Multiple dex files define Lcom/getkeepsafe/relinker/SystemLibraryLoader;

I am facing this problem when am trying to build my project -> Multiple dex files define Lcom/getkeepsafe/relinker/SystemLibraryLoader;
I have tried to clean the .gradle, deleting the build folder and reinstalling dependencies but its still not working.
Here is my build.gradle:moduleapp

Please advice what i can do to solve this proplem

Add this string inside dependecies{} in build.gradle:moduleapp
dependencies {
compile 'com.getkeepsafe.relinker:relinker:1.3.1' //this string
}
it seems that you are using a very old ready-made script, I advise you to do everything by yourself.
I recommend you to use 'implement' or 'api' instead of 'compile'
Also don't use
compile 'pl.droidsonroids.gif:android-gif-drawable:1.2.+'
always use a specific version to avoid other 'Multiple dex files define' issues, for example.
compile 'pl.droidsonroids.gif:android-gif-drawable:1.2.17'
don't forget to rebuild the project by following step in toolbar-menu: Build -> Rebuild Project.

Failed to resolve: support-v4

I am getting the error Failed to resolve: support-v4 I've tried loads of solutions online but none work. This started happening after I migrated to androidX and after I updated Android Studio.
I've tried changing version around. Im not quite sure if there is any conflicting library's or if that is even an problem. Please help , I'm really struggling.
Thank you in advance

Update:
I have also tried Clearing the project. When I do so the following error comes up.
Could not find support-v4.aar (androidx.legacy:legacy-support-v4:1.0.0).Searched in the following locations:
https://dl.google.com/dl/android/maven2/androidx/legacy/legacy-support-v4/1.0.0/support-v4-1.0.0.aar

you might be missing a dependency:
dependencies {
api "androidx.legacy:legacy-support-v4:1.0.0"
}
Firebase and Google Services are also rather outdated versions... with androidx you should get rid of versions = [supportLib:"27.0.2"] and those 28.0.0 versions. as a migration example:
dependencies {
// compile "com.android.support:support-compat:28.0.0"
api "androidx.core:core:1.0.0"
// compile 'com.android.support:appcompat-v7:28.0.0'
api "androidx.appcompat:appcompat:1.0.0"
// compile 'com.android.support:recyclerview-v7:28.0.0'

Firebase API initialization failure.java.lang.reflect.InvocationTargetException

I have integrated the FCM Database in my Android project. I used it for chat application. Now I need to implement the cloud message(Push notification) using FireBase. After I implement the FCM, I got an error-
Firebase API initialization failure. java.lang.reflect.InvocationTargetException
I am sending the gradle script please have a look.

To solve this, you need to add the following line of code:
apply plugin: 'com.google.gms.google-services'
As the last line in your build.gradle (Project: ProjectName) file.
And if you are using also authentication, please also this line of code:
compile 'com.google.android.gms:play-services-auth:10.0.1'
I also strongly recommend you to use the latest versions for your Firebase dependencies. The latest version is now: 11.8.0.
The last version for Google Play Services is:
classpath 'com.google.gms:google-services:3.2.0'

Multiple dex files define Lcom/google/android/gms/common/AccountPicker;

I'm getting

Can't see the reason at the moment.

Problem
Same com.google.android.gms:play-services
Solutions
Delete google-play-services from build.gradle & Local lib folder .
compile files('libs/google-play-services.jar')
After that Clean-Rebuild-Run.

Try multiDexEnabled true in app build.gradle

You are adding the same class twice.
Remove this line:
compile files('libs/google-play-services.jar')
Also you have to delete the file libs/google-play-services.jar since you are using compile fileTree(include: ['*.jar'], dir: 'libs')
