我有一个应用程序，它是在同一时间广播发送者和标准动作android.intent.action.SET_WALLPAPER接收器。我想做一些东西，只有在一个情况下，当其他应用程序播放此意图。

I have an application that is at the same time a broadcast sender and receiver of standard action android.intent.action.SET_WALLPAPER. I want to do some stuff only in a case when another application broadcasted this intent.

有什么方法来决定谁在一个BroadcastReceiver中的onReceive方法启动的广播？

Is there any way to determine who initiated a broadcast in onReceive method of a BroadcastReceiver?

推荐答案

没有。

如果你只想做一些事情，当一个动作被另一个应用程序的广播（即不是你），我想这应该很容易判断您的应用程序的没有的发送该广播，并因此，它是别人。

If you only want to do something when an action was broadcast by another app (i.e. not yours), I imagine it should be easy to determine that your app didn't send this broadcast, and therefore it was someone else..
