The pppwidget folder on /sdcard as well as the unpacking of the binaries should happen on the first call of the widget (actually placing it on the "desktop"), right after the root check. Did you do that successfully?although not developed form my tab, i tried and it appears to not install corretly on the acer a510(rooted). no pppwidget dir is create nor can i find the files under their standard directories, ie usb mode switch. as a result just get an error from pppwidget when i plug in a wireless stick. (sierra wireless 306 and sierra wireless 598usb).
The binaries are not in their "standard directories". The widget does not intrude any system folders - one of my goals is to leave the system alone apart from using the "su" tool. There is only the app tree in /data/data and the folder in /sdcard.
