Well, I too faced the same problem here is how I fixed it

• Goto app level Gradle file

There you will find what are all the config's you have set up. In my case here

android{
    **compileSdkVersion 26**
    defaultConfig {
        applicationId "com.xxxxxxxxxxx.yyyyyyyy.zzz"
        minSdkVersion 19
        **targetSdkVersion 26**
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    **implementation 'com.android.support:appcompat-v7:26.1.0'**
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'
    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 here just change the compileSdkVersion & targetSdkVersion from 26 to 27 and

from dependencies change support appcomat

from   implementation 'com.android.support:appcompat-v7:26.1.0' 
to     implementation 'com.android.support:appcompat-v7:27.1.1'


android {
    **compileSdkVersion 27**
    defaultConfig {
        applicationId "com.xxxxxxxxxxx.yyyyyyyy.zzz"
        minSdkVersion 19
        **targetSdkVersion 27**
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    **implementation 'com.android.support:appcompat-v7:27.1.1'**
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'
    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'
}

Got Fixed !!!
