Android Studio Gradle编译优化方法

前言：最近发现Gradle项目编译越来越慢，有时甚至需要好几十分钟，实在是让人难以忍受。于是，便搜寻于网络，经过验证，发现此方案尤其有效，故留此博客，以备以后之需。

第1步：

打开AS安装所在的位置，用记事本打开studio64.exe.vmoptions文件。具体如图：

第2步：

打开“studio64.exe.vmoptions”文件后修改里面的值，修改后如下：

## *DO NOT* modify this file directly. If there is a value that you would like to override,# please add it to your user specific configuration file.## See http://tools.android.com/tech-docs/configuration#-Xms2048m-Xmx2048m-XX:MaxPermSize=2048m-XX:ReservedCodeCacheSize=1024m-XX:+UseConcMarkSweepGC-XX:SoftRefLRUPolicyMSPerMB=50-da-Djna.nosys=true-Djna.boot.library.path=-Djna.debug_load=true-Djna.debug_load.jna=true-Dsun.io.useCanonCaches=false-Djava.net.preferIPv4Stack=true-XX:+HeapDumpOnOutOfMemoryError-Didea.paths.selector=AndroidStudio2.0-Didea.platform.prefix=AndroidStudio

第3步：

打开你的项目中的“gradle.properties”文件复制如下内容：

# 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 serversorg.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=256morg.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_projectsorg.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_demandorg.gradle.configureondemand=true

第4步：

修改gradle-wrapper.properties文件,如图：

第5步：
