NightLite - HackXX2019

The safefy of any person is very important and most women would agree that they have experienced a time when they felt unsafe walking by themselves. NightLite offers a solution to this feeling of fear to any person.

Motivation

As a team of young women, we all understood how it felt to walk alone in the dark with no one around. We constantly heard stories of young girls getting abducted, so we always had this thought in the back of our minds that something so unthinkable could potentially happen to us. An app like NightLite would provide some relief while you are walking through a suspicious area.

Implementation

There are four tabs on the app that provide a different function to the user.

The first tab contains a button that the user would tap and hold when they feel unsafe. Once they feel that they are out of danger, they can let go of the button and NightLite will ask for a password to confirm that the user is in fact safe. If the password is not inputted, the app should contact the emergency contact that is recorded in the phone, and the location of the user will be sent to the authorities.
The second tab would contain a bell that the user can press to scare off any potential threats. It would play a loud sound until the user believes they have warded the danger.
The third tab is a map that potentially would send out a location to the authorithies. It tracks the location of the user while they are on the app, and implements a Google Maps API.
The fourth tab is where the user can make changes to their settings. There is an option to change the emergency contact and another to change their passcode.

I worked on the Settings page on the Android app. I connected the front end of the page to the back end. There is a text box that allow the user to input a phone number and a button that pulls up a window for changing the password. I needed to ensure that the buttons would take the user to the correct place. There is a functionality in the password window that checks to see if the passwords match. If they do not, the window will not be able to be closed. The user can also tap cancel to exit out of the window.

I worked on the start page (front and back end coding) of the app, which is the Safety Button that can be held until the individual is on a safer area. The button prompts a password input once let go, and if password is not put in the given amount of time, the authorities, or the number the person has chosen to notify, will be called and alerted.

I worked on both the front and back end of the location tracker, which implements the Google Maps API to visually represent the user's location and would potentially send crucial data to authorities to locate the user. Working with Android Studio was definitely a first for me and a challenge, but I enjoyed learning how to utilize XML and experiencing how mobile apps are developed.

I worked on the front end and back end of the "flare" button, which is meant to play a sustained alarm when pressed to alert any nearby people and/or scare away a potential attacker.
