"zxing Barcode" scanner is successfully working in my App
https://github.com/journeyapps/zxing-android-embedded
I want to open the scanning screen (i.e., Intent), on same Activity in the center in a small window
How can I get this type of Interface ?
You may use Journey's Library. You can use the scanner as a component just like an image or a text. It's based on ZXing. =)
