Android Studio import Project 的正确姿势_android studio importing android gradle project ma

 import Project 网络下载的项目经常卡住，常见原因有三个：

1、Project自带的gradle与AS当前使用的gradle版本不一致

2、Project生成的AS与本机AS版本差别大

3、Project所引用的第三方库下载不下来

一、针对问题1，修改Project使用本机的gradle版本：

1-1、build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

//apply from: 'config/config.gradle'

apply from: rootProject.file('dependencies.gradle')


buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
//        classpath 'com.android.tools.build:gradle:2.4.0-alpha3'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files

        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'

        // Lambda表达式
        classpath 'me.tatarka:gradle-retrolambda:3.5.0'//retrolambda


        //热修复tinker---------------
        classpath ('com.tencent.tinker:tinker-patch-gradle-plugin:1.9.2')
        //热修复tinker---------------
//        classpath 'com.mcxiaoke.gradle:packer-ng:1.0.7'

    }
}

allprojects {
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

1-2、gradle-wrapper.properties

#Tue Nov 07 09:09:35 CST 2017
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

二、针对第二个问题，AS每次升级导致的差异不一，需要区别对待。比如从2到3的build如下：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

//apply from: 'config/config.gradle'

apply from: rootProject.file('dependencies.gradle')


buildscript {
}

allprojects {
    repositories {

        maven {
            url "https://jitpack.io"
        }
        google()

        jcenter()
        mavenCentral()
        maven { url 'https://oss.sonatype.org/content/repositories/snapshots' }

        maven {
            url "http://mvn.gt.igexin.com/nexus/content/repositories/releases/"

        }

//        maven { url '/Users/Felix/Library/Android/sdk/extras/android/m2repository' }

        flatDir{
            dirs 'libs'
        }

        maven{ url 'https://dl.bintray.com/tinker/maven'}
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

处理完以上两步，就可以愉快滴打开AS来import Project了，一般情况下能够进入到AS工作区。如果10min还是进不去，可能就是问题3了，需要继续第三部处理。

三、问题3一般需要网络fanqiang才得行，打开gradle.properties设置网络代理，然后再打开AS来import Project
