Tflite model not detecting any objects

I have trained a object detection model using tflite_model_maker in tensorflow’s google colab!
When I take prediction in the colab I get bounding boxes and the model detects but when i use it in my android app it does not detect anything.
I am using ml kit in android studio so when I start the camera activity to start prediction it does not enter onSuccessListener it gives me output from onFailureListener.
