로그에 이런 오류가 뜨는데 ㅜㅜㅜ

Question

블루투스채트랑 거의 동일한 소스입니다.

버튼을 누르면 블루투스 채트 화면으로 전환인데

보시고 답주세요 ㅠㅠ

제생각에는 권한문제 같아서 메니페스트도 같이올립니다.

Answer 1

onCreate() 메소드 아래

getWindow().requestFeature(Window.FEATURE_ACTION_BAR);

한번 해보세요

Comments

답변에 올렸습니다 ㅠㅠ
그래도 에러뜨는데 어떡해야할까요

---

325번 줄에 null point exception 인것 같은데 .. setStatus 메소드 내용을 주석 처리하고 해보세요 getActionbar 에 null 값 들어가는 것 같은데..

---

에러는 안뜨는데 actionbar에 있던 모든내용이 없어집니다 ㅠㅠ

---

getActionbar 에 null 값 들어가서 에러 나는것 같은데요.
manifest 파일에서 android:theme 를 그냥 기본으로 바꿔보세요
android:theme="@style/AppTheme"
