说明
本文主要介绍基于Android Studio开发android project的一些配置。
1、Android Studio安装及基本配置
这里用的版本是3.2
具体安装过程不再详述
2、gradle-wrapper.properties
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=file:///d:/Application/Android/gradle/gradle-4.6-all.zip #gradle的本地zip包
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
3、local.properties
## This file is automatically generated by Android Studio.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file should *NOT* be checked into Version Control Systems,
# as it contains information specific to your local configuration.
#
# Location of the SDK. This is only used by Gradle.
# For customization when using a Version Control System, please read the
# header note.
sdk.dir=D\:\\Application\\Android\\android-sdk
4、gradle.properties
## For more details on how to configure your build environment visit
# http://www.gradle.org/docs/current/userguide/build_environment.html
#
# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
# Default value: -Xmx1024m -XX:MaxPermSize=256m
org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -X:+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
#Tue Nov 27 22:22:56 CST 2018
org.gradle.daemon=true
注意：此处不需要设置代理，设置代理后有可能会导致后面gradle及相关依赖无法下载
注意：如果提示如下错误
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=512m; support was removed in 8.0
Unrecognized option: -X:+HeapDumpOnOutOfMemoryError
可根据自己使用的jdk情况修改，如：
org.gradle.jvmargs=-Xmx2048m -Xmx512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
4、Project层面的build.gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
#下面两个国内可以直接访问，并不需要配置代理
google() #一定要放在第一个，否则会导致“Could not find aapt2-windows.jar”的问题

备注：本文将http://maven.aliyun.com/mvn/view中的path全部配置到maven中了，如：maven { url'http://maven.aliyun.com/repository/grails-core' }

另外，本文没有用内嵌的maven repository，具体设置如下图：

5、Module层面的build.gradle
applyplugin:'com.android.application'
android {
compileSdkVersion28
defaultConfig {
applicationId "com.taoping.testnew"
minSdkVersion19
targetSdkVersion28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir:'libs',include: ['*.jar'])
implementation'com.android.support:appcompat-v7:28.0.0-alpha1'
implementation'com.android.support.constraint:constraint-layout:1.1.0'
testImplementation'junit:junit:4.12'
androidTestImplementation'com.android.support.test:runner:1.0.2'
androidTestImplementation'com.android.support.test.espresso:espresso-core:3.0.2'
}
5、gradle的设置
