Android Studio Gradle Build Running 特别慢的问题探讨，androidgradle

在运行程序的时候Gradle Build Running 特别慢，一个helloworld都快2min了
1、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//.gradle/(Linux)
/Users//.gradle/(Mac)
C:\Users\\.gradle(Windows)
并在文件中增加：
org.gradle.daemon=true
同时修改项目下的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
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。
2、修改android studio配置
在android studio的配置中，开启offline模式，以及修改配置。实际上的配置和上面的一大段一样，主要是在这个地方配置的只会在ide构建的时候生效，命令行构建不会生效。
