JSONObject的大型JSON字符串不起作用

Question

protected class saveBtnClickHandler implements OnClickListener{
    @Override
    public void onClick(View v) {
           String jsonRest = loadJsonDataFromURL("http://thirddhaba.appspot.com/api/v1/circle/condensed/data/?circle_id=1");
    try {
            JSONObject jsonObj = new JSONObject(jsonRest);  

        } catch (JSONException e) {
              android.util.Log.e("JSON Parser", "Error parsing data " + e.toString());
        }
    }
}

protected String loadJsonDataFromURL(String url){
     String jsonStr = null;
    try {
         HttpClient httpclient = new DefaultHttpClient();
            HttpResponse response = httpclient.execute(new HttpGet(url));
            StatusLine statusLine = response.getStatusLine();
            if(statusLine.getStatusCode() == HttpStatus.SC_OK){
                ByteArrayOutputStream out = new ByteArrayOutputStream();
                response.getEntity().writeTo(out);
                out.close();
                 jsonStr = out.toString();

            } else{
                //Closes the connection.
                response.getEntity().getContent().close();
                throw new IOException(statusLine.getReasonPhrase());
            }
    } catch (Exception e) {
        // TODO: handle exception
    }
    return jsonStr;
}

上面的代码工作正常.但是此JSON(链接)URL字符串未转换为JSON对象.我认为这是大字符串也添加错误屏幕截图.

您的测试数据基于[]包含在数组中.您需要将其解析为json数组而不是json对象.

JSONArray jsonArr = new JSONArray(jsonRest);
