    I was getting this error

    Error:Execution failed for task ':app:preDebugAndroidTestBuild'. Conflict with dependency 'com.android.support:support-annotations' in project ':app'. Resolved versions for app (26.1.0) and test app (27.1.1) differ. See https://d.android.com/r/tools/test-apk-dependency-conflicts.html for details.

    I was having following dependencies in my build.gradle file under Gradle Scripts

    dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support:support-v4:26.1.0'
    implementation 'com.android.support:support-vector-drawable:26.1.0'
    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'
    }
    

    So, I resolved it by commenting the following dependencies

    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'
    

    So my dependencies look like this

    dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support:support-v4:26.1.0'
    implementation 'com.android.support:support-vector-drawable:26.1.0'
    //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'
    }
    

    Hope it helps!

    Source: CodePath - UI Testing With Espresso

    1. Finally, we need to pull in the Espresso dependencies and set the test runner in our app build.gradle:
    // build.gradle
    ...
    android {
        ...
        defaultConfig {
            ...
            testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        }
    }
    
    dependencies {
        ...
        androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2') {
            // Necessary if your app targets Marshmallow (since Espresso
            // hasn't moved to Marshmallow yet)
            exclude group: 'com.android.support', module: 'support-annotations'
        }
        androidTestCompile('com.android.support.test:runner:0.5') {
            // Necessary if your app targets Marshmallow (since the test runner
            // hasn't moved to Marshmallow yet)
            exclude group: 'com.android.support', module: 'support-annotations'
        }
    }
    

    I've added that to my gradle file and the warning disappeared.

    Also, if you get any other dependency listed as conflicting, such as support-annotations, try excluding it too from the androidTestCompile dependencies.

    Try this :

    apply plugin: 'com.android.application'
    
    android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.example.yourpackagename"
        minSdkVersion 15
        targetSdkVersion 27
        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-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    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'
    }
