First off OpenGL ES 1.x is completely different from 2.x.
1.x has a fixed pipeline and 2.x has a programmable pipeline determined by vertex & fragment shaders.
They are not interchangeable.
Are you doing NDK development as there isn't an official 2.x Java binding yet, but you can find one here:
Also check out this recent thread for an overview of GL ES 2.x as a very similar question to yours was asked:

Also as far as I'm aware most devices that support GL ES 2.x should also offer support for 1.x You should still be able to use 1.x for the Legend.
