これは私のコードです:

public class AndroidJSONActivity extends Activity {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Toast.makeText(getApplicationContext(),"sdasdsadsa231",2100).show();
        String readTwitterFeed = readTwitterFeed();

        try {
            JSONArray jsonArray = new JSONArray(readTwitterFeed);
            Log.i(AndroidJSONActivity.class.getName(),
                "Number of entries " + jsonArray.length());
            for (int i = 0; i < jsonArray.length(); i++) {
              JSONObject jsonObject = jsonArray.getJSONObject(i);
              Log.i(AndroidJSONActivity.class.getName(), jsonObject.getString("text"));
            }
          } catch (Exception e) {
            e.printStackTrace();
          }




    }

    private String readTwitterFeed() {
        Toast.makeText(getApplicationContext(),"sdasdsadsa231",3100).show();
         StringBuilder builder = new StringBuilder();
            HttpClient client = new DefaultHttpClient();
            HttpGet httpGet = new HttpGet("....../video.php");

            try {

              HttpResponse response = client.execute(httpGet);

              StatusLine statusLine = response.getStatusLine();
              int statusCode = statusLine.getStatusCode();

              if (statusCode == 200) {
                Toast.makeText(getApplicationContext(),"sdasdsadsa",4000).show();
                HttpEntity entity = response.getEntity();
                InputStream content = entity.getContent();
                BufferedReader reader = new BufferedReader(new InputStreamReader(content));
                String line;
                while ((line = reader.readLine()) != null) {
                  builder.append(line);
                }
              } else {
                Log.e(AndroidJSONActivity.class.toString(), "Failed to download file");
              }
            } catch (ClientProtocolException e) {
              e.printStackTrace();
              Toast.makeText(getApplicationContext(),"sdasdsa323424326a",4000).show();
            } catch (IOException e) {
                Toast.makeText(getApplicationContext(),"sdasdsa323424326a",4000).show();
              e.printStackTrace();
            }
            return builder.toString();
    }
}

私のファイル...

{"view":"topstory","content":[{"story_id":"128","title":"testuser2","story_description":"

testuser2<\/p>","story_video_file":"","story_video_link":"","images":..

ファイルを観察してください。データの間に行スペースがあります (後)

story_description":" ),

そのスペースに問題はありますか..これに対する解決策を提案してください....
