You are passing GL_UNSIGNED_BYTE to your glDrawElements call but your index buffer is byte. Maybe that's causing the problem?
EDIT: I missed the part where you used DrawArrays. So unsigned/signed cannot be your problem completely.

Thanks for posting, will try to change to GL_BYTE later today.
Any other ideas?

Nope, the change to GL_BYTE didn't solve it....
There must be something strange in all this...

I haven't used glVertexPointer in a long time, but that looks odd
gl.glVertexPointer(3, GL.GL_FLOAT, 0, mVertexBuffer);
Shouldn't that be gl.glVertexPointer(3, GL.GL_FLOAT, 0, 0)
As far as I remember since you bind buffers the last parameter should be the start index inside the bound buffer. Since your are passing mVertexBuffer, the offset will be off by whatever number your buffer is.
The same thing applies to your glTexCoordPointer call and glDrawElements.
gl.glVertexPointer(3, GL.GL_FLOAT, 0, mVertexBuffer);
Shouldn't that be gl.glVertexPointer(3, GL.GL_FLOAT, 0, 0)

Thanks, will test this soon...
