tensorflow: Object Detection Android App Crash

I am trying to convert my custom MobileNet Single Shot Detector (v2) TF 1.x to tflite using Roboflow tutorial colab. After Conversion I deploy it on Tensorflow android app demo . When I run the app it always crashes after lunch immediately showing the following error: ‘’’ E/AndroidRuntime: FATAL EXCEPTION: main Process: org.tensorflow.lite.examples.detection, PID: 10743 java.lang.AssertionError: Error occurred when initializing ObjectDetector: Input tensor has type kTfLiteFloat32: it requires specifying NormalizationOptions metadata to preprocess input images. at
