Answer 1

Update your minSdkVersion to 14 in build.gradle file.

Answer 2

UPDATE your app level gradle file, set minSdkVersion 14

Try this,

  defaultConfig {
        minSdkVersion 14
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

After updating the gradle file, once clean and rebuild your project
