在Android Studio中，我收到一条错误消息，提示"Packages unavailable".而且我需要的软件包不可用 [英] In Android studio, I'm getting an error that says "Packages unavailable" and that a package I need is not available

问题描述

在Android Studio中，

In Android Studio,

我在构建应用程序时遇到错误.

I'm getting an error about building my app.

Error:Failed to find Build Tools revision 26.1.0
<a href="install.build.tools">Install Build Tools 26.1.0 and sync project</a>

这将导致一个蓝色的安装链接，但是当我单击它时，出现一条错误消息，告诉我软件包不可用"和软件包不可用".

This results in a blue install link, but when I click it I get an error telling me that, "Package Unavailable" and that "Packages are unavailable."

这是我的build.gradle的样子

Here's what my build.gradle looks like

apply plugin: 'com.android.application'

android {
compileSdkVersion 26
lintOptions {
    abortOnError false
}
defaultConfig {
    applicationId "com.example.leoconnelly.connexus"
    minSdkVersion 23
    targetSdkVersion 26
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    buildToolsVersion '26.1.0'

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

dependencies {

implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
implementation 'com.android.support:design:26.1.0'
compile 'com.squareup.picasso:picasso:2.5.2'

//Helpshift
// use version 26.1.0 instead of 26.0.2
implementation 'com.android.support:design:26.1.0'
implementation 'com.android.support:recyclerview-v7:26.1.0'
implementation 'com.android.support:cardview-v7:26.1.0'

implementation('com.helpshift:android-helpshift-en-aar:6.4.2') {
    exclude group: 'com.android.support'
    exclude module: 'design'
    exclude module: 'recyclerview'
    exclude module: 'cardview-v7'

}


}

如何解决此问题?我已经尝试过弄乱我的SDK管理器.我到目前为止发现的所有解决方案都行不通.

How do I resolve this issue? I've tried messing wth my SDK manager already. All the solutions I've found insofar do not work.

我试图在一个全新的项目上安装26.0.1，但我遇到了同样的问题.

I tried installing 26.0.1 on an a brand new project and I had the same issue.

推荐答案

您只需要移至SDK Platform 8.0.

You just have to move to SDK Platform 8.0.

对于目标和最小api来说，它不会为您带来任何改变，并且这些应用仍可以在较旧的Android版本上运行.

It won't change things for you regarding target and min api, and the apps will still work on older Android version.

只需下载此文件并将其解压缩即可.

Just download this file and extract it.

https://dl.google.com/android /repository/build-tools_r26.0.2-windows.zip

从[android-8.1.0]复制所有文件，然后将其移至

copy all files from [android-8.1.0] and move them into

C:\Users\user\AppData\Local\Android\Sdk\build-tools\26.0.1
