Question

我的机器上没有互联网连接（由于某些原因），我想在它上面使用Android studio（3）而不依赖互联网。

我创建了一个非常简单（默认）的应用程序，但是出现了很多错误，我将gradle更改为本地并删除/设置了离线工作选项，但没有任何效果。

错误：

的build.gradle（APP）：

apply plugin: 'com.android.application'

   android {
    compileSdkVersion 26
    defaultConfig {
    applicationId "com.example.administrator.myapplication"
    minSdkVersion 23
    targetSdkVersion 26
    versionCode 1
    versionName "1.0"

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

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.+'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'

 }

的build.gradle（项目）：

buildscript {

repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.0.0'


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

allprojects {
    repositories {
       google()
       jcenter()
   }
}

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

您第一次需要连接到互联网，以便可以获取所有依赖项。一旦完成，您就不再需要互联网了。

但是，如果您再次尝试构建，Android Studio（gradle）仍将尝试连接到Internet以刷新依赖项。如果你不能在线，那么你需要告诉Android Studio（即gradle）离线工作。

转到Android Studio's Preferences -> Build, Execution, Deployment -> Offline Work

启用此选项，gradle将开始脱机工作。

注意：com.android.support:appcompat-v7:26.+.在这里不起作用。您需要提及特定工件ID而不是+。

如何删除android studio上的所有依赖项？
