I'm using code to query the current EGL config similar to this:
int [] curConfigId = new int [1];
egl.eglQueryContext (curDisp, curCtxt, EGL11.EGL_CONFIG_ID,
curConfigId);
EGLConfig [] cfgs = new EGLConfig [1];
int [] numCfgs = new int [1];
egl.eglChooseConfig (curDisp, new int [] { EGL11.EGL_CONFIG_ID,
curConfigId[0], EGL11.EGL_NONE }, cfgs, 1, numCfgs);
It's hard to get detailed info on EGL but for all I know, this should
work - except that it doesn't. In particular, the EGLConfig this gets
me has a 16bit depth buffer whereas actually there are no ancillary
buffers attached to the current context or surface.
In contrast, if I just run eglChooseConfig(), requesting the first
config with RGB 565, I get the current config.
(I can tell if I got the correct EGLConfig because I use it then to
make a pbuffer which I subsequently eglMakeCurrent() with the current
EGLContext. This fails with EGL_BAD_MATCH (I think) if the config
used to create the pbuffer was not compatible with the current
context's config.)
Am I messing up somewhere, or is this a bug in Android EGL implementation?
