Android Studio Gradle Build Running 特別慢的問題探討，androidgradle

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單獨的守護進程

在下面的目錄下面創建gradle.properties文件：

• /home/<username>/.gradle/ (Linux)
• /Users/<username>/.gradle/ (Mac)
• C:\Users\<username>\.gradle (Windows)

並在文件中增加：

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也可以配置到前面的用戶目錄下的gradle.properties文件裡，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虛擬機的大小，讓gradle在編譯的時候使用獨立進程，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構建的時候生效，命令行構建不會生效。
