Now we check every barcode we got from the success listener. We first get the image captured from the camera preview by ImageProxy wrapper class image property, then we obtain ImageInput object from fromMediaImage function to pass it to the scanner to analyze it right after.

Note: You can skip specifying the Barcode format to make the scanner more flexible to scan different Barcode formats.īy implementing ImageAnalysis we got to override analyze function and there all the magic happens. Now, what’s happening? in the class constructor, we have 2 callbacks which are going to be invoked once we capture the result, or fail while doing so, and we implement Analyzer Interface from ImageAnalysis class which is considered as a UseCase for our Camera (we are going to see this later in the article) then we create a scanner object and specify the Barcode format that we want to use. No! Don’t feel overwhelmed, it is easy once you get it, thanks to ML kit, implementing this is much easier than other libraries like Zxing Decoder.
