执行的AsyncTask的doInBackground中的一个线程（） [英] Executing a thread inside AsyncTask's doInBackground()

问题描述

我有几个的AsyncTask 在做网络操作。我最近问的增加，所有这些操作，另一个网络调用，调用远程服务发送的一些统计数据之后。我想这个统计称不耽误主要网络通话，所以我想在创建的线程执行这些而起家的的AsyncTask 的<$内C $ C> doInBackground（）。该线程将在 doInBackground（），可能整个的AsyncTask 结束后，最有可能结束。我想这和它的作品，但如果有副作用，如内存泄漏，或类似的？

I have several AsyncTasks doing network operations. I was recently asked to add, after each of these operations, another network call that invokes a remote service sending some statistics. I'd like this statistics call not to delay 'main' network calls, and so I was thinking of executing them in a thread created and started inside the AsyncTask's doInBackground(). This thread would most probably end after the doInBackground() and possibly the whole AsyncTask has ended. I tried this and it works, but I was wondering if there are side effects, such as memory leaks or similar?

推荐答案

如果你想开始在线程 doInBackground 方法，你可以在 onProgressUpdate（）法

If you want to start thread in doInBackground method, you can start it in onProgressUpdate() method

例如：

protected class MyTask extends AsyncTask<Void,Integer,Void> {

        public static final int START_THREAD = -1;
        @Override
        protected void onProgressUpdate(Integer... values) {
            if(values[0] == START_THREAD){
                startThread();
            }
        }

    @Override
    protected Void doInBackground(Void... params) {
        publishProgress(START_THREAD);
        return null;
    }
}
