Android中多线程机制的探究

Exploration of Multithreading Mechanism Based on Android

在Android应用程序的开发过程当中,为了获得最佳的用户体验,首先就要保证应用程序运行流畅。而默认情况下,一个Android应用程序会运行在一个线程中,若任务耗时比较长,就很容易引起线程阻塞,导致应用程序无响应。因而Android提供了解决此问题的两种多线程机制——AsyncTask机制和Handler机制,本文对这两种机制进行详细的讨论。

In the development of Android application program, in order to obtain the best user experience, we should first guarantee that the application runs smoothly. However, by default, an application runs in a thread, if a task takes longer, it＇s easy to cause the thread block and lead the application no responding. Therefore, Android provides two mechanisms to solve this problem： one is AsyncTack and the other is Handler. The paper discusses in detail these two mechanisms.
