App发送keyevent到framework

参考：https://www.cnblogs.com/TerryBlog/archive/2012/06/07/2539866.html

一，Andmenifest.xml中添加system权限

android:sharedUserId="android.uid.system"

二，sendKeyDownUpSync发送keyevent

    public void sendFrameworkKeyEvent(int keyEvent) {
        final int keyCode = keyEvent;
        new Thread(new Runnable() {
            public void run() {
                try {
                    SkyALinkLog.d(TAG, "SendFrameworkKeyEvent begin = " + keyCode);
                    new Instrumentation().sendKeyDownUpSync(keyCode);
                    SkyALinkLog.d(TAG, "SendFrameworkKeyEvent end = " + keyCode);
                } catch (Exception exception) {
                    SkyALinkLog.d(TAG, "SendFrameworkKeyEvent = " + exception.toString());
                }
            }
        }).start();
    }
