谷歌文本识别错误 Android Studio

Question

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

I have faced a similar problem before.

These are not actual errors. They are just warnings and messages. You can ignore them. What I guess is, you are putting true in the boolean variable success on onSuccess and false on onFailure and performing further actions based on its value.

Just directly call further methods from onSuccess after string = text.getText();
