Failed to resolve: com.google.firebase:firebase-core:16.0.1
I'm trying to add firebase cloud storage to my app. Below is the app build.gradle. But it says: Failed to resolve: com.google.firebase:firebase-core:16.0.1. Why? There is no firebase-core in the dependencies at all.
apply plugin: 'com.android.application'
android {
compileSdkVersion 27
defaultConfig {
applicationId "com.louise.udacity.mydict"
minSdkVersion 15
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
implementation 'com.google.firebase:firebase-storage:16.0.1'
implementation 'com.google.firebase:firebase-auth:16.0.1'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.google.cloud:google-cloud-storage:1.31.0'
implementation 'com.firebase:firebase-jobdispatcher:0.8.5'
}
apply plugin: 'com.google.gms.google-services'
Solution 1:
From the docs:-
Your app gradle file now has to explicitly list
com.google.firebase:firebase-core
as a dependency for Firebase services to work as expected.
Add:
implementation 'com.google.firebase:firebase-core:16.0.1'
and in top level gradle file use the latest version of google play services:
classpath 'com.google.gms:google-services:4.0.2'
https://firebase.google.com/support/release-notes/android
https://bintray.com/android/android-tools/com.google.gms.google-services
Note:
You need to add the google()
repo in the top level gradle file, as specified in the firebase docs and also it should be before jcenter()
:
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.3'
classpath 'com.google.gms:google-services:4.0.2'
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

Solution 2:
As @Peter Haddad mentioned above,
To fix this issue I followed Google firebase integration guidelines and did the following changes in my app/build.gradle and project/build.gradle
Follow below mentioned link if you have any doubts
https://firebase.google.com/docs/android/setup
changes in app/build.gradle
implementation 'com.google.android.gms:play-services-base:15.0.2'
implementation "com.google.firebase:firebase-core:16.0.1"
implementation "com.google.firebase:firebase-messaging:17.4.0"
Changes in Project/build.gradle
repositories {
google()
jcenter()
mavenCentral()
maven {
url 'https://maven.fabric.io/public'
}
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.4'
classpath 'com.google.gms:google-services:4.2.0'// // google-services plugin it should be latest if you are using firebase version 16.0 +
}
allprojects {
repositories {
google()// add it to top instead of bottom or somewhere in middle
mavenLocal()
mavenCentral()
maven {
url 'https://maven.google.com'
}
jcenter()
maven {
// All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
url "$rootDir/../node_modules/react-native/android"
}
}
}
Solution 3:
Add maven { url "https://maven.google.com" } to your root level build.gradle file
repositories {
maven { url "https://maven.google.com" }
flatDir {
dirs 'libs'
}
}
Solution 4:
Since May 23, 2018 update, when you're using a firebase dependency, you must include the firebase-core
dependency, too.
If adding it, you still having the error, try to update the gradle plugin in your gradle-wrapper.properties
to 4.5 version:
distributionUrl=https\://services.gradle.org/distributions/gradle-4.5-all.zip
and resync the project.
Solution 5:
I get the same issue and i solved it by replacing :
implementation 'com.google.firebase:firebase-core:16.0.1'
to
implementation 'com.google.firebase:firebase-core:15.0.2'
and everything solved and worked well.
