8 years ago @BrokenTeeth MainActivity테마를 @android:style/Theme.NoTitleBar 로 설정하셨다면 MainActivity가 어떤 Activity를 상속받으셨는지 확인해보세요. Manifest에서는 Appcompat Theme가 아닌데 MainActivity는 AppCompatActivity를 상속받아서 사용하면 위와같은 오류가 발생합니다.

아래 외국인분이 쓰신 오류랑 똑같이 나네요.
테마를 Appcomat 안쓰면 위와 같이 오류가 납니다.
AndroidManifest.xml에서 테마를 노 타이틀바를 주고 테스트 해보시면 됩니다.
<activity android:name=".MainActivity" android:label="@string/app_name" android:theme="@android:style/Theme.NoTitleBar">
