I have been asked more than once lately about the device on which I am testing code.

In order to produce some of the answers simply, I wrote a simple function getDeviceSpecs(). It occurred to me that this may be useful to others when reporting problems on the discussion groups.

The sample app uses this function to display some specs and copy them to the clipboard, ready to pass elsewhere.

getDeviceSpecs.js

var allBuilds = JSON.parse('{"1":{"level":1,"codename":"(no code name)","version":"1.0"}, ' + '"2":{"level":2,"codename":"(no code name)","version":"1.1"} , ' + '"3":{"level":3,"codename":"Cupcake","version":"1.5"}, ' + '"4":{"level":4,"codename":"Donut","version":"1.6"}, ' + '"5":{"level":5,"codename":"Eclair","version":"2.0"},  ' + '"6":{"level":6,"codename":"Eclair","version":"2.0.1"}, ' +  '"7":{"level":7,"codename":"Eclair","version":"2.1"}, ' +  ' "8":{"level":8,"codename":"Froyo","version":"2.2.x"}, ' +  ' "9":{"level":9,"codename":"Gingerbread","version":"2.3 - 2.3.2"}, ' +  ' "10":{"level":10,"codename":"Gingerbread","version":"2.3.3 - 2.3.7"}, ' +  ' "11":{"level":11,"codename":"Honeycomb","version":"3.0"}, ' +  ' "12":{"level":12,"codename":"Honeycomb","version":"3.1"}, ' +  ' "13":{"level":13,"codename":"Honeycomb","version":"3.2.x"}, ' +  ' "14":{"level":14,"codename":"Ice Cream Sandwich","version":"4.0.1 - 4.0.2"}, ' +  ' "15":{"level":15,"codename":"Ice Cream Sandwich","version":"4.0.3 - 4.0.4"}, ' +  ' "16":{"level":16,"codename":"Jelly Bean","version":"4.1.x"}, ' +  ' "17":{"level":17,"codename":"Jelly Bean","version":"4.2.x"}, ' +  ' "18":{"level":18,"codename":"Jelly Bean","version":"4.3.x"}, ' +  ' "19":{"level":19,"codename":"KitKat","version":"4.4 - 4.4.4"}, ' +  ' "20":{"level":20,"codename":"K or L","version":"4 or 5"}, ' +  ' "21":{"level":21,"codename":"Lollipop","version":"5.0"}, ' +  ' "22":{"level":22,"codename":"Lollipop","version":"5.1"} ' +  ' }')

The function getDeviceSpecs at the end of the code, can be pasted independently into a project an the string returned can be used however you see fit.
