new CountDownTimer(1320000, 200) {

    public void onTick(long millisUntilFinished) {
        // I update a progress bar here.

推荐答案

WakeLock通常不会导致重新启动的问题。有可能是你的代码的一些其他问题。WakeLock猪电池严重，如果使用后，不会发布

WakeLock doesn't usually cause Reboot problems. There may be some other issues in your coding.WakeLock hogs battery heavily, if not released after usage.

WakeLock是保持在屏幕的低效的方式。而是使用窗口管理器做的神奇。下面的一行就足够了WakeLock。 另外这款code是效率比wakeLock。

WakeLock is an Inefficient way of keeping the screen on. Instead use the WindowManager to do the magic. The following one line will suffice the WakeLock. Also this code is efficient than the wakeLock.

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

您不必RELASE的WakeLock手动。这code将使Android系统来处理自动上锁。当应用程序在前台运行，然后WakeLock保持和其他Android系统会自动解锁。

You need not relase the WakeLock Manually. This code will allow the Android System to handle the Lock Automatically. When your application is in the Foreground then WakeLock is held and else android System releases the Lock automatically.
