Google文字识别错误Android Studio

问题描述

我正在开发一个应用程序，其中正在实现Google文本识别。 这是我关注的链接： https://developers.google.com/ml-kit/vision/text-recognition/android

我已经完成了此处描述的所有操作，但仍然出现错误。

这是我的gradle文件中的内容：

<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" />

清单文件中也有这些行：

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;
                }
            });

我正在单击按钮 OCR ，然后调用下面的代码行：

我单击 OCR 按钮后立即引发错误。 以下是堆栈跟踪：

如何纠正此错误。 谢谢

解决方法

我以前也遇到过类似的问题。

这些不是实际错误。它们只是警告和消息。您可以忽略它们。 我猜是，您在onSuccess的布尔变量 成功 中为true，在onFailure为false，并根据其值执行进一步的操作。

只需在string = text.getText（）;之后直接从onSuccess调用其他方法即可
