I'm searching for how to find the first boot of the application.
At first I checked the existence of shared object like this below.
----------------------------------------------------------
var mySharedObj:SharedObject = SharedObject.getLocal("SO");
if(mySharedObj.data.AAA == undefined || mySharedObj.data.AAA == null){
trace("First Boot");
mySharedObj.data.AAA = "test";
}else{
trace("Not First Boot");
}
----------------------------------------------------------
This script worked within the debugging on the MS Windows.
But once I installed it to the Android device, there appears a problem.
In the very first installation, it detect the first boot.
After that, I uninstall the app, and re-install the app.(i.e.the second installation)
On the first boot of the second installation, it detect the existence of the shared object despite my expectation.
I think this is due to the cache on the Android device.
It seems difficult to clear cache at the point of installation / uninstallation.
So I'd just like to know the approach to detect the FIRST BOOT, even though it is the second installation.
Regards.
