在postDelayed的延迟之后，Runnable很长时间了 [英] Runnable is excecuted long time after postDelayed's delay

问题描述

在某些时候，我希望我的Android背景服务在2秒后执行某些操作。所以 - 我准备了一个指定的处理程序：

At some point I want my android background Service to execute something after 2 seconds. So - I had prepared a designated Handler:

private Handler handler;
...
HandlerThread thread = new HandlerThread("LNT");
thread.start();
handler = new Handler(thread.getLooper());

然后我调用< br $> b $ b

and then I call

handler.postDelayed (new Runnable(){
    public void run(){
        doSomething();
}, (long)(2000));

有时候soSomething（）在2秒后被调用，但很多时候需要15秒!!



我做错了什么？

在特定时间段之后还有另一种方法可以运行吗？

sometimes soSomething() is being called after 2 seconds, but many times it take up to 15 seconds !!

What am I doing wrong?
Is there another way to run something after a specific period of time?
