Android 传入Sip呼叫和应答时唤醒设备

当应用程序仍在后台时，窗口标志非常有效，我可以唤醒屏幕并触发

InComingCallActivity

接收SipCalls

我的问题是当用户关闭应用程序时如何唤醒设备，以及当应用程序仍在后台时如何实现同样的唤醒（即当

BroadcastReceiver

唤醒设备收到来电事件并触发相应的意图时）。以下是唤醒设备和打开意图的正确方法。请帮助

    Window window = this.getWindow();
    window.addFlags(LayoutParams.FLAG_DISMISS_KEYGUARD);
    window.addFlags(LayoutParams.FLAG_SHOW_WHEN_LOCKED);
    window.addFlags(LayoutParams.FLAG_TURN_SCREEN_ON);

下面是我的

IncomingCallReceiver

代码，我在这门课上调用

InComingCallActivity

来接听和拒绝来电

public class IncomingCallReceiver extends BroadcastReceiver {
/**
 * Processes the incoming call, answers it, and hands it over to the IncommingCallActivity.
 * 
 * @param context
 *            The context under which the receiver is running.
 * @param intent
 *            The intent being received.
