emm,I'm Sorry to say that the result I just said before is not right. By using the native method setScreenState(), I make my device's screen off.The code is:
int x=Power.setScreenState(false);//make the screen off System.out.println(x);//0 will be print out Thread.sleep(3000); x=Power.setScreenState(true);//make the screen on System.out.println(x);//0 will be print out I tried this code on emulator, it works too.
