I think I found a solution to this issue - my game uses OpenGL and crashes horribly when I try to detect hardware acceleration on the Samsung Moment. Luckily my coworker just got a Moment so I had a chance to debug the situation. FYI, neither DroidBench nor NeoCore show up in the Market for the Moment. Speed Forge 3D runs fine on the Moment.
The EGL configs that allow hardware acceleration have the EGL_CAVEAT value set to EGL_UNKNOWN on the Moment. If you are writing your own EGL config chooser, you'll need to take this into account. The steps for my config chooser are as follows: 1. Look for all configs closest to RGB==565 and with EGL_CAVEAT == EGL_NONE 2. If nothing is found, look for all configs closest to RGB==565 and with EGL_CAVEAT == EGL_SLOW_CONFIG I assume that useful configs appear in either of the two searches. This is an incorrect assumption with the Samsung Moment since the hardware accelerated configs have EGL_CAVEAT == EGL_UNKNOWN. Reading the EGL spec, this seems to be a weird situation. The steps for my config chooser are modified as follows: 1. Look for all configs closest to RGB==565 and with EGL_CAVEAT == EGL_NONE 2. If nothing is found, look for all configs closest to RGB==565 and with EGL_CAVEAT == EGL_DONT_CARE Basically I do a narrow search for known hardware accelerated configs, then a broader search that hopefully returns something useful. The broader search is similar to what GLSurfaceView does by default. FYI, GLSurfaceView with the default EGL config chooser seems to run fine on the Samsung Moment. I mentioned that my game would crash horribly using the first sequence of config choosing - apparently the second search for EGL_SLOW_CONFIG returns PixelFlinger (software renderer) configs that are created just fine. When I try to finish() the current activity, my app segfaults. I guess the Moment has trouble using software renderers. Hope this helps.
