안녕하세요, 음성 녹음 기능을 구현하려고 하는데 도저히 답을 모르겠어서 질문 올립니다.
음성 녹음 버튼을 누르면 해당 오류가 뜹니다.

Process 24384 terminated.여기서 제 코드 (VoiceRecordingActivity.java:85)를 가보면..
init(savedInstanceState);이 친구가 에러났다고 하는데 컴파일 에러는 없습니다.
이거 액티비티랑 xml이랑 미스매칭되서 나는 오류 아닌가요..? 저번에 이런적 있었는데.. 그때는 매칭을 잘못해서 여기서 에러가 났었거든요. 이번엔 아닙니다.
도저히 알 수가 없어서 질문드립니다..
다음은 전체 코드입니다. (아예 액티비티 전환이 안되고 너무 길어서 첨부안할까 했는데 혹시 몰라서 해봅니다.)
