优化Android Studio/Gradle构建
使用Android Studio进行开,随着项目的增大,依赖库的增多,构建速度越来越慢,现在最慢要6分钟才能build一个release的安装包,在网上查找资料,发现可以通过一些配置可以加快速度,这里跟大家分享一下。
开启gradle单独的守护进程在下面的目录下面创建gradle.properties文件: - /home/<username>/.gradle/ (Linux)
- /Users/<username>/.gradle/ (Mac)
- C:\Users\<username>\.gradle (Windows)
- 把下面配置复制gradle.properties文件也可以优化:
- # Project-wide Gradle settings.
- # IDE (e.g. Android Studio) users:
- # Settings specified in this file will override any Gradle settings
- # configured through the IDE.
- # For more details on how to configure your build environment visit
- # http://www.gradle.org/docs/current/userguide/build_environment.html
- # The Gradle daemon aims to improve the startup and execution time of Gradle.
- # When set to true the Gradle daemon is to run the build.
- # TODO: disable daemon on CI, since builds should be clean and reliable on servers
- org.gradle.daemon=true
- # Specifies the JVM arguments used for the daemon process.
- # The setting is particularly useful for tweaking memory settings.
- # Default value: -Xmx10248m -XX:MaxPermSize=256m
- org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
- # When configured, Gradle will run in incubating parallel mode.
- # This option should only be used with decoupled projects. More details, visit
- # http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects
- org.gradle.parallel=true
- # Enables new incubating mode that makes Gradle selective when configuring projects.
- # Only relevant projects are configured which results in faster builds for large multi-projects.
- # http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:configuration_on_demand
- org.gradle.configureondemand=true
复制代码同时上面的这些参数也可以配置到前面的用户目录下的gradle.properties文件里,那样就不是针对一个项目生效,而是针对所有项目生效。 上面的配置文件主要就是做, 增大gradle运行的java虚拟机的大小,让gradle在编译的时候使用独立进程,让gradle可以平行的运行。 1.申请大内存 installation path\studio64.exe.vmoptions or studio.exe.vmoptions 使用文本编辑器打开,找到起始两行,如下 -Xms128m
-Xmx750m
修改最小值和最大值,建议为 -Xms256m
-Xmx2048m
2 优化编译 file->setting->compile 勾选除第二项之外的其他选项,并在VM options里填入: -Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
经过测试,编译速度有很大提升,比较大的项目从之前的5-8分钟可以减少到1-2分钟。
用命令行Build 可以参考这个讨论串 https://plus.google.com/u/0/+RicardoAmaral/posts/e9PG6vSN5w3 gradle assembleDebug 实测速度快50%左右 原理不明 回头写个脚本 build完成再自动安装运行应该就好了
我觉得TMD还是把公司的破电脑扔了换个新的才能从根本上解决问题 |
