Improve the Performance of BarcodeScanner

Using a template file is the quickest way to improve the performance of BarcodeScanner. A template file is a JSON file (or JSON string) that includes a series of algorithm parameter settings. Contact us to get a customized template for your scanner.

  1. Add a Templates folder to the assets folder of your project at src\main\assets\Templates. Put your JSON file in the Templates folder. Here we use a ReadQRCode.json file as an example.

    initSettings

  2. Specify the template file via setTemplateFile

    >- Java >- Kotlin > >1. ```java BarcodeScannerConfig config = new BarcodeScannerConfig(); config.setTemplateFile("ReadQRCodes.json"); ``` 2. ```kotlin val config = BarcodeScannerConfig().apply { templateFile = "ReadQRCodes.json" } ```
