Answer 1

Change your compileSdk to 33 (or whatever the latest happens to be now).

compileSdk 33

defaultConfig {
    applicationId "com.example.lifecycle"
    minSdk 21
    targetSdk 30
    versionCode 1
    versionName "1.0"

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
