问题描述

我有我需要获取我创建一个BroadcastReceiver参考Application类的扩展。传递到的onReceive的上下文中是受限制的情况下。有没有一种方法来获得引用到实际的应用程序上下文？

I have an extension of the Application class that I need to obtain reference in a BroadcastReceiver I have created. The context passed into the "onReceive" is a restricted context. Is there a way to obtain reference to the actual application context?

推荐答案

呼叫 getApplicationContext（）在上下文在的onReceive（）提供给您的，就像你会打电话 getApplicationContext（）上的活动。

Call getApplicationContext() on the Context supplied to you in onReceive(), just as you would call getApplicationContext() on an Activity.

我的应用程序的扩展，让我无静态获取引用我需要几个对象。

I have an extension of the Application that allows me to non-statically obtain reference to several objects I need.

虽然语法应用程序不是一成不变的，它具有相同的影响，特别是对于内存泄漏。

While syntactically Application is not static, it has the same impact, particularly with respect to memory leaks.
