Integrates multiple scanning protocols into a unified interface, enabling product scanning via camera or barcode methods with easy setup and comprehensive scanning result management.
This library combines various scanning protocols into a single, easy-to-use interface.
Step 1. Add the JitPack repository to your settings.gradle file:
dependencyResolutionManagement {
repositories {
...
mavenCentral()
maven { url 'https://jitpack.io' }
}
}
Step 2. Add the dependency to your app build.gradle:
dependencies {
implementation 'com.github.tillhub:scan-engine:x.x.x'
}
This SDK offers two ways to scan products conveniently:
Camera scanner(SunmiScanner/DefaultScanner) : Manually register an activity or fragment result callback.Barcode scanner(BarcodeScannerImpl) : Register a BroadcastReceiver with the barcode scanner.Singleton Access: Obtain a singleton reference to the ScanEngine instance.Initialization: Create a per Activity or Fragment Scanner instance. SDK will automatically selects the appropriate scanner based on the device manufacturer (SunmiScanner or DefaultScanner).
override fun onCreate(savedInstanceState: Bundle?) {
// ...
val scanEngine = ScanEngine.getInstance(context)
val scanner = scanEngine.newCameraScanner(this)
scannerButton.setOnClickListener {
scanner.startCameraScanner()
}
// Observing scan result with scanEngine
scanEngine.observeScannerResults().collect { scanEvent ->
// Handle scanEvent result
}
}
Here's example of Scanner interface:
interface Scanner {
fun observeScannerResults(): StateFlow<ScanEvent>
fun startCameraScanner(scanKey: String? = null)
}
Singleton Access: Obtain a singleton reference to the ScanEngine instance. This will trigger a background scan using the system's broadcast mechanism.Handle Scan Results: Subscribe to scanEngine.observeScannerResults() for ScanEvent objects containing scan data.
override fun onCreate(savedInstanceState: Bundle?) {
// ...
val scanEngine = ScanEngine.getInstance(context)
// Observing scan result with scanEngine
scanEngine.observeScannerResults().collect { scanEvent ->
// Handle scanEvent result
}
}
Here's example of BarcodeScanner interface:
interface BarcodeScanner {
fun observeScannerResults(): Flow<ScanEvent>
fun scanWithKey(scanKey: String? = null)
}

Initiate Scan: Call scanner.startCameraScanner() to initiate scanning. Pass appropriate scan key if needed, by default its null.Handle Scan Results: Subscribe to the scanEngine.observeScannerResults() flow to receive ScanEvent objects containing scan data.Surfaced from shared tags and platforms — no rankings paid for.
