Failed to Resolve: Com.Android.Support:Appcompat-V7:27.+ (Dependency Error)

Failed to resolve: com.android.support:appcompat-v7:27.0.0

Installing the newest Android Studio version solved the problem

Failed to resolve: com.android.support:appcompat-v7.27.+

Gradle DSL method not found: 'google()'

Set

compileSdkVersion 27
buildToolsVersion "27.0.3"

Make sure added google() in Your PROJECT LEVEL build.gradle section.

allprojects {
    repositories {
        google()
        jcenter()
        maven { url 'https://maven.google.com/' }

    }
}

It will be better if you set PROPER version.

compile 'com.android.support:appcompat-v7:27.1.1' 

FYI

Use implementation instead of compile. i.e

implementation 'com.android.support:appcompat-v7:27.1.1' 

After that, Clean-Rebuild-Run.

28.0.0 is the final version of support libraries. Android has migrated to AndroidX. To use the latest android libraries, Migrating to AndroidX

Edit: Versions 28.0.0-rc02 and 28.0.0 are now available.

I don't see any 28.0 version on Google Maven. Only 28.0.0-alpha1 and 28.0.0-alpha3. Just change it to either of those or how it was previously, i.e., with .+ which just means any version under 28 major release.

For an alpha appcompat release 28.+ makes more sense.

Try this :

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.brazzaqi.myapplication"
        minSdkVersion 15
        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'
        }
    }
}

You need to add the google maven to your root build.gradle like this:

allprojects {
repositories {
    jcenter()
    maven {
        url "https://maven.google.com"
    }
}
}

For Gradle build tools plugin version 3.0.0, you can use google() repository (more at Migrate to Android Plugin for Gradle 3.0.0):

allprojects {
repositories {
    jcenter()
    google()
}
}

Got the solution.
Just
Replace

compile 'com.facebook.android:facebook-android-sdk:[4,5)'

by

compile 'com.facebook.android:facebook-android-sdk:4.26.0'

Failed to resolve: com.android.support:appcompat-v7:30.0.0

It happens because the support libraries v.30 don't exist.

Use the androidx library:

implementation 'androidx.appcompat:appcompat:1.1.0'

or use the last support library:

implementation 'com.android.support:appcompat-v7:28.0.0'
