Could not resolve com.android.support:appcompat-v7:26.1.0 [dup

Answer 1

this work for me. add configurations.all in app/build.gradle

android {
    configurations.all {
        resolutionStrategy.force 'com.android.support:support-annotations:27.1.1'
    }
}

Answer 2

This work for me. In the android\app\build.gradle file you need to specify the following

compileSdkVersion 26
buildToolsVersion "26.0.1"

and then find this

compile "com.android.support:appcompat-v7"

and make sure it says

compile "com.android.support:appcompat-v7:26.0.1"
