大家都知道组件的执行任务的时间过长可能会导致ANR，但具体是多久呢？源码里面都定义了宏，我们把它们找出来，做了记录

Service Timeout

文件：ActiveServices.java

    // How long we wait for a service to finish executing.    static final int SERVICE_TIMEOUT = 20*1000; // 前台    // How long we wait for a service to finish executing.    static final int SERVICE_BACKGROUND_TIMEOUT = SERVICE_TIMEOUT * 10; // 后台

broadcast Timeout

文件：ActivityManagerService.java

    // How long we allow a receiver to run before giving up on it.    static final int BROADCAST_FG_TIMEOUT = 10*1000;  // 前台    static final int BROADCAST_BG_TIMEOUT = 60*1000;  // 后台

InputDispatching Timeout

文件：ActivityManagerService.java

    // How long we wait until we timeout on key dispatching.    static final int KEY_DISPATCHING_TIMEOUT = 5*1000;

ContentProvider Timeout

文件：

    // How long we wait for an attached process to publish its content providers    // before we decide it must be hung.    static final int CONTENT_PROVIDER_PUBLISH_TIMEOUT = 10*1000;

这个时间的统计区间是在System_Server进程调用startProcessLocked之后会调用AMS.attachApplicationLocked，以这为起点，一直到provider进程installProvider以及publishContentProviders，调用到AMS.publishContentProviders为止。超过了这个时间就会系统就会杀掉Provider进程
