How to switch Wifi On and Off automatically or remotely in your Android App? – Complete Source Code

This video shows the steps to create an Android App which can be used to control the state of your Wifi between ON and OFF. The concept shown in this video is very simple. However, the use cases to control the state of the wifi could be many which has been briefly discussed in this video. Some of the use cases could be to control the wifi remotely by sending the command over channels such as SMS, firebase database update, etc. It can also be controlled at a pre-set time using some kind of timer or alarm clock concept.
