eMadad - A Sword of Women

eMadad addresses the most devastating problem of human civilization to date through innovative technology and simulation. The app manifests mainly four features, which are: emergency SOS service; hidden camera detectors, either manually or by the electromagnetic field detection simulation developed by us; women's struggle and empowerment news to get empowered; and a siren alarm.

Description
It is a complete women's safety app where a girl or woman has to save the phone numbers of her relatives,and whenever she is in trouble, she can tap the power button three times, and then an emergency message with her live location is sent to her relatives, and a phone call is also made to her first relative even when the phone is locked. There is no need to unlock the phone and open the app. If she is in more trouble and wants to deviate from the culprit, then she can tap the power button three more times to start a siren alarm.

Brief Process Flow

When we tap the launcher icon, a splash screen merged with the lottie animations is displayed.
After that, we need to give some permissions to the app, and then the home screen with 7 CardView buttons is displayed.
These Seven Card View buttons include Emergency SOS, Hidden Camera Detector, Women's News, Siren Alarm, App Tour, About Us, Share, and Save Lives.

When we enter into:
1. In an emergency SOS service, the phone number of relatives is saved with the help of shared preferences in the form of a key value pair, and when we tap on the try it button, a phone call is made with the help of implicit intent, and a message is sent with the help of the SMS Manager class. This message is also embedded with the live location of the user, which is provided by the help of the fusedlocationprovider client API.

2. Now, we also need to trigger this functionality even when the phone is locked. So, whenever the phone is in a locked state, the app is in a paused state; therefore, we can't perform any action in the background. So a background service is registered inside the app so that even if the phone is in a locked state, some functionalities could get executed.

Now, a broadcast receiver is registered inside the background service in order to receive the broadcast message from OS about the screen ON/OFF state to count the power button tap count.



Hidden camera detector, then we must be aware that all electronic cameras emit electromagnetic radiation, and these electromagnetic radiations strengths in all three directions are detected by the magnetometer sensor of our phone. If the resultant is greater than a certain range, then the phone starts beeping.

3. Women's News, then it shows only women’s news, which is populated by the data of a news API fetched with the help of the retrofit library.

4.Siren Alarm: Then this screen starts a siren alarm in looping with the help of the Media Player API.

5. About Us: The user can read about us and can also contact us with the help of implicit intents.

6. App tour, then get the whole tour of the app.

7.Share app, then they can share and save lives.
