area which is the output from camera preview, so it is not like I am blurring a static image, the blur area will change depending on where you point your phone camera
