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(大致的用处就是,当AndroidStudio挂掉的时候,有个线程唤醒他,保证了AndroidStudio的健壮)
在下面的目录下面创建gradle.properties文件:
/home//.gradle/
(Linux)
/Users//.gradle/
(Mac)
C:\Users\\.gradle
(Windows)
把下面配置复制到gradle.properties文件中:
#
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
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。
