我是Android Studio平台的新手。我收到此错误 “无法解决:com.android.support:appcompat-v7:jar”
当前,我的Android Studio版本是3.5.0。 我在build.gradle存储库中添加了google()
这是我的build.gradle(项目)
buildscript {
repositories {
jcenter()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.5.0'
classpath 'com.google.gms:google-services:3.2.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
google()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
这是我的build.gradle(模块应用)
apply plugin: 'com.google.gms.google-services'
android {
compileSdkVersion 28
buildToolsVersion '28.0.3'
defaultConfig {
applicationId "com.kartik.barcode"

}
我仍然收到此错误: 错误:无法解决:com.android.support:appcompat-v7:jar 在项目结构对话框中显示 受影响的模块:应用
答案 0 :(得分:2)
您应该使用 PROPER
版本。在此依赖项中没有 jar 。
使用稳定
implementation 'com.android.support:appcompat-v7:28.0.0' //28.0.0-alpha1
仅供参考
请通过更新以下版本来解决版本冲突: google-services插件或更新其版本 com.google.android.gms到11.4.2
您应该升级到以下版本
implementation 'com.google.android.gms:play-services-auth:17.0.0'
如果使用升级的类路径,这将是一个很好的方法
classpath 'com.google.gms:google-services:4.2.0'
