{% endhint %}

## Step 2 : Open Liveness camera screen

* Customize camera screen **(Optional)**<br>

  ```
  // To customize your screen theme and feed back messages
  LivenessCustomization livenessCustomization = new LivenessCustomization();

  livenessCustomization.backGroundColor = getResources().getColor(R.color.livenessBackground);
  livenessCustomization.closeIconColor = getResources().getColor(R.color.livenessCloseIcon);
  livenessCustomization.feedbackBackGroundColor = Color.TRANSPARENT;
  livenessCustomization.feedbackTextColor = Color.BLACK;
  livenessCustomization.feedbackTextSize = 18;
  livenessCustomization.feedBackframeMessage = "Frame Your Face";
  livenessCustomization.feedBackAwayMessage = "Move Phone Away";
  livenessCustomization.feedBackOpenEyesMessage = "Keep Your Eyes Open";
  livenessCustomization.feedBackCloserMessage = "Move Phone Closer";
  livenessCustomization.feedBackCenterMessage = "Move Phone Center";
  livenessCustomization.feedBackMultipleFaceMessage = "Multiple Face Detected";
  livenessCustomization.feedBackHeadStraightMessage = "Keep Your Head Straight";
  livenessCustomization.feedBackBlurFaceMessage = "Blur Detected Over Face";
  livenessCustomization.feedBackGlareFaceMessage = "Glare Detected";
  livenessCustomization.feedBackLowLightMessage = "Low light detected";
  livenessCustomization.feedbackDialogMessage = "Loading...";
  livenessCustomization.feedBackProcessingMessage = "Processing...";
  livenessCustomization.showlogo = 0; // Set 0 to hide logo from selfie camera screen
  livenessCustomization.logoIcon = R.drawable.your_logo; // To set your custom logo
      
  // LivenessCustomization.CAMERA_FACING_FRONT to set selfie camera       
  // LivenessCustomization.CAMERA_FACING_BACK to set rear camera
  livenessCustomization.facing = LivenessCustomization.CAMERA_FACING_FRONT;
      
  // 0 for full dark face and 100 for full bright face or set it -1 to remove low light filter
  livenessCustomization.setLowLightTolerence(-1/*lowLightTolerence*/);

  // 0 for clean face and 100 for Blurry face or set it -1 to remove blur filter
  livenessCustomization.setBlurPercentage(80/*blurPercentage*/); // To allow blur on face
                                                  
  // Set min and max percentage for glare or set it -1 to remove glare filter
  livenessCustomization.setGlarePercentage(6/*glareMinPercentage*/, 99/*glareMaxPercentage*/);
  ```

* Open Camera screen using android **Intent.**<br>

  ```
  Intent intent = SelfieCameraActivity.getCustomIntent(this, livenessCustomization, "your_url");
  startActivityForResult(intent, ACCURA_LIVENESS_CAMERA);
  ```

{% hint style="info" %} <mark style="color:blue;">**Note:**</mark> If you want to use default camera screen then create intent with null object.\
Intent intent = SelfieCameraActivity.getCustomIntent(this, null, "your\_url");&#x20;
{% endhint %}

* Receive Capure Image and liveness score<br>

  ```
  @Override
  protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
      super.onActivityResult(requestCode, resultCode, data);
      if (resultCode == RESULT_OK) {
          if (requestCode == ACCURA_LIVENESS_CAMERA && data != null) {
              AccuraVerificationResult result = data.getParcelableExtra("Accura.liveness");
              if (result == null) {
                  return;
              }
              if (result.getStatus().equals("1")) {
                  // get face image
                  Bitmap bitmap = result.getFaceBiometrics();
                  double livenessScore = result.getLivenessResult().getLivenessScore() * 100.0;
                  Toast.makeText(this, "Liveness Score : " + livenessScore, Toast.LENGTH_SHORT).show();
              } else {
                  Toast.makeText(this, result.getStatus() + " " + result.getErrorMessage(), Toast.LENGTH_SHORT).show();
              }
          }
      }
  }
  ```
