As play store doesn't provide me the permission to upload one apk with a targetSdkVersion of 25. So, I upgraded my targetSdkVersion from 25 to 27 and downloaded the all necessary libraries by adding dependencies.

I am provided below the entire build.gradle file code with the changes I made-

    buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

repositories {
    maven { url 'https://maven.fabric.io/public' }
}

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    buildToolsVersion '26.0.2'
    defaultConfig {
        applicationId "com.myApp"
        minSdkVersion 17
        targetSdkVersion 27
        versionCode 2
        versionName "1.1"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    dexOptions {
        javaMaxHeapSize "2g"
    }

    repositories {
        mavenCentral()
    }
}


dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')

}

But after syncing I am getting the following errors-

Information:Gradle tasks [:app:generateDebugSources, :app:generateDebugAndroidTestSources, :app:mockableAndroidJar] C:\Users\admin.gradle\caches\transforms-1\files-1.1\appcompat-v7-27.1.0.aar\ad0857f7c335bc06a588407b354d6c8b\res\values\values.xml

As I can't rollback back to targetSdkVersion 25.Please suggest me any solution to solve this issue and upgrade targetSdkVersion to 27.

Possible duplicate to this question

TLDR Try renaming the library attribute to something else (textFont) ¯\_(ツ)_/¯

a) you need to use the correct build-tools, which are version 27.0.3. while I merely wonder why you updated to API 27 instead of the current API 28; this would use build-tools version 28.0.3.

b) and you have to fix these invalid resources; one duplicate attr/font clashes with com.android.support:appcompat-v7:27.1.0. this comes from any occurrence of <attr name="font" format="string"/> in the project's XML, which has to be removed or renamed.

c) adding the buildscript (most likely twice) into the module-level build.gradle is non-sense. apply plugin: 'com.android.application' also exists twice; this build.gradle is a mess.

Try to add :

        classpath 'com.android.tools.build:gradle:3.2.1'

to the project-level build.gradle in dependencies section ( maybe you need to upgrade gradle to 4.6 in gradle-wrapper-properties ) :

distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip

And increase buildToolsVersion to '28.0.3' in app-level build.gradle. Then clean project or do './gradlew clean' in terminal in your project directory ( possible with android studio terminal ).
