안녕하세요,는
임 전화를 (모두 밖으로 및 incomming)를 기록하고 프로세스가 내 응용 프로그램의 종료 시점에서 (데이터를 기록 촉진합니다 안드로이드에 대한 해결책 작업 는 오디오 파일 데이터에 개최 수 없습니다 전화 메모리). 상태가 CALL_STATE_OFFHOOK이면 녹음 서비스를 시작하는 PhoneStateListener.LISTEN_CALL_STATE가있는 BroadcastReceiver를 구현했습니다. 그런 다음 서비스를 시작하면 전화 녹음을 시도하는 새 스레드가 시작되고 PhoneStateListener.LISTEN_CALL_STATE가있는 다른 BroadcastReceiver는 전화 상태가 TelephonyManager.CALL_STATE_IDLE로 변경되면 녹음을 중지하는 메서드를 호출합니다.통화 기록/처리 서비스! - 안드로이드
생성 된 오디오 파일이 비어 있습니다. 내 서비스의 recorder.stop() 메소드가 호출되면 예외가 발생합니다. 오류는 어디에 있습니까? 내가 더 잘할 수 있을까?
