恢复后 Android Runnable 运行速度更快 [英] Android Runnable runs faster after Resume

问题描述

我有一个 runnable，它每 1 秒输出一个变量的值.runnable 在我启动 mainActivity 时启动，并在后台运行整个应用程序.

I have a runnable that outputs a the value of a variable every 1 second. The runnable starts when I start the mainActivity and runs throughout the app in the background.

当我关闭应用程序(隐藏状态)并再次启动应用程序时，logcat 开始输出更快.每次我这样做时它都会变得更快.为什么?

When I close the app (hidden state) and start the app again, the logcat starts outputting faster. It goes faster everytime I do this. Why ?

@Override
public void onStart()
{
    mHandler.postDelayed(myRunnable, 1000);
    super.onStart();
}

 public Runnable myRunnable = new Runnable()
 {
    @Override
    public void run()
    { 
       count ++;
       android.util.Log.w("     SYNC     ", "COUNT:"+count);
       mHandler.postDelayed(myRunnable, 1000);
    }
};
