Frame-Focusing Scanner on Android

[Jayson1999]

As the Google's API used in Android for barcode scanning only comes with whole-screen scanning. The UI of the barcode scanning shows a focus-frame in the center of the screen, thus indicating users that the barcode in the frame will be detected.

However, in the case like the above screenshot where multiple barcodes are shown in the screen, the barcode reader will have to pick between the 2 barcodes. Therefore, enhancement has been implemented with a sub-class to read only the barcode inside the frame by cropping accordingly to the frame's size. This can help to prevent constantly receiving wrong barcode in the Single-Scan mode where the Activity will close and return the result instantly upon detecting a barcode. The detection may always be too fast for user to be able to single-tap to select the targeted barcode or even try the zoom gesture, so I feel that the enhancement might be helpful in scenarios.

Hopefully this request can be reviewed and thank you for the time.

Hey @Jayson1999 So I got this error when I was building the project!

error: incompatible types: CentralDetector cannot be converted to BarcodeDetector
        CameraSource.Builder builder = new CameraSource.Builder(getApplicationContext(), centralDetector)

Please let me know.

Hi, might need some weekends to look into it. In the meantime, feel free to explore around it and share with me the good news if you have one!

@utsavDave97 Tested mine was working well... Mind sharing your use case and the complete trace log?
