Android系统默认关闭第三方通知

一开始是在service里面写的代码，在service里面采用广播来监听应用安装的广播。

    @Override

        super.onDestroy();
        if (isRegister) {
            unregisterReceiver(mBatteryReceiver);
            isRegister = false;
        }
		unregisterReceiver(mInstallReceiver);
    }
}

遇到的问题这样子的，每次开机service里面都是可以获取应用的uid的，但是监听那应用安装的广播却获取不到刚安装应用的uid，折腾了一下午，没招，最后只能在PMS里面实现相关逻辑。

在PMS里面当应用安装好后就关闭掉此应用的通知。
