跨应用(跨进程)发送广播和接收广播

跨应用发送和接收广播,与同应用下的情况差不多,只需要添加一个权限,以及配置一下receiver的android:process属性即可

发送广播的应用中:

Intent intent = new Intent("info.zhegui.receiver.interprocess");
sendBroadcast(intent);

 注意要在manifest.xml添加接收广播的权限,这个权限是receiver自定义的

<uses-permission android:name="info.zhegui.receiver.RECEIVE"/>

接收广播的应用中:

public class MyReceiver extends BroadcastReceiver {
	private final String TAG = this.getClass().getName();

	@Override
	public void onReceive(Context content, Intent intent) {
		Log.i(TAG, "intent:" + intent);
	}

}

 在manifest.xml中添加自定义权限,以及配置receiver的几个属性

<permission android:name="info.zhegui.receiver.RECEIVE" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <receiver
            android:name="info.zhegui.receiver.MyReceiver"
            android:exported="true"
            android:process=":remote" >
            <intent-filter>
                <action android:name="info.zhegui.receiver.interprocess" />
            </intent-filter>
        </receiver>
    </application>

需要注意的三个地方:

1,自定义权限

2,android:exported="true"

3,android:process=":remote" (有时候可以不要该属性)

动态注册也是可能的。
