Google Text Recognition Error Android Studio

I am developing an app in which I am implementing google text recognition. This is the link that I am following : https://developers.google.com/ml-kit/vision/text-recognition/android

I have done everything described there but still I am getting error.

This is what I have in my gradle file:

implementation 'com.google.android.gms:play-services-mlkit-text-recognition:16.1.0'

I have these lines too in my manifest file:

<uses-permission android:name="android.permission.INTERNET"/>

<meta-data
    android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version"/>
<meta-data
    android:name="com.google.mlkit.vision.DEPENDENCIES"
    android:value="ocr" />

I am performing a click on a button OCR and then I am calling below lines of code:

InputImage inputImage = InputImage.fromBitmap(bitmap, 0);
            TextRecognition.getClient().process(inputImage).addOnSuccessListener(new OnSuccessListener<Text>() {
                @Override
                public void onSuccess(Text text) {
                    string = text.getText();
                    success = true;
                }
            }).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    e.printStackTrace();
                    success = false;
                }
            });

Error is thrown as soon as I Click on OCR button. Following is the stack trace:

How can I rectify this error. Thank you
