我知道这个问题已经被问了很多,但答案总是要转到SDK Manager并确保安装/更新Google Play服务和Google Repository。
我的更新和安装。 Google Play服务版本为44,Google Repository版本为版本58.此外,如果我检查Android Studio的更新,它会说我安装了最新版本。所以,这不是问题所在。任何人都可以帮助我吗?
这是我的app build.gradle文件
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion '25.0.2'
defaultConfig {
applicationId "com.angelakarl.flashchatnewfirebase"
minSdkVersion 16
targetSdkVersion 25
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:design:25.3.1'
compile 'com.google.firebase:firebase-database:11.2.2'
compile 'com.google.firebase:firebase-auth:11.2.2'
}
apply plugin: 'com.google.gms.google-services'
这是我的另一个build.gradle文件
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
classpath 'com.google.gms:google-services:3.1.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
我得到的错误是
错误:(27,13)无法解决:com.google.firebase:firebase-auth:11.2.2
错误:无法解决:com.google.firebase:firebase-core:11.2.2
错误:(26,13)无法解决:com.google.firebase:firebase-database:11.2.2
答案 0 :(得分:2)
请将Google的Maven资源库添加到您的项目级build.gradle文件中:
allprojects
{
repositories
{
jcenter()
maven { url "https://maven.google.com" // Google's Maven repository}
}
}
