real3D를 이용하여, 3d개발을 하고있습니다.
surfaceView의 draw를 이용하여, 3d를 그리고있는데 lockCavnas()가 null을 return하네요ㅠ.ㅠ
똑같은 그림이 두개인건 신경쓰지마시고, 숫자밑에 영문자가 4x10 형태로 40개가 나타나야하는데,
원인이 뭔지모르겠는데 전부나타나지않고 랜덤하게 나타납니다.
surface view를 이용해 그리고있습니다.

하는대로 전부다 그려지지 않기에 다른 예제를 보면서 draw를 넣어봤더니 죽네요ㅠㅠ

에서, 디버깅해보니까 c가 null값을 가집니다.
logcat은 3d lib을 사용해서그런지, 평소에 보던거랑은 달리

이런식으로만 뜹니다ㅠ.ㅠ 도와주세요
