Android(安卓)BroadcastReceiver 学习笔记

Sender:sender是否具有某种Permission与所处的Package申明有关，与sendBroadcast方法是相互独立的。sendBroadcast可以要求接受方需要具备什么Permission。

Receiver: receive是否具有某种Permission与所处的Package申明有关, 与registerReceiver方法是相互独立的。registerReicerver可以要求发送方需要具备什么Permission。

	Package	In Permission	In Permission	No permission	No permission
Package	Receiver\sendBroadcast	Send not require P	Send require P	Send not require P	Send require P
In Permission	Declared require P	onReceive	onReceive	Permission Denial: broadcasting Intent	Permission Denial: broadcasting Intent
In Permission	Declared not require P	onReceive	onReceive	onReceive	onReceive
In Permission	Dynamic require P	onReceive	onReceive	Permission Denial: broadcasting Intent	Permission Denial: broadcasting Intent
In Permission	Dynamic not require P	onReceive	onReceive	onReceive	onReceive
No Permission	Declared require P	onReceive	Permission Denial: receiving Intent	Permission Denial: broadcasting Intent	Permission Denial: broadcasting Intent Permission Denial: receiving Intent
No Permission	Declared not require P	onReceive	Permission Denial: receiving Intent	onReceive	Permission Denial: receiving Intent
No Permission	Dynamic require P	onReceive	Permission Denial: receiving Intent	Permission Denial: broadcasting Intent	Permission Denial: broadcasting Intent Permission Denial: receiving Intent
No Permission	Dynamic not require P	onReceive	Permission Denial: receiving Intent	onReceive	Permission Denial: receiving Intent

Receiver是Declared或Dynamic的对结果并无影响。上述表格可以简化为

	Package	In Permission	In Permission	No permission	No permission
Package	Receiver\sendBroadcast	Send not require P	Send require P	Send not require P	Send require P
In Permission	require P	onReceive	onReceive	Permission Denial: broadcasting Intent	Permission Denial: broadcasting Intent
In Permission	not require P	onReceive	onReceive	onReceive	onReceive
No Permission	require P	onReceive	Permission Denial: receiving Intent	Permission Denial: broadcasting Intent	Permission Denial: broadcasting Intent Permission Denial: receiving Intent
No Permission	not require P	onReceive	Permission Denial: receiving Intent	onReceive	Permission Denial: receiving Intent

!. receiver 的 android:permission 属性，表示该receiver只接受具有相应权限的Package的Broadcast消息
                    android:permission="com.hyman.demo.android.broadcast.permission.PERMISSION_PERMISSION"
        >

2. registerReceiver(receiver, intentFilter, PERMISSION, null); 表示该receiver只接受具有相应权限的Package的Broadcast消息

3. sendBroadcast(intent, PERMISSION);表示只有具有相应权限的Package才能接受其所发送的Broadcast消息。

4. ※注意双声明权限此处与activity声明权限不同。Package要求某自定义权限时，需要同时使用 Tag 和 Tag

         android:name="com.hyman.demo.android.broadcast.permission.PERMISSION_PERMISSION" >
