都是中国人，就不用什么鸟英语了，直接汉字。 Power 类在应用的时候，我不知道是否有权限的问题。也许正如上面Yuri所说，也许在Activity下使用有可能有权限限制。 因为我写的程序是没有activity的，而且拥有最高的权限，貌似部分系统进程都没他高，所以才能实现。 我是通过把代码放到源码中重新编译得到如此高权限的程序的。 On 7月22日, 下午4时26分, Stephen Le yangle...@gmail.com wrote: As you say, I tried to import this class into my Activity..But It is doesn't work..Do you have any demo project to give me ?

[android-developers] Re: How to power off the screen?
o...这样！我试过的了，只要用到系统进程，都要求有google的数字签名。所以关屏幕是不好使的！模拟器上是可以关的，一部署到机器上就要求和你使用的google程序进程签名一样才可以了。。 你写的程序是不是直接在他的package里面自己写了一个java类调用这个Power类？那是怎样实现在Activity里面调用你这个程序的呢？因为这个类，没有在Android.jar里面？ On Wed, Jul 22, 2009 at 5:34 PM, Sansiro wangjiangfeng0...@gmail.comwrote: 都是中国人，就不用什么鸟英语了，直接汉字。 Power 类在应用的时候，我不知道是否有权限的问题。也许正如上面Yuri所说，也许在Activity下使用有可能有权限限制。 因为我写的程序是没有activity的，而且拥有最高的权限，貌似部分系统进程都没他高，所以才能实现。 我是通过把代码放到源码中重新编译得到如此高权限的程序的。 On 7月22日, 下午4时26分, Stephen Le yangle...@gmail.com wrote: As you say, I tried to import this class into my Activity..But It is doesn't work..Do you have any demo project to give me ?

[android-developers] Re: How to power off the screen?
In Android Souccr code, I find a Power class packaged in android.os. This class is not provided in SDK,But this is really a public class. This class has five native method: public static native void shutdown() public static native void reboot(String reason) throws IOException public static native int setLastUserActivityTimeOut(long ms) public static native int setScreenState(boolean on) public static native int setLightBrightness(int mask,int brightness) You can try the fourth method.
