Android Google-Покупки API принудительно закрывается при разборе
Я пытаюсь отправить запрос в API Google-Shopping с помощью следующего статического метода, который, как мне кажется, работает:
public static String GET_TITLE(String url) throws JSONException {
InputStream is = null;
String result = "";
JSONObject jArray = null;
// http post
try {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
} catch(Exception e) {
Log.e("log_tag", "Error in http connection "+e.toString());
}
URL, который я передаю, это, кстати, https://www.googleapis.com/shopping/search/v1/public/products/country=US&q=shirts&alt=json & rankBy = релевантность и ключ =AIzaSyDRKgGmJrdG6pV6DIg2m-nmIbXydxvpjww
Затем я пытаюсь проанализировать этот ответ (где, я думаю, проблема возникает) тем же способом:
try {
jArray = new JSONObject(result);
} catch(JSONException e){
Log.e("log_tag", "Error parsing data "+e.toString());
}
JSONObject itemObject = jArray.getJSONObject("items");
JSONObject productObject = itemObject.getJSONObject("product");
String attributeGoogleId = productObject.getString("googleId");
String attributeProviderId = productObject.getString("providerId");
String attributeTitle = productObject.getString("title");*/
String attributePrice = productObject.getString("price");
JSONObject popupObject = productObject.getJSONObject("popup");
return attributeTitle;
}
Это так расстраивает, я знаю, что это должно быть просто, но везде, куда я смотрю, я просто не могу заставить ее работать, я не совсем уверен, в чем ошибка, так как я тестирую ее на своем HTC Desire, потому что мой эмулятор выдает ошибку "неверный параметр командной строки" при запуске, но это, в любом случае, другая проблема, спасибо заранее!

Первый из них выглядит так, как будто есть проблема с URL, должен ли я изменить его и посмотреть, если он имеет значение?

Я нашел ответ на этот вопрос в другом месте, я думаю, что это была лишь незначительная вещь, поскольку она работала после изменения только нескольких вещей, которые мешали ответу быть нулевым при успешной отправке запроса.
In the above the result value is "" since the "Inputstream is" is not being converted to String. to convert it to string use following method and try
public static String convertStreamToString(InputStream is) {
StringBuilder sb = new StringBuilder();
try{
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line).append("\n");
}
is.close();
} catch(OutOfMemoryError om){
//Constants.TEXT_NETWORKERROR = Constants.MSG_ERROR_CONNECTION;
om.printStackTrace();
} catch(Exception ex){
//Constants.TEXT_NETWORKERROR = Constants.MSG_ERROR_CONNECTION;
ex.printStackTrace();
}
return sb.toString();
}//convertStreamToString()
Minor changes in your code to handle NullpointerException
try {
jArray = new JSONObject(result);
JSONObject itemObject = jArray.getJSONObject("items");
JSONObject productObject = itemObject.getJSONObject("product");
String attributeGoogleId = productObject.getString("googleId");
String attributeProviderId = productObject.getString("providerId");
String attributeTitle = productObject.getString("title");*/
String attributePrice = productObject.getString("price");
JSONObject popupObject = productObject.getJSONObject("popup");
return attributeTitle;
} catch(JSONException e){
Log.e("log_tag", "Error parsing data "+e.toString());
return null;
}
