update repositories. No more maven.fabric.io!

[spatial25]

I am using linux but not ubuntu and was able to get a successful build. I am sharing the files. Changes were with updating the repository because maven.fabric.io no longer works.
All changes were in the mobile, shared, wear build.gradle files, and :mobile/utils/MainActivity.kt.

Files Mentioned

I'm using android studio bumblebee.

In /wear/build.gradle:
[Might be better to use the 1.3.72, I was having problems with 1.5.30. You could probably mess with different repositories to update kotlin to 1.5.30.]

buildscript {} update ext.kotlin_version to "1.3.72"

New repository are:
maven { url 'https://mvnrepository.com/artifact' }
maven { url 'https://repo1.maven.org/maven2' }

These are the dependencies I put:
dependencies {
classpath 'com.android.tools.build:gradle:4.0.2'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version"
classpath 'com.android.tools.build:gradle:1.3.1'
classpath 'com.google.gms:google-services:4.3.10'
classpath 'com.google.firebase:firebase-crashlytics-gradle:2.7.1'
}
allprojects {
repositories {
maven { url 'https://mvnrepository.com/artifact' }
google()
jcenter() [jcenter no longer is supported but keep on because it prevents errors on MainActivity.kt]
Add mavenCentral()
}

At the very end:
ext {
minSdkVersion = 19
targetSdkVersion = 29
compileSdkVersion = 29
buildToolsVersion = "27.0.3"
kotlinVersion = "1.3.72"
supportVersion = "28.0.0"
}

/shared/build.gradle:
add apply plugin: 'org.jetbrains.kotlin.kapt'

in /mobile/build.gradle:
apply plugin: 'com.android.application'
//apply plugin: 'io.fabric'
apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.google.firebase.crashlytics'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
add apply plugin: 'org.jetbrains.kotlin.kapt' [maybe redundant or vice versa]

repositories {
google()
jcenter()
Add mavenCentral()
maven { url 'https://mvnrepository.com/artifact' }
}

[remove crashlytics and add two implementations below]
//implementation('com.crashlytics.sdk.android:crashlytics:2.10.1@aar') {
// transitive = true
Add
implementation 'com.google.firebase:firebase-crashlytics:18.2.1'
implementation 'com.google.firebase:firebase-analytics:19.0.1'

In the MainActivity.kt:
Remove import com.crashlytics.sdk.android and
import io.fabric.sdk.android.Fabric

Add import com.google.firebase.crashlytics.FirebaseCrashlytics;

Remove Fabric.with(this, Crashlytics())
and Add FirebaseCrashlytics.getInstance().setCrashlyticsCollectionEnabled(true)

Those are the major changes and I was able to get a successful build with no errors with only 5 warnings on new mapping. There are small upgrades to numbers that I didn't add but will be on the files.
