Gradle Project Sync Failing

My Project Sync is failing with the below errors -

}
Any help in this regard would be appreciated!!!
How do I resolve this??
I have tried Invalidate Caches/Restart option and also tried to rebuild the project but it didn't help..

It seems that Exoplayer-core and Exoplayer-dash are broken since today
https://github.com/google/ExoPlayer/issues/5225

By this Gradle configuration it works fine :
android {
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
compileSdkVersion 27
defaultConfig {
...
targetSdkVersion 27
...
}
}
ext {
exoplayer_version = '2.9+'
}
dependencies {
...
//exoplayer
implementation ('com.google.android.exoplayer:exoplayer-core:' + exoplayer_version)
implementation ('com.google.android.exoplayer:exoplayer-dash:' + exoplayer_version)
implementation ('com.google.android.exoplayer:exoplayer-hls:' + exoplayer_version)
implementation ('com.google.android.exoplayer:exoplayer-smoothstreaming:' + exoplayer_version)
implementation ('com.google.android.exoplayer:exoplayer-ui:' + exoplayer_version)
implementation ('com.google.android.exoplayer:exoplayer:' + exoplayer_version)

So for sure if you didn't include exoplayer library in your
build.gradle, your project won't synch.
UPDATE:
Okay, sorry, now I got the problem you all using com.facebook.android:audience-network-sdk have experienced these days, and why in your build.gradle file there is not exoplayer dependency set.
Using com.facebook.android:audience-network-sdk that depends on exoplayer, if you didn't explicitly specify exoplayer-core and exoplayer-dash, gradle try to download the necessary dependency as for docs.
So, as #laylakn pointed out (upvoted for that) there where an issue between repository mirroring between bintray and jcenter.
So, specifically to your problem, since you have told me that you have tried adding the libraries and synch without success, that's because the version of exoplayer you are looking for (r2.4.2) is in the spring plugin repository.
So you should add it as your maven repo (because of the mirroring error of repositories stated before):
maven {
url "https://repo.spring.io/plugins-release/"
}
Or as explain on main GitHub repo, just pointing directly to bintray.
maven {
url 'https://google.bintray.com/exoplayer/'
}
and you should synch your project adding this two libraries:
implementation 'com.google.android.exoplayer:exoplayer:r2.4.2'
implementation 'com.google.android.exoplayer:exoplayer-smoothstreaming:r2.4.4'
So now I'm glad to here from you that the mirroring problem has been resolved and are you able to sync right now, without doing any changes to your build.gradle files.
I've left and updated my answer to better explain this situation.
Also some other famous repo take precautions: [-:

Error: cannot access zzbgl

I am developing an application and I am getting the following error:
error: cannot access zzbgl
class file for com.google.android.gms.internal.zzbgl not found
I know there's a question here in StackOverflow with the same error that I'm getting posted 4 days ago but the answer did not help in my case. (I am talking about this one)
The error appeared just right after setting Firebase Analytics in my project.

I hope someone can see the error and solve this, thank you so much in advance.
If you need any more information in order to solve this, please let me know.

The Google API Release Notes indicate that support for the combined play-services library ended in April 2018:
Starting with 15.0.0, there will no longer be a play-services alias target to pull in all Google Play services components. This has been recommended against for some time.
You can no longer specify a single dependency on the combined Google Play services target like this anymore:
implementation 'com.google.android.gms:play-services:12.0.1'.
When this was supported with previous versions, it pulled in ALL the Google Play libs way more than you need. See the list of APIs in Table 1 of the Setup Guide and include only the specific ones your app uses.
A check of the Google Maven Repository confirms that version 12.0.1 was the last version of the combined play-services target.
So please delete the above implementation and use only:
implementation "com.google.android.gms:play-services-base:15.0.1"
If you are also using other play services, please add them as separate dependencies.

I think your main reason for the error is that you are using 2 different versions for play services libraries
implementation 'com.google.android.gms:play-services:12.0.1'
Here it is 12.0.1
implementation "com.google.android.gms:play-services-base:15.0.1"
While here it is 15.0.1.
Try to use same version of related libraries everywhere.

Just simply you need to change a Dependency because 12.0.1 is no more
implementation 'com.google.android.gms:play-services:12.0.1'
To
implementation 'com.google.android.gms:play-services-base:15.0.1'
And press sync Gradle
Hope this may help you

updates the version of all dependencies.
Generally, this error will happen if you are working with several new and old dependencies.

Firebase libraries must use the exact version error

I want to use google cloud messaging for push notification to android application. I read bellow document and set firebase to my application. My gradle build successfully but in implementation 'com.google.firebase:firebase-core:16.0.1' part, I get following error:
All gms/firebase libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 17.1.0, 16.2.0, 16.1.1, 16.0.1, 16.0.0, 15.0.1. Examples include com.google.firebase:firebase-messaging:17.1.0 and com.google.firebase:firebase-iid:16.2.0 less... (Ctrl+F1)
There are some combinations of libraries, or tools and libraries, that are incompatible, or can lead to bugs. One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or in particular, a version lower than your targetSdkVersion.)

What is the problem and how can I solve it?

You have added 2 different versions of firebase library.
implementation 'com.google.firebase:firebase-core:16.0.1'
implementation 'com.google.firebase:firebase-messaging:17.1.0'
Please change it to same version i.e, 15.0.2
I am using this version only and did not face a problem until now. If you want you can probably use 16.0.1 for messaging also. There might be a possibility that google has not released version 17 for firebase-core.

Updating firebase library to 16.0.0 raises google play services dependency issue

My project was working fine until one day, because of no reason (I didn't change anything), gradle started giving this strange error:
Program type already present: com.google.android.gms.internal.measurement.zzabo

I searched and found this answer on stackoverflow. Which says that this issue might be related to firebase dependency version and google-services plugin. So i updated google-services plugin version to 4.0.0 and firebase to its latest version 16.0.0. And as one could expect from gradle, it gave another error which seems to be related to firebase version 16.0.0.
Whenever i change firebase version to 16.0.0, apparently it tries to automatically upgrade google play services dependencies to 16.0.0 too. Which doesn't EVEN exist! It raises following gradle error:
Failed to resolve: com.google.android.gms:play-services-maps:16.0.0

I have tried to force version of gms libraries using resolutionStrategy but to no avail. What should i do? What am I doing wrong?
NOTE: I didn't change play services libraries version explicitly, gradle seems to do it because of firebase.
EDIT: This problem can be solved by the solution given in this question, but still its not duplicate because in my case onesignal plugin was updating only gms libraries version and not firebase version. So anybody facing this problem won't search for keywords used in this question.

I believe you have run into the same issues as the poster of https://stackoverflow.com/a/50516114/7070704 with the same resolution.
Basically, the com.onesignal.androidsdk.onesignal-gradle-plugin plugin is forcing an uplift on your dependencies onto something which does not exist.

Could not find com.google.firebase:firebase-core:9.0.0?

In my app, I am trying to use gcm services, but I cannot even get gradle to compile. I keep getting the message that I am missing 'firebase core' though I have no idea how to install this.
This is my top-level gradle file:

In your module Gradle file (usually the app/build.gradle), add the apply plugin(apply plugin: 'com.google.gms.google-services') line at the bottom of the file to enable the Gradle plugin.
You should also add the dependencies for the Firebase com.google.firebase:firebase-core and com.google.firebase:firebase-messaging SDK's:
apply plugin: 'com.android.application'
android {
// ...
}
dependencies {
// ...
compile 'com.google.firebase:firebase-core:10.2.1'
compile 'com.google.firebase:firebase-messaging:10.2.1'
}
// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'
Make sure you have the latest version of 'Google Play services' and 'Google Repository' installed while using Firebase.
Please follow below steps to install:
Open Android studio
Go to the Menu bar > Tools > Android > SDK Manager
Click on Tab > SDK Tools
Check and install 'Google Play Services' and 'Google Repository'
Click on Apply and wait for the download
Finally, Sync and build your project again.

You want to add push notifications in your app ?
use firebase instead of GCM. it is enhanced version of GCM.
You need following dependencies for firebase push notifications.
compile 'com.google.firebase:firebase-messaging:9.0.1'
compile 'com.google.android.gms:play-services-gcm:9.0.1'
for further info visit http://codingaffairs.blogspot.com/2016/06/firebase-cloud-messaging-push.html

I had the same problem with com.google.firebase:firebase-core:11.8.0 and it worked after moving the google() repository above jcenter().
In between I used Build -> Clean Project.
./build.gradle
buildscript {
repositories {
google() // <- now on top!
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
classpath 'com.google.gms:google-services:3.1.1'
}
}
allprojects {
repositories {
google() // <- now on top!
jcenter()
}
}

If you want to add the firebase core, you can add
compile 'com.google.firebase:firebase-core:9.0.0'
under dependencies tag in your module-level gradle file.
If you still can't resolve it, maybe you need to update the SDK to get the Google Play Services rev 30 and Google Repository rev 26 first. See here for the detail.

In your android/build.gradle in your repositories section, try moving google() ABOVE jcenter().
