Not able to use kotlin library

I am trying to use this library for my app but as it is made in kotlin I am facing the problem . I downloaded the module of this library and imported this module in the project but in the initial state i am gettin kotlin plugin not found so i changed the gradel as this
apply plugin: 'com.android.library'
apply plugin: 'kotlin-android'
android {
compileSdkVersion 26
buildToolsVersion "26.0.2"
defaultConfig {
minSdkVersion 17
targetSdkVersion 26
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
sourceSets {
main.java.srcDirs += 'src/main/kotlin'
}
resourcePrefix "yal_ms_"
}
buidscript {
ext.kotlin_version = '1.0.1-2'
repositories {
jcenter()
mavenCentral()
}
dependencies {
classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.0.1-2'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile "com.android.support:appcompat-v7:26.1.0"
compile "com.android.support:recyclerview-v7:26.1.0"
compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
}
repositories {
mavenCentral()
jcenter()
}
I am trying to use the kotlin library for the first time and I dont know any thing much about kotlin any advice how to use this library will be helpful .

Try Importing this library by gradle
Add maven { url "https://jitpack.io" } to the repositories of project gradle. So it will be like this
build.gradle(Project)
buildscript {
ext.kotlin_version = '1.1.60'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
maven { url "https://jitpack.io" }
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
and add compile 'com.github.yalantis:multi-selection:v0.1' to dependencies in build.gradle(app)
This may create Manifest Merge Conflicts error while building project to remove that add tools:replace="android:label" under <application> tag in Manifest

Getting an error when using com.google.android.gms:play-services-maps:11.2.0 in my application

I am trying to create a simple Android application. I have the latest version of Android Studio and i think both my gradle build files are correct.
I have placed
implementation 'com.google.android.gms:play-services-maps:11.2.0'
in app gradle dependencies.
Due to this I get the following error:
Unable to resolve dependency for ':app#debug/compileClasspath': Could not resolve com.google.android.gms:play-services-maps:11.2.0.
I have looked at various links and tried out proposed solutions but none have worked for me.
Below are both my gradle build files.
project build.gradle:
//Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
classpath 'com.google.gms:google-services:3.0.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
maven { url "https://repo.situm.es/artifactory/libs-release-local" }
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
app build.gradle:

//androidTestImplementation 'com.android.support.test.espresso:espresso-

}
//apply plugin: 'com.google.gms.google-services'
Hope you can help.
Thanks,

try this i found:
Failed to resolve com.google.android.gms play-services-auth:11.2.0
Add maven to your root level build.gradle file
allprojects {
repositories {
jcenter()
maven {
url "https://maven.google.com"
}
}
}
This maven repo is required starting from 11.2.0.
Or add google() repository to your "build.gradle" file. This gradle method is equivalent to
maven { url "https://maven.google.com" }.
repositories {
jcenter()
google()
}

Gradle DSL method not found: 'compile()' using Twitter sdk

I now there some other guys, which asked for this kind of problem, but all this solutions doesn't worked for me. I only added the twitter sdk's an nothing else in the Project.
Please help me
Android gradle build Error:(9, 0) Gradle DSL method not found:
'compile()'.
Getting Error "Gradle DSL method not found: 'compile()'" when Syncing Build.Gradle
My build.gradle code is here
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
compile 'com.twitter.sdk.android:twitter:3.1.1'
compile 'com.twitter.sdk.android:twitter-mopub:3.1.1'
compile 'com.twitter.sdk.android:twitter-core:3.1.1'
compile 'com.twitter.sdk.android:tweet-ui:3.1.1'
compile 'com.twitter.sdk.android:tweet-composer:3.1.1'
compile 'com.twitter.sdk.android:twitter-mopub:3.1.1'
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

I guess you mess between your root build.gradle and application's build.gradle.
As minimum you should remove classpath 'com.android.tools.build:gradle:2.3.3' from dependencies { ... } of your application’s Gradle config (usually app/build.gradle).
Then you should check your root build.gradle. It should look like:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
Then you will need to add the following dependencies to your application’s Gradle config (usually app/build.gradle) as wrote in the official docs
dependencies {
compile 'com.twitter.sdk.android:twitter:3.1.1'
compile 'com.twitter.sdk.android:twitter-mopub:3.1.1'
}

First build.gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "25.0.3"
defaultConfig {
applicationId "com.twitter.ratz.william.test"
minSdkVersion 19
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:26.+'
compile 'com.android.support.constraint:constraint-layout:1.0.0-beta3'
compile 'com.twitter.sdk.android:twitter:3.1.1'
compile 'com.twitter.sdk.android:twitter-mopub:3.1.1'
testCompile 'junit:junit:4.12'
}
Second build.gradle
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

Kotlin version 1.1.4-eap-77 is not working

I started a new app in Kotlin, but when Android Studio finished to build the new project, etc.. is says that cand download the correct version of Kotlin:
Here is the build gradle:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
ext.kotlin_version = '1.1.4-eap-77'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0-beta2'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
and the app gradle:
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
android {
compileSdkVersion 26
buildToolsVersion "26.0.1"
defaultConfig {
applicationId "com.xxxxxx.xxxxxx"
minSdkVersion 20
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
implementation 'com.android.support:appcompat-v7:26.0.1'
implementation 'com.android.support:design:26.0.1'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.0'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.0'
}
How can I fix it to allow download the correct version?

To use a EAP version of the kotlin plugin you have to add the repo in the buildscript block
maven {
url 'https://dl.bintray.com/kotlin/kotlin-eap-1.1'
}
Something like:
buildscript {
ext.kotlin_version = '1.1.4-eap-77'
repositories {
google()
jcenter()
maven {
url 'https://dl.bintray.com/kotlin/kotlin-eap-1.1'
}
}
//...
}
Also you should add the same maven repo to repository block to download the kotlin dependencies.
Something like:
repositories {
google()
jcenter()
maven {
url 'https://dl.bintray.com/kotlin/kotlin-eap-1.1'
}
}
You can find more info here.

Gradle DSL method not found: 'classpath()'

The project 'FeedBack' 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).
Fix plugin version and sync projectThe project 'FeedBack' may be using a version of Gradle that does not contain the method.

You have to insert classpath dependencies inside buildscript block.
buildscript {
repositories {
jcenter()
maven { url 'https://maven.fabric.io/public' }
}
// move it here
dependencies {
classpath 'com.android.tools.build:gradle:2.1.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
// The Fabric Gradle plugin uses an open ended version to react
// quickly to Android tooling updates
classpath 'io.fabric.tools:gradle:1.+'
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
