Barcode Scanner

Android library that provides easy to use and extensible Barcode Scanner views based on Google ML Kit.

Steps to add the library

• Create a Firebase project in the Firebase console, if you don’t already have one
• Add a new Android app into your Firebase project
• Download the config file (google-services.json) from the new added app and move it into the module folder (i.e. app/)
• Add camera permission to your AndroidManifest.xml file

  <uses-permission android:name="android.permission.CAMERA" ></uses-permission>

• Add the following dependency to your build.gradle file

  repositories {
   jcenter()
  }

  ```groovy
  android {
  …
  // BarcodeScanner requires Java 8.
  compileOptions {
  sourceCompatibility JavaVersion.VERSION_1_8
  targetCompatibility JavaVersion.VERSION_1_8
  }
  }

dependencies {
implementation ‘com.neyogiry.scanner0.1.0’
}

## Simple usage
A very basic activity would look like this:
```kotlin
class ScannerActivity : AppCompatActivity(), BarcodeScannerView.BarcodeResult  {
    private var preview: CameraSourcePreview? = null
    private var graphicOverlay: GraphicOverlay? = null
    private var barcodeScanner: BarcodeScannerView? = null
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_scanner)
        preview = findViewById(R.id.camera_preview)
        graphicOverlay = findViewById<GraphicOverlay>(R.id.camera_preview_graphic_overlay)
        barcodeScanner = BarcodeScannerView(this)
        barcodeScanner?.onCreate(preview!!, graphicOverlay!!)
        barcodeScanner?.setBarcodeResult(this)
    }
    override fun onResume() {
        super.onResume()
        barcodeScanner?.onResume()
    }
    override fun onPause() {
        super.onPause()
        barcodeScanner?.onPause()
    }
    override fun onDestroy() {
        super.onDestroy()
        barcodeScanner?.onDestroy()
    }
    override fun onBarcodeResult(value: String) {
        Log.i(TAG, "The value is $value)
    }
}
