public String makeServiceCall(String url) {
    try {
      // http client
      DefaultHttpClient httpClient = new DefaultHttpClient();
      HttpEntity httpEntity = null;
      HttpResponse httpResponse = null;

      HttpGet httpGet = new HttpGet(url);
      httpResponse = httpClient.execute(httpGet);
      httpEntity = httpResponse.getEntity();

Answer 1

我从@blackTigher提供的链接中得到了答案......

问题是因为主线上的网络......

所以在连接到httpclient之前添加了这段代码

 StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
 StrictMode.setThreadPolicy(policy);

它对我有用......

有关详细信息，请访问NetworkOnMainThreadException
