自定義廣播權限例子：
發送者：Demo_BroadcastSend 發出廣播（1、發出無權限廣播按鈕 ， 2、發出帶權限廣播按鈕）
接收者：Demo_BroadcastReceive_A 無自定義廣播權限
接收者：Demo_BroadcastReceive_B 有自定義廣播權限（manifest中）
<uses-permission android:name="com.sdf.userdefined.receiver.permission" />
<permission
android:name="com.sdf.userdefined.receiver.permission"
android:protectionLevel="normal" />
--------------------------------------------------------------------------------
Demo_BroadcastSend發出無權限廣播，Demo_BroadcastReceive_A與Demo_BroadcastReceive_B中的廣播接收器均可接收到改廣播
結果：
[MyReceiver--->B] onReceive : intent = Intent { act=com.sdf.userdefined.receiver.action cat=[receiver] flg=0x10 cmp=com.sdf.demo_broadcastreceive_b/.MyReceiverB (has extras) }
[MyReceiver--->B] onReceive : message = 無 ---> 權限的廣播
[MyReceiver--->A] onReceive : intent = Intent { act=com.sdf.userdefined.receiver.action cat=[receiver] flg=0x10 cmp=com.sdf.demo_broadcastreceive_a/.MyReceiverA (has extras) }
[MyReceiver--->A] onReceive : message = 無 ---> 權限的廣播
--------------------------------------------------------------------------------
步驟1：
Demo_BroadcastSend 中（manifest）定義以下權限：
<uses-permission android:name="com.sdf.userdefined.send.permission" />
<permission
android:name="com.sdf.userdefined.send.permission"
android:protectionLevel="normal" />
步驟2：
Demo_BroadcastReceive_B 中（manifest）定義以下權限：
<uses-permission android:name="com.sdf.userdefined.receiver.permission" />
<permission
android:name="com.sdf.userdefined.receiver.permission"
android:protectionLevel="normal" />
且
Demo_BroadcastReceive_B 中 （ manifest）的廣播接收器加上權限屬性：
android:permission="com.sdf.userdefined.send.permission"
以上兩步驟同時實現才可接收帶權限的廣播
結果：
[MyReceiver--->B] onReceive : intent = Intent { act=com.sdf.userdefined.receiver.action cat=[receiver] flg=0x10 cmp=com.sdf.demo_broadcastreceive_b/.MyReceiverB (has extras) }
[MyReceiver--->B] onReceive : message = 帶 ---> 權限的廣播
