当一回Android Studio 2.0的小白鼠

上个星期就放出了Android studio出2.0的消息,看了一下what's new 简直抓到了那个蛋疼的编译速度痛点.在网上稍微搜索了一下后发现基本都是介绍视频.一番挣扎后(因为被这IDE坑过几次),于是决定自己当一回小白鼠实验一下.

instant run

准备

首先,是把升级跳到最不稳定的频道,check 一下然后 update and restart,这不必说.唯一值得讲的一点在于,下完安装的时候会耗尽磁盘的资源,很卡.然后第一次打开的时候记得导入之前的设置.

床说中的瞬间执行

instant run需要gradle 2.8+好在ide认识到这一点,点自动更新工程,等待结果完成即可.

更新之后,会发现gradle用上了2.8.然后下面的设置也不再是灰色.表明设置可用.我建议只勾选第一项

此外,应用instant run的AVD需要api14+

不足

但是目前,该功能还是有些不完善的.这里引用原文

Here are some code changes that Instant Run does not currently support:

Add/remove/change annotations

Add/remove/change an instance field

Add/remove/change a static field

Add/remove a static method signature

Change a static method signature

Add/remove an instance method

Change an instance method signature

Changing which parent class the current class inherits from

Change the list of implemented interfaces

Changing static initializer of a class

使用和体会

代码改动之后,点击run(此时的run左边有个小闪电的图标),之后即可完成迅速编译.我这边试了一下,大概2s以内.

11:23:46 Executing tasks: [:app:incrementalDebugSupportDex]
11:23:48 Gradle build finished in 1s 948ms
11:23:48 Instant Run: Instant Run applied code changes.
You can restart the current activity by clicking here or pressing Ctrl+Shift+R anytime.

You can also configure restarts to happen automatically. (Dismiss, Dismiss All)

还是比较快的~
