Android Studio Gradle Build Running 特別慢的問題探討，androidgradle
本文的本本win7 64bit 6G
android studio2.1
在運行程序的時候Gradle Build Running 特別慢，一個helloworld都快2min了
1、開啟gradle單獨的守護(hù)進(jìn)程
在下面的目錄下面創(chuàng)建gradle.properties文件：
/home//.gradle/(Linux)
/Users//.gradle/(Mac)
C:\Users\\.gradle(Windows)
并在文件中增加：
org.gradle.daemon=true
同時修改項目下的gradle.properties文件也可以優(yōu)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
同時上面的這些參數(shù)也可以配置到前面的用戶目錄下的gradle.properties文件里，那樣就不是針對一個項目生效，而是針對所有項目生效。
上面的配置文件主要就是做， 增大gradle運行的java虛擬機(jī)的大小，讓gradle在編譯的時候使用獨立進(jìn)程，讓gradle可以平行的運行。
2、修改android studio配置
在android studio的配置中，開啟offline模式，以及修改配置。實際上的配置和上面的一大段一樣，主要是在這個地方配置的只會在ide構(gòu)建的時候生效，命令行構(gòu)建不會生效。
