ERROR: Unable to resolve dependency for ':app#debug/compileClasspath': Could not resolve com.google.android.gms:play-services-base

As you can see here are the errors I'm getting when I'm trying to sync my project I'm getting this issue again and again. Gradle is in Online mode. I also tried offline mode but I found the same issue.
I also tried so many methods but still, I can't able to solve this problem.

This is the errors I'm getting knowing that min-sdk is set to 24 and I only in the gradle and I have removed it from both manifests (app & pdfLibrary):
I have tried suggestion from other SO questions, but nothing worked.

edit minSdkVersion to 21 instead of 24 in pdfLibrary gradle

In the allprojects block you have to add the google() maven repo.
allprojects {
repositories {

maven { url 'https://maven.fabric.io/public' }

There is an issue in your dependency version

Replace with

Place this code:
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
mavenCentral()
maven { url 'https://jitpack.io' }
}
}
in the settings.gradle

}
Also in gradle-wrapper.properties add this line or change if already exist with other value:
distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.1-all.zip

Just remove :15.0.0 from the firebase implementation!
The implementation should be like:
implementation 'com.google.firebase:firebase-auth:16.1.0'
Else every thing seems fine!

AndroidStudio - Program type already present: com.google.android.gms.location.places.zza

First : Let me explain the situation , i have an sdk works with google Api and implementing a lot of dependencies. then i implement the lib into my new app which is also implements dependencies. everything goes fine until i try to run the app.
When i run (on device) my project I get the following error message:
Error: Program type already present: com.google.android.gms.location.places.zza
With the following stacktrace in the Gradle Log (not all of it)

I Added this dependency and it worked fine !
implementation 'com.google.android.gms:play-services-places:16.0.0'

already present is never being caused by a missing dependency ...
implementation ("br.com.inngage.sdk:inngage-lib:2.2.0") {
exclude group: "com.google.android.gms", module: "play-services"
}
just see MavenCentral, it adds a few duplicate & outdated dependencies.

the problem is that you have a duplicated dependency with different version if you can find the implementation that needs com.google.android.gms.location you can put under it exclude com.google.android.gms or simply in build.gradle module:project
ext {
googlePlayServicesVersion = "16.0.0"
}
