Android Studio NDK-OpenGL-交換緩存畫面eglSwapBuffers()返回EGL_BAD_SURFACE

將『風水羅盤』由『Windows』移稙過『Andord』. 係交換緩存畫面『eglSwapBuffers()』返回『EGL_FALSE』, 『eglGetError()』返回『EGL_BAD_SURFACE』.

EGLBoolean ret = eglSwapBuffers(display,surface); if(ret == EGL_FALSE){ GLint error = eglGetError(); if(error == EGL_BAD_SURFACE){ } }

係『Windows』有『Winmain()』入口. 可以控制冚個整游戲運作, 係 『Winmain()』 游戲『運行』『渲染』都係主線程行.

而 『Andord』冇『Winmain()』. 游戲『運行』『渲染』要係新線程『Thread()』行. 而『EGLContext』同『EGLSurface』需係同壹線程『Thread()』生成, 唔係『eglSwapBuffers()』投『EGL_BAD_SURFACE』錯誤碼.

知錯係邊就易整, 將egl()程式擺係新線程『Thread()』行,而非『 onSurfaceCreated()』.
