Question

任何人都可以帮我剖析这个错误日志吗？抛出它的类几乎与在同一程序中正常工作的另一个类相同。唯一的区别是我添加了一个List并将参数传递给json请求的URL

 protected String doInBackground(String... args) {
            // Building Parameters
            List<NameValuePair> params = new ArrayList<NameValuePair>();
            // getting JSON string from URL
            //params.add(new BasicNameValuePair("category","cat"));

第74行：JSONObject json = jParser.makeHttpRequest（url_get_channels，“GET”，params）;

            // Check your log cat for JSON reponse
            Log.d("All Products: ", json.toString());

Answer 1

“android.view.WindowLeaked”异常怎么样？这意味着您正试图通过“已关闭”活动显示对话框。
