Hey there.. I have an app that download an xml from internet and store this in a temporarydirectory...
my problem is... If I open my app without connection I get my error msg but if I open with internet connection and after that I exit my app, turn off my internet and re-open my app.. I don`t get the network error msg
it's seems that my .xml still there, but if I close my app the xml should be deleted no?
