Barcode Scanner

App Barcode Scanner using zxing library and native camera

Architecture

Clean Architecture, app core has 3 modules:

• camera: configure & init native camera, take a simple image preview (NV21 format) and convert to YUV image
• decoder: use com.google.zxing.Reader (PDF417Reader, QRCodeReader...) interfaz to read barcode into YUV image taken by camera
• manager: compose by camera and decoder module. Set an interval to take image from camera and send to decoder for read barcode

Usage

Configure your Reader modifying 'decoderModule' from Koin configuration

val decoderModule = module {
    single<IBarCodeDecoder> { BarCodeDecoderImp(get(), get(), get(), get()) }
    single<Map<DecodeHintType, *>> {
        mapOf(
            Pair(DecodeHintType.TRY_HARDER, true),
            Pair(DecodeHintType.PURE_BARCODE, true),
            Pair(DecodeHintType.CHARACTER_SET, "ISO-8859-1"),
            Pair(DecodeHintType.POSSIBLE_FORMATS, listOf(BarcodeFormat.PDF_417))
        )
    }
    single<Reader> { PDF417Reader() } // Change this for other barcode types
}
