Setup Accura Finger
To initialize sdk on app start:
FingerEngine fingerEngine = new FingerEngine();
FingerEngine.SDKModel sdkModel = fingerEngine.initEngine(your activity context);
if (sdkModel.i > 0) { // if license is valid
if (sdkModel.isFingerEnable) // RecogType.FINGER_PRINT
}Set CameraView
Must have to extend com.accura.finger.print.sdk.motiondetection.SensorsActivity to your activity.
- Make sure your activity orientation locked from Manifest. Because auto rotate not support.
private CameraView cameraView;
@Override
public void onCreate(Bundle savedInstanceState) {

// Recog type selection base on your license data

// initialized camera
initCamera();

.setView(linearLayout) // To add camera view
.setCameraFacing(0) // To set selfie(1) or rear(0) camera.
.setFingerCallback(this) // To get scanning status
.setStatusBarHeight(statusBarHeight) // To remove Height from Camera View if status bar visible
// Optional setup
// .setEnableMediaPlayer(false) // false to disable default sound and true to enable sound and default it is true
// .setCustomMediaPlayer(MediaPlayer.create(this, /*custom sound file*/)) // To add your custom sound and Must have to enable media player
