i draw a cube with two sides textured(320*430 png) and let it rotate
between the two sides, but it's sad to get a 16 FPS on emulator and 9
FPS on the real phone. i don't known whether i have used the hardware
acceleration on my phone.
so i tried many parameters in OpenGLES ,finally i found i can set a
value in my CubeView(inherit from GLSurfaceView )'s constructor ,
public CubeView(Context context)
{
super(context);
this.getHolder().setType(SurfaceHolder.SURFACE_TYPE_HARDWARE); //
here is the crucial line
mRender = new CubeRender(this);
this.setRenderer(mRender);
}
setType with the value SURFACE_TYPE_HARDWARE can improve the OpenGL
rendering speed, and i get a rate of 14FPS on real phone, but has no
effect on emulator( i guess emulator didn't use hardware to render)
but the 14FPS also is not enough for me , 18 -- 20 may be
acceptable . the qualcomm demo neocore can render a complex arena on
25-27 FPS in my phone.
so what's the problem with me, is there another ways to use the
hardware acceleration in OpenGL ES .
my phone has a cell of qualcomm MSM7201A with a hardware acceleration.
