InnerReceiver 用于和系统进程通信
ArrayList
应用进程的接收者在系统进程中的代理
ReceiverList
ActivityManagerService ownerIIntentReceiver receiverProcessRecord app // 注册者进程
BroadcastReceiver
- PendingResult mPendingResult
注册者进程
方法参数
前台/后台消息队列
动态接收者在系统进程中的实体
IIntentReceiver.Stub
+ void performReceive(... ... ...)
用于封装广播接收者的IntentFilter
应用定义的动态接收者
BroadcastQueue
+ ActivityManagerService mService+ ArrayList mParallelBroadcasts+ ArrayList mOrderedBroadcasts+ BroadcastRecord mPendingBroadcast+ BroadcastHandler mHandler... ... ... ...
+ void enqueueParallelBroadcastLocked(BroadcastRecord r)+ void scheduleBroadcastsLocked()+ void processNextBroadcast(boolean fromMsg)... ... ... ...
四大组件，进程的状态管理者
每个进程都有一个实例
ReceiverDispatcher.InnerReceiver
+ WeakReference<LoadedApk.ReceiverDispatcher> mDispatcher+ LoadedApk.ReceiverDispatcher mStrongRef // 为 false；
BroadcastFilter
ReceiverList receiverListString packageNameString requiredPermissionint owningUidint owningUserId
ProcessRecord
- ArraySet receivers
ActivityManagerService
+ Intent registerReceiver(... ... ...)+ BroadcastQueue broadcastQueueForIntent(Intent intent)
Runnable
相互关联
abstract
对于有序广播来说会通过 sendFinished 方法通知 AMS 广播的接收状态
