Develop Reference

Faild to resolve: firebase-auth-15.0.0

I am new to android development environment and I need to connect my app to firebase but I am getting this error
Failed to resolve: firebase-auth-15.0.0
This error is shown in the statement:
implementation 'com.google.firebase:firebase-auth:15.0.0' //16.0.1
I tried to change the above statement to
implementation 'com.google.firebase:firebase-auth:16.0.3'
But then firebase dependency is not setting up.

You should use firebase-auth:16.0.4 version.
implementation 'com.google.firebase:firebase-auth:16.0.4'
FYI
At first, add rules to your root-level build.gradle file, to include the google-services plugin and the Google's Maven repository:
buildscript {
// ...
dependencies {
// ...
classpath 'com.google.gms:google-services:4.1.0' // google-services plugin
}
}
allprojects {
// ...
repositories {
// ...
google() // Google's Maven repository
}
}
After that, Clean-Rebuild-Run.
Read Add Firebase to Your Android Project

Update the dependency to the following:
implementation 'com.google.firebase:firebase-auth:16.0.4'
Also add firebase-core:
implementation 'com.google.firebase:firebase-core:16.0.4'
https://firebase.google.com/support/release-notes/android
Please also update google-services plugin in top level gradle file:
classpath 'com.google.gms:google-services:4.1.0'

After upgrding to com.google.gms:google-services:3.3.0 I started geting this errors [duplicate]

I am getting the following error:
Cannot change dependencies of configuration ':app:api' after it has been included in dependency resolution.
Updated:
I am able to build using com.google.gms:google-services:3.3.0 when data binding is disabled, but this is not a solution for someone that requires data binding to be enabled.
After Google announced the new sdk versioning system (link), I did the following steps:
I updated the gradle files as directed to include the gms and firebase version numbers separately. Updated the apply plugin line, updated the classpath. I am still getting the error and dont know the reason.
Below are relevant gradle files:

The issue with data binding and the 3.3.0 version of the google-services plugin has been reported here: https://issuetracker.google.com/issues/79122163
As of today, the bug is in the "assigned" state.

UPDATE
I could compile also with
dataBinding.enabled false
In android configuration and version 3.3.0
ORIGINAL
Same problem here with google-services:3.3.0, which is the last version, but according to docs version 3.2.1 should be used. I've been able to compile with the following
ext {
kotlin_version = '1.2.41'
firebaseCore = '15.0.2'
authentication = '15.1.0'
cloudFirestore = '16.0.0'
cloudStorage = '15.0.2'

classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.google.gms:google-services:3.2.1'
}

This issue seems to have been resolved by using the new google-services release (4.0.1 as of today). Below is the relevant versions that will resolve the stated issue:
In your project build.gradle files:
dependencies {
classpath 'com.android.tools.build:gradle:3.1.3'

In your app build.gradle files:

Databinding is set to true as well:

Android Studio version: 3.1.2
Thank you all for providing various ways you can get around the problem, such as the answer by #Kyle and the medium post link that shows you how to use firebase without google services.

Just downgrade your GooglePlay services dependency to 3.2.1 :)
classpath 'com.google.gms:google-services:3.2.1'

While not a great solution, I followed the recommendation from a Googler mentioned on the bug tracker.
I am using
com.google.gms:google-services:3.3.1
I have enabled databinding
`dataBinding.enabled true`
I removed the plugin reference from the app gradle script
//apply plugin: 'com.google.gms.google-services'
And followed the recommendations from this Medium post to include all of the necessary Google Service string values.
https://medium.com/#samstern_58566/how-to-use-firebase-on-android-without-the-google-services-plugin-93ecc7dc6c4
My app builds successfully and everything works as expected.

Everything worked after I added the google() maven inside the allProjects block in my project build.gradle like this:
buildscript {
repositories {
jcenter()
mavenCentral()
}
dependencies {
...
}
}
repositories {
...
}
// You need to add the google maven in this block.
allprojects {
repositories {
jcenter()
google()
}
}

Gradle sync fails - play-services-measurement-base

I have a problem on my Android project, I can't build, this is the error I have:
Failed to notify dependency resolution listener.
The library com.google.android.gms:play-services-measurement-base is being requested by various other libraries at [[15.0.2,15.0.2], [15.0.4,15.0.4]], but resolves to 15.0.4. Disable the plugin and check your dependencies tree using ./gradlew :app:dependencies.
I tried many different solution I found but the problem persists.
I have the right dependencies and repositories on gradle file on project root:
dependencies {
classpath 'com.android.tools.build:gradle:3.1.2'
classpath 'com.google.gms:google-services:4.0.1'
}
and
repositories {
jcenter()
mavenLocal()
mavenCentral()
maven {
url "https://maven.google.com"
}
}
On my app gradle I have the following dependencies:
implementation "com.google.android.gms:play-services-maps:15.0.1"
implementation "com.google.android.gms:play-services-places:15.0.1"
implementation "com.google.android.gms:play-services-gcm:15.0.1"
implementation "com.google.android.gms:play-services-location:15.0.1"
implementation "com.google.android.gms:play-services-analytics:15.0.2"
implementation "com.google.android.gms:play-services-auth:15.0.1"
implementation "com.google.android.gms:play-services-tagmanager:15.0.2"
implementation "com.google.firebase:firebase-core:16.0.0"
Some suggestions?
The solution was update the following dependencies:
implementation "com.google.android.gms:play-services-analytics:16.0.0"
implementation "com.google.android.gms:play-services-tagmanager:16.0.0"

I just added right after the apply plugin: 'com.google.gms.google-services' at the bottom of my build.gradle :
apply plugin: 'com.google.gms.google-services'
// Work around
com.google.gms.googleservices.GoogleServicesPlugin.config.disableVersionCheck = true

I had the same exact error, upgrading analytics was the key:
implementation 'com.google.android.gms:play-services-analytics:16.0.0'
I know you thought everything is updated referring to the official website, but writing 15.0.0 and looking for suggestions works better.

Update project gradle play service dependency with latest release :
classpath 'com.google.gms:google-services:4.0.1' and
Update project firebase products usage as per firebase latest release note

this shoud be on top if you use firebase libraries:
implementation "com.google.firebase:firebase-core:16.0.0"

This worked for me.this shoud be on top if you use firebase libraries:
implementation "com.google.firebase:firebase-core:15.0.0"

In my case the issue was OneSignal, which somehow broke everything down.
They even have a dedicated library for this: https://github.com/OneSignal/OneSignal-Gradle-Plugin
and the actual issue was that OneSignal was inside my app-level gradle, instead of root one.
Freaking ridiculous!

Check Answer by Bhupendra Acharya from
https://groups.google.com/forum/#!topic/firebase-talk/XbGR-YrsTTA works for you. I got the following error
The library com.google.android.gms:play-services-basement is being requested by various other libraries at [[15.0.1,15.0.1]], but resolves to 16.0.1. Disable the plugin and check your dependencies tree using ./gradlew :app:dependencies.
While using
implementation 'com.google.firebase:firebase-core:16.0.1'
And resolved by updating the version
implementation 'com.google.firebase:firebase-core:16.0.4'

My problem was that I was importing oneSignal gradle plugin but I do not import the full apply plugin: 'com.google.gms.google-services'.
To fix I just had to add the implementations I was using.

For future users: Open build.gradle files and just hover your mouse on the dependencies and a tooltip gonna show up telling your the newest version and that should solve your problem.
Beware that Firebase Documentations does not have the newest versions.

update classpath for com.google.firebase:firebase-core:16+
classpath 'com.google.gms:google-services:4.2.0'

repositories {
maven {
url "https://maven.google.com"
}
jcenter()
}
Try this one , place maven url on top inside repositories in build.gradle

Update build.gradle
buildscript {
...
dependencies {
classpath 'com.android.tools.build:gradle:3.1.2' //< update version
classpath 'com.google.gms:google-services:3.1.1' //< update version
}
}
This would help you I guess

Update the build.gradle file from the project root folder. I've tried this and it was helping.
buildscript {
repositories {
jcenter()
maven {
url 'https://maven.google.com/'
name 'Google'
}
google()
}
dependencies {
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
----
}}

Make sure you added following line in bottom of app gradle
apply plugin: 'com.google.gms.google-services'
Make sure you are using compatible google-services in project level gradle
dependencies {
classpath 'com.google.gms:google-services:4.0.1'
}
Check if you have added following dependency
implementation 'com.google.firebase:firebase-core:16.0.1'

I have answered a similar issue here. You need to keep versions of play services and firebase to latest one. Check here for links
https://stackoverflow.com/a/52696667/3333878

Try to set
classpath 'com.google.gms:google-services:3.2.1'
instead of
classpath 'com.google.gms:google-services:4.0.1'
It's helped in my case, but I don't know the cause of the error.

Failed to resolve: android.arch.lifecycle:extensions:1.0.0-alpha1 android studio 3.0

I am building a project in android studio 3.0 with android plugin 'com.android.tools.build:gradle:3.0.0-alpha1' and gradle version gradle-4.0-milestone-1-all.zip.
Used maven repo as well:
maven {
url 'https://maven.google.com'
}
Also, Using android Room persistence and lifecycle in my project. Already declared below dependencies in my app gradle file:
compile "android.arch.lifecycle:extensions:1.0.0-alpha1"
compile "android.arch.persistence.room:runtime:1.0.0-alpha1"
annotationProcessor "android.arch.lifecycle:compiler:1.0.0-alpha1"
annotationProcessor "android.arch.persistence.room:compiler:1.0.0-alpha1"
When Sync and build the project it's showing below error:
Failed to resolve: android.arch.lifecycle:extensions:1.0.0-alpha1
Am I missing something or any other solution for this issue.

I have fixed the issue by updating my app build.gradle file like below:
// 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:3.0.0-alpha2'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
maven { url 'https://maven.google.com' }
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
Actually had to remove the maven repository from buildscript repositories and added to allprojects repositories as shown above. Also you can keep the maven repository at both places but must include in allprojects repositories to fix the issue.

Add in app/gradle file
compile "android.arch.lifecycle:extensions:1.0.0-alpha4"
compile "android.arch.persistence.room:runtime:1.0.0-alpha4"
annotationProcessor "android.arch.lifecycle:compiler:1.0.0-alpha4"
annotationProcessor "android.arch.persistence.room:compiler:1.0.0-alpha4"
add maven to project based gradle
allprojects {
repositories {
jcenter()
maven { url 'https://maven.google.com' }
}
}
it will compile easily

am find solution work with me Room
Dependencies for Room, including testing Room migrations and Room RxJava
dependencies {
def room_version = "1.1.1"
implementation "android.arch.persistence.room:runtime:$room_version"
annotationProcessor "android.arch.persistence.room:compiler:$room_version" // use kapt for Kotlin
// optional - RxJava support for Room
implementation "android.arch.persistence.room:rxjava2:$room_version"
// optional - Guava support for Room, including Optional and ListenableFuture
implementation "android.arch.persistence.room:guava:$room_version"
// Test helpers
testImplementation "android.arch.persistence.room:testing:$room_version"
}
as the document says: https://developer.android.com/topic/libraries/architecture/adding-components

you can change "https://maven.google.com" to "https://dl.google.com/dl/android/maven2/" to solve the problem.

You require latest gradle version 'com.android.tools.build:gradle:3.0.0-alpha2' and Studio Version 3.0+ to use Room

Just add maven { url 'https://maven.google.com' } to your project gradle

open preference for mac or you can open setting for windows then search proxy setting inside the open window then unchecked proxy authentication it will work
