Usage

Setup

val camera = FaceAuthenticationCamera
val configuration =
    FaceAuthConfigurationBuilder.setUserLicense(stringResource(id = "LicenseKey"))

//Inside a composable function just do the following
@Composable
fun MyComposable() {
    camera.FaceAuthCamera(
        configurationBuilder = configuration,
        firstImage = Bitmap.createBitmap(1, 1, Bitmap.Config.ARGB_8888),
        secondImage = Bitmap.createBitmap(1, 1, Bitmap.Config.ARGB_8888),
        onMatchResultsFirstImage = { FaceMatchResults ->
            
        },
        onMatchResultsSecondImage = { FaceMatchResults ->
            
        },
    )
}

Using Fragments in Kotlin or Java

In your activity_main.xml file add the following:

<androidx.fragment.app.FragmentContainerView android:layout_width="match_parent"
    android:layout_height="match_parent" android:id="@+id/main_container" />

//Create a FaceDetectionFragment and call the Face Camera
class FaceDetectionFragment : Fragment() {
    @RequiresApi(Build.VERSION_CODES.O)
    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View {
        val view = ComposeView(requireContext())
        view.apply {
            setContent {
                Column(
                    modifier = Modifier.fillMaxSize(),
                ) {
                    MyComposable()
                }
            }
        }
        return view
    }

    @Composable
    fun MyComposable() {
        val camera = FaceAuthenticationCamera
        val configuration =
            FaceAuthConfigurationBuilder.setUserLicense(stringResource(id = "LicenseKey"))

        camera.FaceAuthCamera(
            configurationBuilder = configuration,
            firstImage = Bitmap.createBitmap(1, 1, Bitmap.Config.ARGB_8888),
            secondImage = Bitmap.createBitmap(1, 1, Bitmap.Config.ARGB_8888),
            onMatchResultsFirstImage = { FaceMatchResults ->

            },
            onMatchResultsSecondImage = { FaceMatchResults ->

            },
        )
    }
}

On your activity then call the FaceDetectionFragment

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        supportFragmentManager.beginTransaction()
            .replace(R.id.main_container, FaceDetectionFragment()).commit()
    }
}
