Android15 Framework自定义服务调用package/modules下的EthernetManager接口

一、环境配置

软件系统： Android 15
设备平台：RK3576

二、背景说明

实际项目开发中，往往需要定制Framework 服务，例如突破系统API限制为，APP提供可直接调用协调级API(例如：获取和配置网络端口)
在Android13 Framework自定义服务调用package/modules一文中我们实现framework调用EthernetManager接口，但在Android15上，这一情况又有所不同：
在Framework/base下自定义服务中调用mEthernetManager.getConfiguration()会报错：

frameworks/base/services/core/java/com/android/server/xxx/CustomerManagerService.java:548: error: cannot find symbol
        mEthernetService.setConfiguration(iface, ipConfiguration);
                        ^
  symbol:   method setConfiguration(String,IpConfiguration)
  location: variable mEthernetService of type EthernetManager

对比Android13与Android15此接口代码：

    //////Android13
    /**
     * Get Ethernet configuration.
     * @return the Ethernet Configuration, contained in {@link IpConfiguration}.
     * @hide
     */
    @RequiresPermission(android.Manifest.permission.ACCESS_NETWORK_STATE)
    @SystemApi(client = MODULE_LIBRARIES)
    @NonNull
    public IpConfiguration getConfiguration(@NonNull String iface) {
        try {
            return mService.getConfiguration(iface);
        } catch (RemoteException e) {
            throw e.rethrowFromSystemServer();
        }
    }

    /////Android15
    /**
     * Get Ethernet configuration.
     * @return the Ethernet Configuration, contained in {@link IpConfiguration}.
     * @hide
     */
    @UnsupportedAppUsage(maxTargetSdk = Build.VERSION_CODES.R, trackingBug = 170729553)
    public IpConfiguration getConfiguration(String iface) {
        try {
            return mService.getConfiguration(iface);
        } catch (RemoteException e) {
            throw e.rethrowFromSystemServer();
        }
    }

对比可知代码没变，编译规则变了,Android 15 的 build 系统把“@hide 接口”默认屏蔽掉了

三、代码修改

对需要的接口修改注解，如下：
packages/modules/Connectivity/framework-t/src/android/net/EthernetManager.java

    /**
     * Get Ethernet configuration.
     * @return the Ethernet Configuration, contained in {@link IpConfiguration}.
     * @hide
     */
-   @UnsupportedAppUsage(maxTargetSdk = Build.VERSION_CODES.R, trackingBug = 170729553)
+   @RequiresPermission(android.Manifest.permission.ACCESS_NETWORK_STATE)
+   @SystemApi(client = MODULE_LIBRARIES)
+   @NonNull
    public IpConfiguration getConfiguration(String iface) {
        try {
            return mService.getConfiguration(iface);
        } catch (RemoteException e) {
            throw e.rethrowFromSystemServer();
        }
    }
