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.

   

2. Specify the template file via setTemplateFile

   • Java
   • Kotlin

   1.  BarcodeScannerConfig config = new BarcodeScannerConfig();
       config.setTemplateFile("ReadQRCodes.json");
      

   2.  val config = BarcodeScannerConfig().apply {
      templateFile = "ReadQRCodes.json"
       }
