The emulator uses a software renderer called PixelFlinger. The G1 uses the MSM7200 chip as a hardware renderer. You may get slightly different results.
If you are trying to draw lines that are only 1 pixel wide, ensure the following: 1) You are in a native resolution to the screen you're rendering on (turn all the density and screen-size stuff on in the manifest to avoid compat mode) 2) You draw the lines centered on their pixel, so they look a half pixel off. -- To draw a horizontal line across the top row of pixels, you need to make the line with 1.0f and have y be 0.5f (because it will draw from 0 to 1 that way) 3) Make sure you don't have any z-fighting. Drawing 2 things on the exact same plane with depth-test turned on causes bad results on many opengl implementations.
