Android 2.2 Apps2SD: Not what you were expecting
Now that Froyo is here (sortof) we’re starting to get a look at all the goodies that Google has put into Android 2.2 (aka “Froyo”), and Apps2SD is one of them.
“Apps2SD” is the ability to install downloaded apps to the sdcard, thus freeing up phone storage (which we’re going to need more of now that we can run Flash and Air apps). Of course, Cyanogen and his colleagues have enabled installing (or moving) apps to the sdcard through varied methods for some time now, but nothing “official” was available before Froyo.
The “problem” with the way Google implemented Apps2SD in Froyo that it’s up to the developer to toggle the switch to allow the app to be installed externally. Translated: not a single app of the 50,000+ in the Market today can be installed to the sdcard!
I would have preferred the opposite: for the user to select the preferred installation location (internal vs. external) and have all apps abide by that except where a developer specified otherwise.
