问题描述

我用Debug.startMethodTracing我的目的，并在输出文件中，我可以看到（我不使用IPC）：

I use Debug.startMethodTracing for my purposes and in the output file I can see(I don't use IPC):

8   Binder Thread #2
7   Binder Thread #1

有关它是什么？

推荐答案

捆扎线重新presents服务的一个单独的线程。粘合剂是，它提供进程间通信机制。

Binder thread represents a separate thread of your service. Binder is a mechanism that provides Inter Process Communication.

让我们来看一个例子。试想一下，你的服务流程B（见图）。而你有一个与该服务B（这个应用程序是一个，例如，进程A）交流几个应用程序。因此，一个服务B应该同时向不同的应用提供不同的结果。因此，你需要为不同的应用程序中运行的服务B多个副本。 Android的运行在进程B的不同的线程，这些线程这些副本被称为粘合剂线程＃N。

Let's consider an example. Imagine that you have service Process B (see picture). And you have several applications that communicate with this service B (one of this application is, for instance, Process A). Thus, one service B should provide different results simultaneously to different applications. Thus, you need to run several replicas of Service B for different applications. Android runs these replicas in different threads of the Process B and these threads are called "Binder Thread #N".
