提问by N Sharma
I have imported a project in Android Studio that was built in it. I require v4 and v7 library in the project. This is how my build.gradle looks like
我在其中内置的 Android Studio 中导入了一个项目。我在项目中需要 v4 和 v7 库。这就是我的 build.gradle 的样子
build.gradle
构建.gradle
apply plugin: 'android-library'
android {
compileSdkVersion 19
buildToolsVersion '20'
defaultConfig {
applicationId 'com.example.sdk'
minSdkVersion 9
targetSdkVersion 19
versionCode 1
versionName '1.0'
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
productFlavors {
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:20.0.+'
compile 'com.android.support:support-v4:20.0.+'
}
When I sync with gradle then it always gives error message
当我与 gradle 同步时，它总是给出错误消息
Failed to find: com.android.support:support-v4:20.0.+ & Failed to find: com.android.support:appcompat-v7:20.0.+

The Androidsupport repository was missing,So go to Android SDK, install the Android Support Repositoryand Android Support Library.
Also you can use the following
该Android支持库已丢失，因此去Android SDK，安装Android Support Repository和Android Support Library。您也可以使用以下
compile 'com.android.support:support-v4:20.0.0'
compile 'com.android.support:appcompat-v7:20.0.0'
instead of
代替
compile 'com.android.support:appcompat-v7:20.0.+'
compile 'com.android.support:support-v4:20.0.+'

add maven to your gradle file (project)
将 maven 添加到您的 gradle 文件（项目）
allprojects {

}
}
and use this gradle wrapper:
并使用此 gradle 包装器：
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip
and downgrade to gradle plugin to be 2.3.1
并将gradle插件降级为2.3.1
classpath 'com.android.tools.build:gradle:2.3.1'
