Folks,
It is pretty easy to build your own installer package. There are two ways to do this.
1. Install the app on your phone and use javaloader to pull off the cod files. This isn't preferred as there maybe different versions for each handheld OS/device. Plus it doesn't preserve the original cod identifiers.
2. Spoof your useragent in firefox so that you can download the jad file. Not all sites require you to do this. Some will let you get to the mobile site very easily. Google isn't one of them. Google reads the useragent of your browser and will direct you away. Once you get to the mobile site, just download the jad file. In it will be links to all the cods. Just create an alx from that.
I prefer number 2 as it is cleaner, plus it allows for upgrades from the source site seamlessly.
In the case of google maps for 4.7 touchscreen OS and higher, the server structure is like this, just download each one:

http://m.google.com/maps/download/bi...ogleMaps-1.cod
http://m.google.com/maps/download/bi...ogleMaps-2.cod
http://m.google.com/maps/download/bi...ogleMaps-3.cod

See the attached alx file as an example of how you would do this for different devices (could easily be handheld OS versions as well).
