We are developing an Android data-entry application for use in places with very limited connectivity. We'll be using old/discarded Android devices in areas outside towns in Kenya, Uganda, etc. where there is no wi-fi; the devices themselves are not signed to a phone service. Users collect data in the field & return home, where typically internet access is available only via shared PCs at internet cafes.
I'm wondering if there is an easy way to connect an Android phone to a PC via the USB cable such that it shares the PC's internet connection for outbound connections? ie. reverse tethering... which seems to be a common topic, but all of the solutions seem to involve installing software on the PC, which I'm not sure would work at a cafe. Is there "an app for that"?
I can provide more details if it helps find a solution! Thanks
