效果图示例：

//负责发送广播的应用

1、布局只有一个发送广播按钮

2、在配置清单里添加权限(自定义)

代码

 <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.example.broadcast"android:versionCode="1"android:versionName="1.0" ><uses-sdkandroid:minSdkVersion="8"android:targetSdkVersion="21" /><!-- 自定义一个权限 --><permission android:name="com.example.permission.MyReceiver"/><uses-permission android:name="com.example.permission.MyReceiver"/><applicationandroid:allowBackup="true"android:icon="@drawable/ic_launcher"android:label="@string/app_name"android:theme="@style/AppTheme" ><activityandroid:name=".MainActivity"android:label="@string/app_name" ><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity></application>
</manifest>

3、MainActivity.java类

代码

 public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);}//发送广播按钮事件监听public void sendBroad(View view) {Intent intent = new Intent();//这里setAction中的action是别的应用接收本应用发送的广播的action（相当于暴露给其他应用的路径）intent.setAction("com.example.broadcast.MyReceiver");/** intent.putExtra("data", "无序广播发送的数据"); *sendBroadcast(intent);//发送*/// 有序广播的发送intent.putExtra("data", "有序广播发送的数据");// 有序广播发送的权限在配置清单里自定义(第二个参数)//发送广播的方法sendOrderedBroadcastsendOrderedBroadcast(intent, "com.example.permission.MyReceiver");}
}

==================================================

发送广播端做好后做另外应用的广播接收端(跨应用)

//另外的应用(广播接收者)有2个有序广播接收者 把接收到的结果打印到日志猫

//广播接收者类都要继承BroadCastReceiver类

4、在配置清单里静态注册2个广播接收者和添加权限(该权限是发送广播端自定义的权限)

配置清单代码

 <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.example.orderbroadcast"android:versionCode="1"android:versionName="1.0" ><uses-sdkandroid:minSdkVersion="8"android:targetSdkVersion="21" /><!-- 另外一个应用自定义的权限 --><uses-permission android:name="com.example.permission.MyReceiver"/><applicationandroid:allowBackup="true"android:icon="@drawable/ic_launcher"android:label="@string/app_name"android:theme="@style/AppTheme" ><activityandroid:name=".MainActivity"android:label="@string/app_name" ><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity><!-- priority有序广播范围是-1000到1000 数值越大优先权越高 --><receiver android:name=".OrderBroadOne"><intent-filter android:priority="1"><action android:name="com.example.broadcast.MyReceiver"/></intent-filter></receiver><receiver android:name=".OrderBroadTwo"><intent-filter android:priority="2"><action android:name="com.example.broadcast.MyReceiver"/></intent-filter></receiver></application>
</manifest>

‍

5、配置清单配置好后编写源文件有2个类(2个有序广播接收者)一个OrderBroadOne.java类一个OrderBroadTwo.java类

OrderBroadOne.java类

代码

 public class OrderBroadOne extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubString data = intent.getStringExtra("data");Log.i("data", "OrderBroadOne data = " + data);//把结果打印到日志猫}
}

OrderBroadTwo.java类

代码

 public class OrderBroadTwo extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubString data = intent.getStringExtra("data");Log.i("data", "OrderBroadTwo data = " + data);//把结果打印到日志猫}
}

6、最后先运行广播接收者的应用(部署好广播接收者)，在运行广播发送端发送广播 最后在日志猫查看打印信息
