Women Safety Android Application

Hello All, I am working on freelance project and Want to know the source code of women safety application projects. Basically, The women’s safety application will aim at providing the utmost safety to women. All they need to do is register themselves on the application and as soon as they sense something shady, they’ll press the power button thrice, and consequently, their location will be sent to the nearest police station and emergency contacts. If the woman reaches a safe space, she can press the stop button. I have taken this project reference from here. Can anyone give me some references for this project source code?
