Send broadcast and receive broadcast across applications (processes)

Send and receive broadcasts across applications. In the same case as in the same application, you only need to add a permission and configure the Android: process attribute of the receiver.

 

 

In the broadcast sending application:

 

Java code

1. Intent intent = new intent ("info. zhegui. Er er. interprocess ");
2. Sendbroadcast (intent );

Note that you must add the broadcast receiving permission in manifest. xml. This permission is customized by the receiver.

Java code

1. <Uses-Permission Android: Name = "info. zhegui. Receiver. Receive"/>

 

In applications that receive broadcasts:

Java code

1. Public class myreceiver extends broadcastreceiver {
2. Private final string tag = This. getclass (). getname ();
4. @ Override
5. Public void onreceive (context content, intent ){
6. Log. I (TAG, "intent:" + intent );
7. }
9. }

Add custom permissions to manifest. xml and configure several attributes of the receiver.

 

<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>  

 

 

 

Note the following three points:

1. Custom Permissions

2, Android: exported = "true"

3. Android: Process = ": Remote" (This attribute can be skipped sometimes)

 

Dynamic registration is also possible.
