minSdkVersion worth of ≥ 21

Add dependencies

}

Add metadata to routinely obtain scanner modules

...

android:worth="barcode_ui"/>
...

we will use ModuleInstallClient API ARRIVE clear verify the scanner module availability and request obtain as a result of Google Play companies

• Configure barcode scanner choices — GmsBarcodeScannerOptions [Optional]

val choices = GmsBarcodeScannerOptions.Builder()
.setBarcodeFormats(
Barcode.FORMAT_QR_CODE,
Barcode.FORMAT_AZTEC)
.construct()

• Take an instance of GmsBarcodeScanner

val scanner = GmsBarcodeScanning.getClient(this)
// Or with a configured choices


val choices = GmsBarcodeScannerOptions.Builder()
.setBarcodeFormats(
Barcode.FORMAT_QR_CODE,
Barcode.FORMAT_AZTEC)
.construct()


val scanner = GmsBarcodeScanning.getClient(this, choices)
