如何从另一个类(当为onUnityAdsFinish时)触发有状态窗口小部件中的函数？

public class MyBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals("com.example.ACTION_XXX")) {
            // 触发有状态窗口小部件中的函数
            YourWidgetClass.updateWidgetFunction();
        }
    }
}

public class YourWidgetClass extends AppWidgetProvider {
    // ...

    public static void updateWidgetFunction() {
        // 实现更新有状态窗口小部件的函数逻辑
    }

    // ...
}

<application>
    <!-- 注册广播接收器 -->
    <receiver
        android:name=".MyBroadcastReceiver"
        android:exported="false">
        <intent-filter>
            <action android:name="com.example.ACTION_XXX" />
        </intent-filter>
    </receiver>

    <!-- 注册有状态窗口小部件 -->
    <receiver
        android:name=".YourWidgetClass">
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
        </intent-filter>
        <meta-data
            android:name="android.appwidget.provider"
            android:resource="@xml/widget_info" />
    </receiver>
</application>

public class AnotherClass {
    private void onUnityAdsFinish() {
        // 当满足条件时发送广播消息
        Intent intent = new Intent("com.example.ACTION_XXX");
        context.sendBroadcast(intent);
    }
}
