In my application, I have a NDK native code that uses OpenGL 1.0 to
apply a texture to a rectangle in order to draw an image on the
screen. It is working fine on the emulator, but when I test it on the
HTC HERO android device, it only draws a white rectangle without
texture. Anybody else had the same problem? Did anybody find a
solution?
Here is how I initialize openGL in native code:
GLint crop[4] = { 0, 144, 176, -144 };
glBindTexture(GL_TEXTURE_2D, 0);
glTexParameteriv(GL_TEXTURE_2D, GL_TEXTURE_CROP_RECT_OES, crop);
glTexParameterx(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glTexParameterx(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameterx(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
glTexParameterx(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);
glTexEnvx(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE);
glEnable(GL_TEXTURE_2D);
glColor4f(1,1,1,1);
And here is how I draw the frame in native code:
glClear(GL_COLOR_BUFFER_BIT);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, w, h, 0, GL_RGB,
GL_UNSIGNED_BYTE, pixels);
glDrawTexiOES(0, 0, 0, w, h);
