进程的生命期 Android系统会尽量维持一个进程的生命,直到最终需要为新的更重要的进程腾出内存空间.为了决定哪个该杀哪个该留,系统会跟据运行于进程内的组件的和组件的状态把进程置于不同的重要性等级.当需要系统资源时,重要性等级越低的先被淘汰. 重要性等级被分为5个档.下面列出了不同类型的进程的重要性等级(第一个进程类型是最重要的,也是最后才会被杀的): 1前台进程 前台进程是用户当前正在使用的进程.只有一些前台进程可以在任何时候都存在.他们是最后一个被结束的,当内存低到根本连他们都不能运行的时候…

应用程序的状态 IOS的应用程序一共有5种状态. Not running(未运行):程序未启动 Inactive(未激活):其他两个状态切换时出现的短暂状态.唯一在此状态停留时间比较长的情况是:当用户锁屏时?或者系统提示用户去响应Alert窗口(如来电.信息)时 Active(激活):在屏幕上显示的正常运行状态,该状态下可以接收用户输入并更新显示 Backgroud(后台):程序在后台且能执行代码.用户按下Home键不久后进入此状态(先进入了Inactive状态,再进入Background状态)…

本文主要讲述了App的启动流程.Application的生命周期以及进程的回收机制. 在绝大多数情况下,每一个Android应用都在自己的Linux进程中运行.当需要运行某些代码时,进程就会被创建.进程将保持运行直到不再需要,当其他应用有需要的时候,系统会释放该进程的内存. 一个不常见但很基础的Android特性是,一个应用进程的生命周期并不是由应用本身直接控制的.它是由系统根据正在运行的程序,对用户的重要程度以及所占用的内存,综合去管理的. 1. App启动流程 此处讨论的是第一次启动App.…
