Android Studio : Failed to resolve: fragment-1.1.0

I want to add a library called material to my projects but it gives me the mentioned error in the title when I try to sync it. Android Studio 4.0.1.
build.gradle(app module)
apply plugin: 'com.android.application'
android {
compileSdkVersion 30
buildToolsVersion "30.0.1"
defaultConfig {
applicationId "com.example.app"
minSdkVersion 14
targetSdkVersion 30
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
/*implemention for material shown below*/
implementation 'com.google.android.material:material:1.3.0-alpha02'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

What's the right material design library to use in my gradle, i've tried different solutions, it's not building successfully

I'm trying to test the FAB concept in my app but it's not working following the guidelines i got maybe because i didn't understand it well, see my gradle file below:
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "study.timmy.micah.materialdesignpractices"
minSdkVersion 15
targetSdkVersion 28
versionCode 1

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}

Can you help? thank you

Follow this

}
apply plugin: 'com.google.gms.google-services'

Update gradle and firebase versions as required.
'com.google.firebase:firebase-auth:16.0.1:15.0.0' Make it
'com.google.firebase:firebase-auth:16.0.1' Or anything that is compatible with your gradle.

Is it possible to target Android 28 (eg`targetSdkVersion 28`) and use both appcompat-v7 and Firebase?

Has anyone managed to target Android 28 (eg set targetSdkVersion 28) and use Firebase? My build.gradle is as below:
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.google.firebase.example.fireeats"
minSdkVersion 28
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-rc02'
implementation 'com.google.firebase:firebase-core:16.0.3'
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'
}
apply plugin: 'com.google.gms.google-services'
Android Studio warns of mixed versions: Found versions 28.0.0-rc02, 26.1.0. Examples include com.android.support:animated-vector-drawable:28.0.0-rc02 and com.android.support:support-media-compat:26.1.0
Is Firebase 16.0.3 incompatible with the Android 28 support lib?

At time of writing, Firebase depends on the support library versions 27 so you do need to provide explicit overrides. See the working build file below.
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.google.firebase.example.fireeats"
minSdkVersion 28
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:support-media-compat:28.0.0' // NEED TO ADD
implementation 'com.android.support:support-v4:28.0.0' //NEED TO ADD
implementation 'com.google.firebase:firebase-core:16.0.4'
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'
}
