```Hi

Iam developing an augmented reality browser on my ownn...........But
not able to get the screen cooridinates....

I will discuss my whole problem here.....as im not sure at which point
i stuck up...

I hav a set of latitude longitude values for different points.Taking
them Iam calculating x,y,z coordinates for each point.Using left
handed rule ie.x towards east y towards north and z upwards
values which i get are:-

x=(a+altitude)*(Math.cos(latitude)*Math.sin(longitude));//x
y=(a+altitude)*Math.sin(latitude);//y
z=(a+altitude)*(Math.cos(latitude)*Math.cos(longitude));//z

where a=app 80m i have taken radius of earth.The origin is defined to
be at centre of earth(ECEF)

SensorManager.getRotationMatrix(RTmp, I, grav, mag);
SensorManager.remapCoordinateSystem(RTmp, SensorManager.AXIS_X,
SensorManager.AXIS_Z, R);
SensorManager.getOrientation(R, values);
azimuth = (float)((values)*(180/Math.PI)); //in degree
pitch = (float)((values)*(180/Math.PI)); //in degree
roll = (float)((values)*(180/Math.PI)); //in degree

Then using perspective projection Iam calculating screen coordinates.
Iam refering below link for perspective projection:--

http://en.wikipedia.org/wiki/3D_projection#Perspective_projection

In the above link Iam replacing thetax with pitch,thetay with
roll,thetaz with azimuth.

Watever screen coordinates i got from above calculations Iam plotting
a circle using canvas.But Iam unable to see anything.

Pleae help as Iam stuck up with this for the past 3 dayzzz :( :(

```Hi there
I've made a live wallpaper that swaps images in the background.
My problem is when I press "Set Wallpaper"\some icon on home activity\launch
activity button etc, the background react to this touch and changes the
image..
How can avoid changing the background when the user press those things?

Thanks : )

p.s
It changes the image also when the user performs a long press, but I think
can handle it just by calculate the difference between the DOWN & UP events
