Answer 1

change

compile 'com.android.support:appcompat-v7:26.0'

to

`compile 'com.android.support:appcompat-v7:26.+'`

worked for me fine.

Answer 2

1 - in build.gradle change my supportLibVersion to 26.0.0

2 - in app/build.gradle use :

implementation "com.android.support:appcompat v7:${rootProject.ext.supportLibVersion}"

3 - cd android

4 - ./gradlew clean

5 - ./gradlew assembleRelease

Answer 3

If you already use jitpack.io or any repository. You can add google repository like this:

allprojects {
    repositories {
        maven { url "https://jitpack.io" }
        maven { url "https://maven.google.com" }
    }
}

Answer 4

Adding the below content in the main gradle has solved the problem for me:

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

Answer 5

My issue got resolved with the help of following steps:

For gradle 3.0.0 and above version

1. add google() below jcenter()
2. Change the compileSdkVersion to 26 and buildToolsVersion to 26.0.2
3. Change to gradle-4.2.1-all.zip in the gradle_wrapper.properties file

1. Add this in build.gradle(Project:projectname)

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

2. Add this in build.gradle(Module:app)

   dependencies {
     compile 'com.android.support:appcompat-v7:26.1.0'
   }
