An error occurs configuring project:app in developing android app using gradle build tools

I am new to android development and I 'm building android app. I'm using gradle and I got the error message A problem occurred configuring project ':app'.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.0'
//classpath 'ext.supportLibraryVersion = 27.1.1'
classpath 'com.android.support:support-v4:27.1.1'
classpath 'com.google.gms:google-services:4.3.2'
// 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
}
The above code is the project level of build.gradle file.
The following code is the app level of build.gradle file.
apply plugin: 'com.android.application'
android {
compileSdkVersion 27
defaultConfig {
applicationId "mm.com.fairway.firebaseauth"
minSdkVersion 22
targetSdkVersion 27
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 'com.android.support:appcompat-v7:27.0.2'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
implementation 'com.google.firebase:firebase-analytics:17.2.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}
apply plugin: 'com.google.gms.google-services'
I searched the solution to fix this error and I don't find the solution yet. Any ideas for this error and Thank you.

classpath 'com.android.support:support-v4:27.1.1
The above line is in the wrong Gradle file. Also change it from classpath to implementation.
So something like this:
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.5.2'
//classpath 'ext.supportLibraryVersion = 27.1.1'
classpath 'com.google.gms:google-services:4.3.2'
// 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
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "mm.com.fairway.firebaseauth"
minSdkVersion 22
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 fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:support-v4:28.0.0'
implementation 'com.google.firebase:firebase-analytics:17.2.1'
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'
}
apply plugin: 'com.google.gms.google-services'
Do note, I updated the project to 28 and other dependencies were also upgraded. I did this as I don't have SDK 27 installed anymore.

Upgrading your Gradle build tools to 3.2 or higher will solve this problem.
For example:
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.0'
//classpath 'ext.supportLibraryVersion = 27.1.1'
classpath 'com.android.support:support-v4:27.1.1'
classpath 'com.google.gms:google-services:4.3.2'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
This solved it for me and seems to have solved it for this other person as well:
I have a gradle sync error JAVA_LETTER_OR_DIGIT when trying to add Firebase to my android project

Unable to resolve error of gradle version when migrating to AndroidX

When I tried to migrate my own project to AndroidX, the error message appeared on a error dialog:
The gradle plugin version in your project build.gradle file needs to be set to at least com.android.tools.build:gradle:3.2.0 in order to migrate to AndroidX.
Then I googled this error on the Internet. A site was found that it said classpath 'com.android.tools.build:gradle:3.2.0' has to be added to the build.gradle. Therefore, I added the line to the build.gradle like this:
apply plugin: 'com.android.library'
android {
compileSdkVersion 28
defaultConfig {
minSdkVersion 19
targetSdkVersion 28
versionCode 1
versionName "1.0"
multiDexEnabled true
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 'com.android.support:multidex:1.0.3'
implementation 'com.android.support:support-core-utils:28.0.0'
implementation 'com.android.support:appcompat-v7:28.0.0'
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'
}
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.0'
}
}
allprojects {
repositories {
google()
jcenter()
}
}
However, the same error happened. Am I missing something?

Check your build.grade of Project level ( Not Module )
And change the version of the android gradle plugin:
buildscript {
...
dependencies {
...
classpath 'com.android.tools.build:gradle:3.4.1' // it should be more than 3.2.0
}
}

Update your project build.gradle to use the latest version of the plugin:
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.3'
classpath 'com.google.gms:google-services:4.0.1' // <== CHANGED
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

Failed to resolve support-v4 27.1.0 dependency in Gradle

You can see the error on the image shown above.
I have tried to install Firebase using its assistance (tools/Firebase) then I tried to do it normally.

As #tyczj says, you can't use classpath 'com.google.gms:google-services:3.0.1' in your module build.gradle (like app module) dependencies block. You only can use it in your project or root build.gradle dependencies block.
