SOS App for Android

Inspiration

Was watching Aditya's stream on using GPS and Geocoding API with Xamarin. Figured we could make it in Java as well.

What it does

Whenever an user clicks on the SOS button, send coordinates to backend which then sends an SMS to people close to the user.

How we built it

Used Netlify Cloud Functions to run a serverless function, used geocoding API to get a formatted address and Twilio to send the SMS.

Challenges we ran into

Making an HTTP request with Java - Used Retrofit in the end.

Accomplishments that we're proud of

It works as intended!

What we learned

Working with Geocoding API and about concurrency and permissions in Android.
