Android 短信广播接收相关问题
本人是Android新手，最近做了一个关于监听手机短信功能的应用，我在网上看资料了解到广播分为有序广播和无序广播，有序广播；无序广播又称普通广播，其中的利弊我也一时没搞清楚，我用的是有序广播实现的，具体思路如下
1、定义一个接收短信的广播
2、当系统接收到短信时，拦截短信，获取短信内容
3、将指定的短信内容转发到服务器
下面是我的实现方法
1、添加一个短消息接收类

好了，配置好之后就可以编译你的项目了，在手机上安装测试可以正常运行，但是有一些问题，就是在某些手机上短信广播接收不到，例如小米和以前的某些牌子的老款智能手机，我在网上查了查，有认说是广播优先级问题，同是短信应用软件，先安装的优先级高，还有一种情况，是软件本身的优先级高，但是都没有提出具体的解决方案，还有一个原因就是系统本身的安全机制，由于某些设置导致短信应用软件不能正常使用，例如小米手机，在短信设置里面好像有一项和短信接收有关的设置，调整之后就可以接收了，但其他手机还没有解决，如果有哪个大牛有好的解决方案，给小弟指点迷津，感激不尽。
