I will try and take this one.
if you have an APEX system and an adroid phone, go to market place and you are going to watn the Apex App that is made by HeneryH
then you go into the settings of the app and set your prefrences.
Title
URL for the controler
user name
password
etc
then you add the widget on the home page. you do not access the display info from where you launch the app.
so hold your finger where you want it on the home page and then selext Android widgets then select if you want the tall or short one. that will dispay the widget with the stats of your tank. If you want to expand it just tap on the widget. if you have questions let me know. I did this trial and error and got it going. this is they coolest thing ever, by the way. this was one of the larger selling points to getting android over Iphone. widgets and neat!
I am running an AC Jr so I have to use the ACSerial2Web app. It works great. I am going to donate to both authors right now.
if anyone else has any questoins let me know. I will try and answer them. I know nothing about the internal workings of these. just a little experience with the use of the apps and the aqua controllers.
I am running this on a Motorola Droid X2
