Errors when adding firebase to a project that calls Microsoft graph

I am trying to add firebase to a existing application which involves adding:
classpath 'com.google.gms:google-services:4.3.3'

as a plugin to the app level build.gradle.

I had the same problem. I was able to solve it by using classpath 'com.google.gms:google-services:4.0.0' instead of classpath 'com.google.gms:google-services:4.3.3'. Build this to see another type of error. Then do invalidate cache and restart on Android studio from the File menu. Then on restart, your build should be successful. You might also need to use 'com.google.firebase:firebase-analytics:16.0.0' instead of the current version

bintray: Unable to upload files: Maven group, artifact or version defined in the pom file do not match

I'm trying to create a maven library using Android Studio and bintray but I can't get it working. When I try to upload the lib using gradle bintrayUpload I allways get the following error:
Could not upload to 'https://api.bintray.com/content/company/maven/company-simplename-lib/simplename/company-simplename-lib/lib/0.0.1/lib-0.0.1.pom': HTTP/1.1 400 Bad Request [message:Unable to upload files: Maven group, artifact or version defined in the pom file do not match the file path 'company-simplename-lib/lib/0.0.1/lib-0.0.1.pom']
This happens when I try to follow the example bintray has in their github repo.
I have changed my library build.gradle (not the root) to the following:
buildscript {
repositories {
jcenter()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.3.0'

Is someone able to see what I'm doing wrong? Becasue I can't and I can't find any good documentation about this either.

Please go through below blog , it clearly explain everything.
http://inthecheesefactory.com/blog/how-to-upload-library-to-jcenter-maven-central-as-dependency/en
If you still face issue of uploading pom file then make sure
libraryName , artifact and module name should be same.

I got it working by removing the install part from the gradle file so it looks like this:
buildscript {
repositories {
jcenter()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.3.0'
classpath 'com.github.dcendents:android-maven-gradle-plugin:1.3'

Uploading an Android library with gradle and BinTray. Package after upload is always "com.xxx.xxx.app.vers" instead of "com.xxx.xxx.LibraryName.vers"

I want to upload a library to Maven/BinTray through gradle. After a long period of trial and error, I managed to upload it.
As you can see, the resulting package is "app" instead of "libraryName".
Here is my build.gradle (top level)
buildscript {
repositories {
jcenter()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.2.3'
classpath 'org.codehaus.groovy:groovy-backports-compat23:2.3.5'
classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.0'
classpath 'com.github.dcendents:android-maven-gradle-plugin:1.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}

apply from: 'https://raw.githubusercontent.com/smasoumi/Bintray/master/install.gradle'
apply from: 'https://raw.githubusercontent.com/smasoumi/Bintray/master/bintray.gradle'
Here is my settings.gradle:
include ':app'
rootProject.name = 'libraryName'
Things I have tried:
Setting the rootProject.name ="..." as specified in the android-maven-gradle documentation. Did not work.
Adding "artifact" in the ext {} - Did not work.
Setting the artifact name same as rootProject.name. Did not work.
Has anyone encountered this problem and can help me? Thank you!

How to upload module to JCenter using gradle bintray plugin?

I am sorry if I am being too stupid but I just can't make it work... I have an Android Module Project in AS that I want to upload to JCenter - using gradle bintray plugin from JFrog. I follow this tutorial in order to create the repository on bintray and I ended up with the following build.gradle for the module:
apply plugin: 'com.android.library'
apply plugin: 'com.jfrog.bintray'
apply plugin: 'com.github.dcendents.android-maven'
Properties properties = new Properties()
properties.load(project.rootProject.file('local.properties').newDataInputStream())
bintray {
user = properties.getProperty('bintray.user')
key = properties.getProperty('bintray.apikey')
configurations = ['published', 'archives']
dryRun = false
publish = true
pkg {
repo = 'maven'
name = 'custom-searchable'
desc = 'This repository contains a library that aims to provide a custom searchable interface for android applications'
websiteUrl = 'https://github.com/...'
issueTrackerUrl = 'https://github.com/.../issues'
vcsUrl = 'https://github.com/....git'
licenses = ['The Apache Software License, Version 2.0']
labels = ['android', 'searchable', 'interface', 'layout']
publicDownloadNumbers = true
version {

desc = 'Bintray integration test'
vcsTag = '1.0'
}
}
}
ext {
bintrayRepo = 'maven'
bintrayName = 'custom-searchable'
publishedGroupId = 'br.com.edsilfer'
libraryName = 'CustomSearchable'
artifact = 'custom-searchable'
libraryDescription = 'This repository contains a library that aims to provide a custom searchable interface for android applications'
siteUrl = 'https://github.com/...'
gitUrl = 'https://github.com/....git'
libraryVersion = '1.0'

allLicenses = ["Apache-2.0"]
}
android {
compileSdkVersion 22
buildToolsVersion "22.0.1"
defaultConfig {
minSdkVersion 22

versionCode 1

}

And this one for the project:
// Top-level build file where you can add configuration options common to all sub-projects/modules.

}

classpath 'com.github.dcendents:android-maven-gradle-plugin:1.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
After running the task gradle bintrayUpload (it finishes sucessfully) my repository in bintray looks like that:
And when you open the unspecified folder you'll find this:
So questions!
Why version is being upload like unspecifiend?
I can't compile my project with the given group id:artifact:version, when trying to build it on AS it says that it fails to resolve the path to the artifact.
Any help will be appreciated!

You are using the standard configuration provided by the gradle plugin, which do not specify library version.
I'm using the publication instead:
...
apply plugin: 'com.jfrog.bintray'
apply plugin: 'maven-publish'
...
bintray {
...
publications = ['Publication']
pkg {
...
}
}
publishing {
publications {
Publication(MavenPublication) {
artifact jar
groupId 'com.lib'
artifactId 'help-er'
version '0.1'
}
}
}
If you want to use configurations check this question: Publish on bintray using the gradle-bintray-plugin
