问题描述
我实际上只是第一次开始应用程序开发,而当我创建一个新项目时,默认项目将无法构建.我尝试在Google和SO上查找这些错误,并发现了一些错误,但它们的解决方案不起作用.鉴于我根本没有编辑文件,因此我认为这是Android Studio设置不正确但无法解决的问题.错误如下:
I am literally just starting app development for the first time and the default project when I create a new one will not build. I have tried looking on Google and SO for these errors and have found some but their solutions do not work. Given that I have not edited the files at all, I presume it is an issue with Android Studio not being setup properly but can't figure it out. The errors are as follows:
Error:Failed to resolve: com.android.support:support-v4:25.2.0
Install Repository and sync project
Open File
Show in Project Structure dialog
Error:(23, 24) Failed to resolve: com.android.support.test.espresso:espresso-core:2.2.2
Install Repository and sync project

Error:(26, 13) Failed to resolve: com.android.support:appcompat-v7:26.+
Install Repository and sync project

它指向的build.gradle文件如下:
The build.gradle file it points to is as follows:
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "26.0.0"
defaultConfig {
applicationId "com.extremecomputing.spotzz"
minSdkVersion 17
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:26.+'
compile 'com.google.android.gms:play-services-maps:11.0.1'
testCompile 'junit:junit:4.12'
}
我尝试过一个以前的项目,该项目创建了一些我在网上找到的东西.如他们所建议的版本中的+
可能会导致无法预测的构建,但事实并非如此.一个人在dependencies
部分中推荐了几行编译行,它暂时更改了错误,说我需要下载某些内容,然后我又恢复了原来的错误.我还尝试确保SDK工具已更新,并且看起来确实如此.任何建议将不胜感激.
I have tried with a previous project that I had created a few things I found online. Such as they had recommended the +
in the version could cause unpredictable builds, but that wasn't it. One had recommended a few compile lines in the dependencies
section, it changed the errors for a moment saying I needed to download something, I did then it went back to the original errors. I also have tried to make sure that the SDK tools are updated, and they appear to be. Any suggestions would be greatly appreciated.
推荐答案
尝试一下:
- 在Android Studio中,打开工具"->"Android"->"SDK管理器"
- 在"SDK工具"标签下,取消选中导致问题的库
- 单击应用"将其卸载
- 重新检查相同的库,单击应用"以重新安装它们
- 关闭SDK Manager并运行Gradle同步/构建
