Android OpenGLES 기기 문제

Question

최근 Android로 OpenGLES 학습을 시작했습니다. 렌더링과 함께 GLWallpaperService 클래스로 livewallpaper를 만들고 있습니다.

Android 시뮬레이터의 문제는 애니메이션을 표시 할 수 있지만 이며 Android 기기 (HTC Incredible S) FPS로 테스트하는 동안 45-50 정도가 유지되지만 화면에는 아무 것도 표시되지 않습니다.

다음은 코드 스 니펫입니다.

열린 글자를 올바르게 설정했다면 문제가 그리는 곳이 아닌 경우가 자주 있습니다. 보기의 범위를 벗어날 수 있습니다. 귀하의 번역본 등에 매우 조심하십시오.
