在Android Studio中打开别人的Android项目

拿到一个别人的Android项目，经常无法直接很顺利的在自己的Android Studio中运行，如果不想重新下载一堆额外的插件，只需要修改三个文件的内容即可。
我们假设项目名称叫master，需要修改的文件如下：

master\build.gradle
master\app\build.gradle
master\gradle\wrapper\gradle-wrapper.properties

master\build.gradle

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

buildscript {
    
    repositories {   
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
		google()
        jcenter()
        
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.2.0"
        

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

allprojects {
    repositories { 
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
		google()
        jcenter()
        
    }
}

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

classpath "com.android.tools.build:gradle:4.2.0"

只需要把这句换成自己本机的Android Studio版本即可
kotlin同理，改成自己编译器的版本，如：ext.kotlin_version = '1.3.71'

master\app\build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 30

    defaultConfig {
        applicationId "com.xinghe.course.mydata"
        minSdkVersion 16
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

对于这个文件，我们应该关注的是:

compileSdkVersion 30
minSdkVersion 16
targetSdkVersion 30

统统改成本机Android Studio预设的值

master\gradle\wrapper\gradle-wrapper.properties

#Tue May 05 20:26:29 CST 2020
distributionBase=GRADLE_USER_HOME
distributionUrl=https\://services.gradle.org/distributions/gradle-6.7.1-bin.zip
distributionPath=wrapper/dists
zipStorePath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME

这里要修改的是gradle的版本,一般直接将自己本机Android Studio的这个文件内容直接全部复制过来就行或者单独修改Url：

distributionUrl=https://services.gradle.org/distributions/gradle-6.7.1-bin.zip

如何快速获取本机Android Studio相关预设和版本

直接自己新建一个项目，然后去对应的文件里把对应的需要更改的内容直接复制过来即可
