android build gradle error (android 3.1.3)

I reinstalled my android studio and thereafter i am getting error while building gradle.
I did every change that can help in building gradle but then also it showed error as "configure build" error.
so kindly help me so that i can start my android programming.
gradle version - 4.4
android plugin version - 3.1.3`
i have changed google() to maven() but nothing happened.
//build.gradle file
// Top-level build file where you can add configuration options common to all
sub-projects/modules.
buildscript {
repositories {
google()
jcenter { url 'http://jcenter.bintray.com' }
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.3'
// 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
}

kotlin runtime below plugin version

My android studio is sending me this warning:
Outdated Kotlin Runtime
Your version of Kotlin runtime in 'Gradle:
org.jetbrains.kotlin:kotlin-stdlib:1.2.10#jar' library is
1.2.10-release-109 (1.2.10), while plugin version is 1.2.41-release-Studio3.1-1.
Runtime library should be updated to avoid compatibility problems.
This warning appear every time I open the project and it finishes the Gradle sync How do I update the Kotlin runtime?
I have found questions about it, but all of them the problema was that the plugin version that was below runtime and needed to update the plugin version on the build.gradle file, but my case is the opposite. My build.gradle is like this:
buildscript {
ext.kotlin_version = '1.2.41'
ext.anko_version='0.10.5'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.2'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.google.gms:google-services:3.2.0'
}
}
allprojects {
repositories {
google()
jcenter()
maven { url 'https://jitpack.io' }
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
If I try to downgrade the plugin to 1.2.10, them the IDE gives a warning that the plugin is outdated.

Excecution failed for task ':app:preDebugAndroidTestBuild'

I am completely new to android and kotlin programming. I just started learning android since yesterday. I have successfully created a project but it doesn't show me xml editor.
Error:Execution failed for task ':app:preDebugAndroidTestBuild'.
Conflict with dependency 'com.android.support:support-annotations' in project ':app'. Resolved versions for app (26.1.0) and test app (27.1.1) differ. See https://d.android.com/r/tools/test-apk-dependency-conflicts.html for details.
build.gradle
buildscript {
ext.kotlin_version = '1.1.51'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
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
}
Any idea to solve this problem

configurations.all {
resolutionStrategy {
force 'com.android.support:support-annotations:26.1.0'
}
}
Add the above line in your app.gradle file before dependencies block & replace compile to implementation.

In Android Studio , click on Terminal and execute this command.
gradlew app:dependencies
and then search for com.android.support:support-annotations.
Then in your app level gradle file , exculude the com.android.support:support-annotations dependency from the dependency which has the older version i.e 26.1.0. To learn how to exuclude go here.

Gradle project sync failed in android studio 3.1

my gradle.build contains
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.0'
// 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 upon syncing project with gradle files is showing error as connection refused:connect .
There is a problem with Apply script build.gradle
Not able to resolve dependencies of classpath
Log file showing the below error
Caused by: org.gradle.internal.resource.transport.http.HttpRequestException: Could not GET 'https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/3.1.0/gradle-3.1.0.pom'.
at org.gradle.internal.resource.transport.http.HttpClientHelper.performRequest(HttpClientHelper.java:96)

Try using invalidate caches and restart in File Menu. Most of the time it works when studio have a new update.

Goto "File > Project Structure > SDK Location" menu and
Check "Use embedded JDK(recommended)".
It may be your JDK version problem.

Could not find com.android.tools.build:gradle:4.4

I just migrated gradle from 3.0.1 to 4.4. Now Android Studio showing gradle build failed showing below errors.
Caused by: org.gradle.internal.resolve.ModuleVersionNotFoundException: Could not find com.android.tools.build:gradle:4.4.
Searched in the following locations:
https://jcenter.bintray.com/com/android/tools/build/gradle/4.4/gradle-4.4.pom
https://jcenter.bintray.com/com/android/tools/build/gradle/4.4/gradle-4.4.jar https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/4.4/gradle-4.4.pom https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/4.4/gradle-4.4.jar
Project level build.gradle file is following below
buildscript {
repositories {
jcenter()
google()
}
dependencies {
//classpath 'com.android.tools.build:gradle:3.0.1'
//replaced by 4.4 below
classpath 'com.android.tools.build:gradle:4.4'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
mavenCentral()
jcenter()
google()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
Project structure is shown below.

You mixed up with plugin version and distributionUrl. Plugin version should be classpath 'com.android.tools.build:gradle:3.0.1' or com.android.tools.build:gradle:3.1.0. Read Android Plugin for Gradle Release Notes.
buildscript {
repositories {
jcenter()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
}
}
And distributionUrl to GradleWrapper.
distributionUrl = https\://services.gradle.org/distributions/gradle-4.4-all.zip
Currently latest Version 3 gradle plugin available on android for which you have to use classpath 'com.android.tools.build:gradle:3.1.0'.
To be up to date see Configure Your Build.

Guess you mixed up Gradle and Android Gradle Plugin regarding their versions?
The latest Android Gradle Plugin is v4.0.0 as of April 2020, which maps to Gradle v6.1.1.
