Error: "The application could not be installed: INSTALL_FAILED_OLDER_SDK The application's minSdkVersion is newer than the device API level"

Relevant portion of my build.gradle:

android {
    compileSdkVersion 'android-Q'
    buildToolsVersion "29.0.2"
    defaultConfig {
        applicationId "com.example.mykotlintutorials"
        minSdkVersion 'Q'
        targetSdkVersion 'Q'
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
