A free app for Android, by Adam Chýlek.
Fake Wifi (Xposed Module) is an application that provides a method to let other applications into thinking you are connected to the internet, even when your device is not connected to the internet.
How can this be useful?
Imagine you have a media box with an internet connection, and you are trying to watch a movie. The quality of the internet is not good enough to stream the movie in HD, so you want to watch it in lower quality.
You can use Fake Wifi to watch the movie in lower quality, without having to pay for a higher quality.
You can also use Fake Wifi to test your application.
