下面我已经发布了代码并指出了错误行：
creategroup.java:创建组：
public class CreateGroup extends AppCompatActivity {
........
........
@Override
protected String doInBackground(String... params) {
try {
.......
ServerCallee.execute(Constants.SERVER_CALL_newGroup, map); --->213th line
} catch (JSONException e) {
e.printStackTrace();
return "1";
}
服务器callee.java：
public static void execute(final Constants _service, HashMap<String, String> params){
........
........
RestClient.get(null, rqm, new JsonHttpResponseHandler(){ --->77th line
........
@Override
public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
System.out.println("onFailure - String: " + _service.toString());
Log.e("fail 1", "Test");
}
.......(On Success response handler)
restclient.java：
public class RestClient {
private static AsyncHttpClient client = new AsyncHttpClient();
public static void get( String url, RequestParams params, final JsonHttpResponseHandler responseHandler) {
client.get(getAbsoluteUrl(url), params, responseHandler); -->29th line
}
public static void post(final String url, final RequestParams params, final JsonHttpResponseHandler responseHandler) {
client.get(getAbsoluteUrl(url), params, responseHandler);
}
}
最佳答案：
AsyncTaskSyncHttpClient
