Failed to resolve: com.google.firebase:firebase-core:16.0.1
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
}
https://firebase.google.com/docs/android/setup
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.
Add maven { url "https://maven.google.com" } to your root level build.gradle file
repositories {
maven { url "https://maven.google.com" }
flatDir {
dirs 'libs'
}
}
