Android 中service 详解_activitymanager: unable to start service intent {

上一次对于broadcast 的机制进行了详细的解析，见博文 android 中的 Broadcast 机制详解 ，本篇对于四大组件中的另一个成员—— service 进行解读。

在开发中我们会碰到下面几种情况：

1、java.lang.IllegalStateException: Not allowed to start service Intent

2、Bringing down service while still waiting for start foreground

4、java.lang.SecurityException: Unable to start service

5、java.lang.SecurityException: Not allowed to start service

带着这么多的问题，有必要对于Android 中的service 进行剖析。将 AMS 中service 机制解析分以下几部分：

Android service 启动篇：

        Android service 启动篇之 startService

        Android service 启动篇之 bindService

        Android service 启动篇之 startForegroundService

Android service 停止篇：
