我添加了依赖项,并将maven {url“https://maven.google.com”}添加到我的build.gradle
文件中。但仍然会出现错误:
无法解析com.google.firebase:firebase-database:11.4.2
无法解析com.google.firebae:firebase-core:11.4.2
这是root one
中的 build.gradle 文件buildscript {
repositories {
jcenter()
mavenLocal()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.2.2'
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()
mavenLocal()
maven{ url "https://maven.google.com" }
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
以下是app one
中的 build.gradle 文件apply plugin: 'com.android.application'
repositories {
mavenLocal()
flatDir {
dirs 'libs'
}
}
android {
compileSdkVersion 24
buildToolsVersion "24.0.1"
defaultConfig {
applicationId "com.google.firebase.udacity.friendlychat"
minSdkVersion 16
targetSdkVersion 24
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'),
'proguard-rules.pro'
}
}
packagingOptions {
exclude 'META-INF/LICENSE'
exclude 'META-INF/LICENSE-FIREBASE.txt'
exclude 'META-INF/NOTICE'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:design:24.2.0'
compile 'com.android.support:appcompat-v7:24.2.0'
compile 'com.google.firebase:firebase-core:11.4.2'
compile 'com.google.firebase:firebase-database:11.4.2'
// Displaying images
compile 'com.github.bumptech.glide:glide:3.6.1'
}
apply plugin: 'com.google.gms.google-services'
这里有任何帮助!

将compileSdkVersion
更新至至少26.来自https://developers.google.com/android/guides/releases,
“当您将应用的Play服务依赖项升级到11.2.0或更高版本时,还必须更新您应用的build.gradle以指定至少为26(Android O)的compileSdkVersion。”
