Hi, I am trying to implement a application on android that generates
mouse movements. I am currently working on android 2.2 operating
system. We modified some parts of kernel by ourselves. When you plug-
in a mouse from USB port externally, mouse pointer icon appears on the
screen and then you can use mouse with all of it's functions. After 3
seconds without interaction, mouse pointer disappears on the screen.
I wrote a code using jni and ndk. I implemented mouse movement with
xwarppointer function in X11/Xlib.h. But in the ndk-build step, it
gives en error as shown below:
Compile thumb : ndk_demo <= ndk_demo.c
jni/ndk_demo.c:3:22: error: X11/Xlib.h: No such file or directory
jni/ndk_demo.c: In function 'Java_com_marakana_NativeLib_hello':
jni/ndk_demo.c:20: error: 'Display' undeclared (first use in this
function)
jni/ndk_demo.c:20: error: (Each undeclared identifier is reported only
once
jni/ndk_demo.c:20: error: for each function it appears in.)
jni/ndk_demo.c:20: error: 'd' undeclared (first use in this function)
What is the error, why ndk-build does not see the X11/Xlib.h and it's
functions. Should I continue to solve this problem to generate
movement of mouse icon or, is there any other methods that I can use
to generate movement of mouse icon. If you can you give me a roadmap
about that problem, i will be appreciated.
Maybe I have to use the driver function calls to generate movement of
mouse pointer, but there must be an exact way to generate movement. I
will try any solution suggestion that will come from you.
Thanks.

You have been told in your earlier thread that Android doesn't provide
X11 headers and libraries. Android isn't using/supporting the Xserver at
all.
So either you port the Xserver to android or you fix your code to not
depend on it.
Best regards.

I understand, thanks. Can you give me an idea about how to port the X
server to android.
And is there any different way to implement the application without X
server ?

that sounds like a gargantuan job!

I think it is more viable to move away from X, than to bring it with you..
it is a heavy load.
