Gradle DSL method not found: 'dataBinding()'

I am new to Android. Here I am trying to add data binding to my android app for that I enabled data binding to true in-app level gradle file but the problem is it's not syncing it gives some error like this.
Gradle DSL method not found: 'dataBinding()'
Possible causes:
The project 'TriviaApp' may be using a version of the Android Gradle plug-in that does not contain the method (e.g. 'testCompile' was added in 1.1.0).
Upgrade plugin to version 3.4.1 and sync project
The project 'TriviaApp' may be using a version of Gradle that does not contain the method.
Open Gradle wrapper file
The build file may be missing a Gradle plugin.
Apply Gradle plugin
this is My app level gradle file code
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.example.triviaapp"
minSdkVersion 19
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
dataBinding(

)
}

implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"

testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
Can anyone please help me to figure out what am I doing wrong and help me to fix this.

You should use
dataBinding {
enabled = true
}
Make sure, your build.gradle is
dependencies {
classpath 'com.android.tools.build:gradle:3.4.1'
}
allprojects {
repositories {
jcenter()
}
}

OSM Android dependecies failed to resolve

I'm currently trying to implement OSMDroid in to my project, but doing it has shown in the OSMDroid tutorial (http://osmdroid.github.io/osmdroid/index.html) does not seem to be working.
When I try to sync the Gradle project I get the following message:
Failed to resolve: osmdroid-android
And I have here the full build.gradle(Module: app):
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.example.massas.emergency_numbers_pi"
minSdkVersion 23
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation 'org.osmdroid:osmdroid-android:6.0.0-SNAPSHOT'
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
Am I doing something wrong or is the dependencie just outdated? Should I insert the dependencies in the project build.gradle?
I'm new to android dev, so please bear with me! Thanks

1) Make sure you have added the repository. You need maven central for stable releases and sonatype for snapshot. Instructions for that are included in the documentation but for the sake of this response:
Current stable:
repositories {
mavenCentral()
}
dependencies {
implementation 'org.osmdroid:osmdroid-android:6.0.1'
}
Current snapshot:
repositories {
mavenCentral()
maven{
url 'https://oss.sonatype.org/content/repositories/snapshots/'
name 'OSS-Sonatype'
}
}
dependencies {
implementation 'org.osmdroid:osmdroid-android:6.0.2-SNAPSHOT'
}
Note: you can also add repositories to your root gradle file to the allprojects section.
2) You should use the stable version (6.0.1 at the time of writing) uless you have a specific reason to use snapshot.

By your version of gradle plugin I assume you are using not the latest Android studio, but 3.1.x.
Try to use 3.2.5 beta from Canary (Beta) channel. It might help

Unable to resolve dependency for :app#debugAndroidTest/compileClasspath': Could not resolve com.android.support:design:26.1.0 This issue usually happens when the Android Studio is not able to download that dependency.That can be due to many reasons like this Or like in my case where the Maven2 and jcenter repositories are blocked in Company. So what can you do is like check this folder
Android-sdk\extras\android\m2repository\com\android\support\appcompat-v7
and check which all versions are available to you in the SDK, use either one of those versions ,So instead of downloading from repository studio will take that lib from SDK.

Try to add your Google maven repo. it works for me.##
repositories {
jcenter()
maven {
url "https://maven.google.com"
}
}
