Android: Is there a way to implement the barcode scanner into an app? [closed]

Can you scan barcodes off phone screen?

Laser scanners cannot scan barcodes displayed on phone screens because light is not reflected back. Mobile phones have anti-reflection technology to prevent glare and they are constantly emitting their own light from their LCD screens.

So I'm working on a project, and I'm wondering if there is a way I can implement the barcode scanner into my android app? So it would go from my app, open the camera and take the "picture", get the info, and go back to my app with that info?
