java - 使用 firebase-mlkit 访问云视觉 api 时套接字关闭

Question

我正在运行给出的示例的子集 here和 Firebase OCR 文档。我在使用 Firebase ML Kit 运行云文本识别时收到套接字已关闭的消息。在装有 Android Pie 的设备上运行此程序。

我尝试清除 Google Play 服务缓存、重新启动设备(使其工作 1 次)、创建网络安全配置以允许从 here 发送/接收 HTTP 请求

从 Asset 创建位图并将其传递到 runCloudTextRecognition

Android list

<uses-permission android:name="android.permission.INTERNET" />
<application>
<meta-data
            android:name="com.google.firebase.ml.vision.DEPENDENCIES"
            android:value="ocr" />

runCloudTextRecognition 和 getBitmapFromAsset

public static Bitmap getBitmapFromAsset(Context context, String filePath) {
        AssetManager assetManager = context.getAssets();
        InputStream istr;
        Bitmap bitmap = null;
        try {
            istr = assetManager.open(filePath);
            bitmap = BitmapFactory.decodeStream(istr);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return bitmap;
    }

private void runCloudTextRecognition(Bitmap mSelectedImage) {
        //mCloudButton.setEnabled(false);
        FirebaseVisionImage image = FirebaseVisionImage.fromBitmap(mSelectedImage);
        final FirebaseVisionTextRecognizer recognizer = FirebaseVision.getInstance()
                .getCloudTextRecognizer();
        recognizer.processImage(image)

                .addOnSuccessListener(
                        new OnSuccessListener<FirebaseVisionText>() {
                            @Override
                            public void onSuccess(FirebaseVisionText texts) {
                                //mCloudButton.setEnabled(true);
                                Log.e("CloudOCR_Success",texts.getText());
                            }
                        })
                .addOnFailureListener(
                        new OnFailureListener() {
                            @Override
                            public void onFailure(@NonNull Exception e) {
                                // Task failed with an exception
                                //mCloudButton.setEnabled(true);
                                e.printStackTrace();
                                try {
                                    recognizer.close();
                                } catch (IOException e1) {
                                    e1.printStackTrace();
                                }
                            }
                        });
    }

Answer 1

我通过将位图大小减小到 recommended 解决了我的问题使用 BitmapFactory 的大小 Options 。有关处理大位图的更多信息，请参阅 this或者您可以使用类似 Glide 的库。 更新 firebase 库也有帮助。
