说说Android的广播(4) - 前台队列为什么比后台队列快？

说说Android的广播(4) - 前台队列为什么比后台队列快？前台队列为什么比后台队列快讨论超时的细节之前，我们先讲讲对应用开发有帮助的，为什么前台队列比后台队列要快？应用开发的同学在给系统团队提意见的时候讲，说以前我们都是靠通过将广播消息设成前台广播的方式来做workaround来解决一些广...

说说Android的广播(2) - 并发队列和串行队列

并发队列和串行队列前面我们讲了，消息分为普通消息和有序消息两大类。普通消息是可以并发的，由于是并发的，这些广播的处理者之间互相是不依赖的。另外，并发队列和串行队列都各维护了一条后台广播队列和前台广播队列。如果这个消息足够重要，想走快速通道的话，可以选择使用前台广播队列。对于并发队列，如果是进程...
