The app I am working on is supporting android 2.3 upwards. As the download manager does not support https in 2.3(I can’t comprehend why), I am implementing my own version.<\/p>\n
The problem I have is if android changes network (wifi to 3g etc) when downloading content I am getting the following error.<\/p>\n
