以下哪种方式更适合获取Application的实例

1. 在 Application.onCreate() 中初始化静态字段并提供对它的静态访问

   public class MyApplication extends Application {
   
       private static MyApplication sInstance;
   
       @Override
       public void onCreate() {
           super.onCreate();
           sInstance = this;
       }
   
       public static MyApplication getInstance() {
           return MyApplication.sInstance;
       }
   }
   
   public class MyBroadcastReceiver extends BroadcastReceiver {
       @Override
       public void onReceive(Context context, Intent intent) {
           MyApplication application = MyApplication.getInstance();
       }
   }

   public class MyApplication extends Application {
   
       @Override
       public void onCreate() {
           super.onCreate();
       }
   
       public static MyApplication getInstance(Context context) {
           return ((MyApplication) …
