问题描述

我想构建一个简单的基于片段的应用程序，但我无法加载lib.

无法获得资源'

全部始于实施'com.android.support:support-v4:28.0.0' 这不起作用

推荐答案

您要么在(应用程序)build.gradle中导入错误的依赖性，要么
您的设备/网络上有一些DNS问题.
您也许也可以尝试一下；将其添加到应用程序build.gradle

repositories {
        maven { url "https://maven.google.com" }
    }

我希望这是因为它们很容易解决.让我知道它是否已解决.

问题描述

I want to build a simple fragment based App, but I can't load the lib.

Could not get resource 'https://dl.google.com/dl/android/maven2/com/android/support/support-fragment/28.0.0/support-fragment-28.0.0.aar'

What I tried:

update Proxy settings
delete Proxy
settings Check
check Connection
Add:

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

buildscript {
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'

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

allprojects {
    repositories {
        google()
        jcenter()
         maven {
             url 'https://maven.google.com'
        }

    }
}

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

Gradle.Properties

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    defaultConfig {
        applicationId "com.example.fragmentmanagementmainactivity"
        minSdkVersion 23
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:2.0.0-beta1'
    testImplementation 'junit:junit:4.13-beta-3'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.android.support:support-v13:28.0.0'
    implementation 'com.android.support:support-fragment:28.0.0'
}

All started with implementation of 'com.android.support:support-v4:28.0.0' which wasn't working

推荐答案

You're either importing a wrong dependency in your (app) build.gradle, or
You've got some DNS problems on your device/network.
You might be able to try this too; Add this to the app build.gradle

repositories {
        maven { url "https://maven.google.com" }
    }

I hope it's either of these because they're easy to solve. Let me know if it got solved.
