6:

 

1：client 和server 的aidl文件包名要保持一致
2：通常使用时，应该是双向通信，在使用时在client端也加入service，接受server端处理后的结果
3: targetSdkVersion >= 30 的时候，需要在配置文件加入需要进来交互的app的applicationId。如下:

 

<manifest> 
...
 <queries>
        <package android:name="com.example.binder_client"/>  // 如果是client端，需要与server端交互，这里的package name要写server端demo的applicationid
  </queries>
...
</manifest>
