IKROWNI,
I know this is well years late, but have successfully integrated into Google Now services using the Robo Browser and Jame's help. The attached Macro should give you a simple Google now command. I am still playing with the Google Now feature's and figuring out what all I could read/write to it, but it does have some nice features!
<macro>
<action actiontype="RoboB.Select" repeat="1" logic="False"><paramstring>GoogleNow</paramstring></action>
<action actiontype="RoboB.Navigate" repeat="1" logic="False"><paramstring>https://www.google.com/#q=Remind+ME+to+Walk+The+Cat+at+5PM&safe=off</paramstring></action>
<action actiontype="RoboB.Wait" repeat="1" logic="False"><paramstring></paramstring></action>
<action actiontype="RoboB.Show" repeat="1" logic="False"><paramstring></paramstring></action>
<action actiontype="RoboB.ElementByID" repeat="1" logic="False"><paramstring>act-rmd-send</paramstring></action>
<action actiontype="RoboB.Click" repeat="1" logic="False"><paramstring></paramstring></action>
</macro>
I will post a bunch of samples soon as I sort some things out. Of course be sure that your default browser is logged into google so that it can recognize you and signed in as same account as your android phone. I have confirmed on my Galaxy S3 just now I was told to walk my Cat... the Cat however did not agree
