While working with OpenGL in Android devices, I found a bit trouble with Float Point Values problem.
Some of the older version devices (mostly android 2.0 or less) hardware does not support floating point. Hence if we draw any 3D image using OpenGL, it will not display that drawing on older devices. To work on OpenGL ES it is better to draw the graphics using fixed point values.
List of devices that supports floating point values :
All Samsung Galaxy mobiles.
HTC Salsa, T-Mobile G2, AKA, HTC Dream,
Droid, Nexus
Motorola Milestone, NEON,
ARM-based Qualcomm MSM7201 CPU does not have VFP (floating point coprocessor) and therefore floating point calculations have to be done via software-float.
