使用firebasemlkit访问cloud vision api时关闭javasocket
我正在运行here和Firebase OCR文档示例的一个子集。使用Firebase ML Kit运行云文本识别时，我发现socket已关闭。在带有Android Pie的设备上运行此功能
我尝试过清除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
从资源创建位图并将其传递到runCloudTextRecognition

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();
}
}
});
}

我通过使用位图工厂Options将位图的大小减小到recommended大小来解决我的问题。有关处理大型位图的详细信息，请参见this，也可以使用类似Glide的库。 更新firebase库也有帮助
