如何Android应用程序有多个进程？ [英] How can an Android application have more than one process?

问题描述

我已经开发了一个Android应用程序，有1流程和2服务。但我注意到，谷歌服务有2个进程和1服务。它如何能有2个进程？我做了一些读数进程和线程尝试了解更多有关进程。它谈论有一个清单条目，但没有一个具体的例子，我不明白这一点。有人可以解释一个Android应用程序如何有超过1的过程，并提供了一​​个具体的例子？

I have developed an Android application that has 1 process and 2 services. But I noticed that "Google Services" has 2 processes and 1 service. How can it have 2 processes? I did some reading at Processes and Threads to try to understand more about processes. It talks about having a manifest entry, but without a concrete example I don't get it. Can someone explain how an Android application can have more than 1 process and provide a concrete example of that?

推荐答案

您可以指定安卓程序=：远程在你的清单中有一个活动/服务在一个单独的进程中运行。

You can specify android:process=":remote" in your manifest to have an activity/service run in a seperate process.

远程是远程过程的只是名字，你可以调用它任何你想要的。如果你想几个活动/服务，在同一个进程中运行，只要给它相同的名称。

The "remote" is just the name of the remote process, and you can call it whatever you want. If you want several activities/services to run in the same process, just give it the same name.

<activity android:name=".RemoteActivity" android:label="@string/app_name" android:process=":RemoteActivityProcess"/>

我已经写博客文章而回解释属性，以及如何调试远程进程。

I've written a blog post a while back explaining the attribute, and how to debug the remote process.
