首先，AS/bin/*.exe.vmoptions

#

# *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

#

-Xms256m

-Xmx2048m

-XX:MaxPermSize=512m

-XX:ReservedCodeCacheSize=240m

-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=AndroidStudio2.1

-Didea.platform.prefix=AndroidStudio

其次，用户/.gradle/gradle.properties(没有的直接自己创建属性文件)

# 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

# Project-wide Gradle settings.

再次，

最后，至于很多文章说要打开gradle的离线模式，这里我想根据使用经验说一下，首先做android，你得fq，我并不建议不熟悉gradle的人直接将该模式打开，这是其一，其二使用AS时，一定记得把杀毒软件或者防火墙关闭了，某数字卫士和动物卫士经常导致我编译假死，当时我还来回重装，来回设置。
