Felix Palmer의 android-visualizer를 작동시키는 방법은 무엇입니까?

Question

Felix Palmer에서 "android-visualizer"코드를 다운로드하여 작동 시키려고했지만 아래에 붙여 넣은 오류가 있습니다. 이 기능을 작동 시키려면 어떻게해야합니까?

저희 회사는 OpenGL 3D 효과가있는 Android 시각화 기능을 개발 중입니다. 가능한 경우 "android-visualizer"의 코드를 다시 사용하고 싶습니다.

당신은 펠릭스 파머 비주얼은 단순히 미디어 플레이어를 제거하고 메인 출력 스트림에 연결 사용할 수 있습니다. 그냥 가 MediaPlayer를에 대한 참조를 제거하고 같은 비주얼을 인스턴스화 :

new Visualizer(0); 

이 테스트 목적으로 할 것 같아요. 비주얼 라이저 앱을 시작한 후 음악을 재생하십시오.
