我正在开发Android应用程序，该应用程序使用java中的谷歌视觉api和wolfram-alpha-api来显示数学方程的求解，但我认为错误是云视觉api请求失败。查看日志以了解详细信息。如何修复此错误。我的毕业设计需要你的帮助。请帮帮我。

// Do the real work in an async task, because we need to use the network anyway
new AsyncTask<Object, Void, String>() {

Log.e("Line 255:", "This line has been executed");
HttpTransport httpTransport = AndroidHttp.newCompatibleTransport();
JsonFactory jsonFactory = GsonFactory.getDefaultInstance();
VisionRequestInitializer requestInitializer =
new VisionRequestInitializer(CLOUD_VISION_API_KEY) {
/**

visionRequest.getRequestHeaders().set(ANDROID_PACKAGE_HEADER, packageName);

add(annotateImageRequest);
}});
Vision.Images.Annotate annotateRequest =
vision.images().annotate(batchAnnotateImagesRequest);
// Due to a bug: requests to Vision API containing large images fail when GZipped.
annotateRequest.setDisableGZipContent(true);
BatchAnnotateImagesResponse response = annotateRequest.execute();
return convertResponseToString(response);

} catch (IOException e) {

我好像错过了什么。我接受logcat中的这个错误。

我也有同样的问题，我认为你必须启用计费帐户。
