如何在Android中删除致命异常：AsyncTask

如何在Android中删除致命异常：AsyncTask

原因是，你只能消耗

Content

的

Entity

一次。

您在这里做了两次（可能不知道）

Reader reader = new InputStreamReader(response.getEntity().getContent());

和这里

response.getEntity().writeTo(out);

我知道这听起来有些怪异，但实际上writeTo（）函数将从实体获取内容并将其写入

OutputStream

。您可以在此处的文档中看到它

您可以使用的另一种解决方法是将其转换为字符串，然后让GSON处理

@Overrideprotected String doInBackground(String... uri) {    HttpClient httpclient = new DefaultHttpClient();    HttpResponse response;    String responseString = null;    try {        response = httpclient.execute(new HttpGet(uri[0]));        StatusLine statusLine = response.getStatusLine();        if(statusLine.getStatusCode() == HttpStatus.SC_OK){ responseString = EntityUtils.toString(response.getEntity()); // content will be consume only once Gson gson = new Gson(); Holder response1 = gson.fromJson(responseString, Holder.class);        } else{ //Closes the connection. response.getEntity().getContent().close(); throw new IOException(statusLine.getReasonPhrase());        }    } catch (ClientProtocolException e) {        //TODO Handle problems..        progressDialog.hide();    } catch (IOException e) {        //TODO Handle problems..        progressDialog.hide();    }    return responseString;}

希望我的回答能对您有所帮助！
