无法从android中的feed url（JSON格式）检索整个数据

Question

DATA包括TELUGU WORDS ..所以有人可以帮我这个吗？

charArray大小超过我的需要..

HttpURLConnection connection = (HttpURLConnection) blogFeedUrl.openConnection();
connection.connect();
InputStream inputStream = connection.getInputStream();
Reader reader = new InputStreamReader(inputStream);

int contentLength = connection.getContentLength();
char [] charArray = new char[400000];
reader.read(charArray);
String responseData = new String(charArray);
Log.v(TAG, responseData);
