错误消息：字段要求API级别11（当前最小值为8）：android.os.AsyncTask＃THREAD_POOL_EXECUTOR

Question

@Override
                protected void onPostExecute(Void result) {
                    buttonDOpen.setOnClickListener(new View.OnClickListener() {
                        @TargetApi(Build.VERSION_CODES.HONEYCOMB)
                        public void onClick(View v) {
                            final Sender messageSender = new Sender(); // Initialize chat sender AsyncTask.
                            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
                                messageSender.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
                            } else {
                                messageSender.execute();
                            }
                        }
                    });

I wanted to send messages from phone to computer I found myself ready example, but when I threw it in the project it gives red line error. Does anyone know a solution to fix errors?

在此方法上添加@TargetApi(Build.VERSION_CODES.HONEYCOMB)作为注释，以表明您（AFAYK）已正确实现了API级别11。
