开发两款Android应用程序和两者之间的通信
我正在开发两个应用程序名A和B
I am developing two applications names A and B.
应用程序A为活动命名MainActivity，服务，称为UpdateService，broadcastreciever称为UpdateReceiver。
Application A as activity named MainActivity, service called UpdateService, broadcastreciever called UpdateReceiver.
应用程序B为命名活动TestActivity，服务，称为DoService，broadcastreciever称为DoReceiver。
Application B as activity named TestActivity, service called DoService, broadcastreciever called DoReceiver.
在我applicayion B，我要访问一些方法和MainActivity code这是在应用程序A
In my applicayion B, I want to access few methods and code from MainActivity which is in Application A.
在这种方式，我需要完全控制中的应用A code到accesss它在我的应用程序B
In this way I need full control of Application A code to accesss it in my application B
我怎样才能实现呢？
您无法直接访问不同的应用程序活动的方法。
You cannot directly access methods of Activity in different app.
广播会工作，但如果你想要更多控制（即调用远程方法）考虑绑定到远程服务中的其他应用程序或使用信使和处理程序进行通信。
Broadcast would work but if you want more control (i.e. invoke remote methods) consider binding to a remote service in the other app or use Messenger and handler to communicate.
下面是跨应用通信
