AndroidTracker

This project is an example backend for the open source Self Hosted GPS Tracker Android application. You can download the Android app on the Play Store.

The application can be deployed to heroku and provides a realtime map view. It also stores all the locations in postgres.

Deploying

This is a Phoenix application so you can mostly follow their guide except for a few tweaks. I'm going to lay out the steps here:

• Make sure you have a heroku account and a working install of heroku toolbelt
• Create your heroku app (you can put a name after create for a custom name heroku create myappnam --buildpack.....)

$ heroku create --buildpack "https://github.com/HashNuke/heroku-buildpack-elixir.git"
Creating mysterious-meadow-6277... done, stack is cedar-14
Buildpack set. Next release on mysterious-meadow-6277 will use https://github.com/HashNuke/heroku-buildpack-elixir.git.
https://mysterious-meadow-6277.herokuapp.com/ | https://git.heroku.com/mysterious-meadow-6277.git
Git remote heroku added

• Add the phoeinix static buildpack:

$ heroku buildpacks:add https://github.com/gjaldon/heroku-buildpack-phoenix-static.git
Buildpack added. Next release on mysterious-meadow-6277 will use:
  1. https://github.com/HashNuke/heroku-buildpack-elixir.git
  2. https://github.com/gjaldon/heroku-buildpack-phoenix-static.git
Run `git push heroku master` to create a new release using these buildpacks.

• Add the postgres hobby addon

 heroku addons:create heroku-postgresql:hobby-dev

• Generate a secret

$ mix phoenix.gen.secret
xvafzY4y01jYuzLm3ecJqo008dVnU3CN4f+MamNd1Zue4pXvfvUjbiXT8akaIF53

• set SECRET_KEY_BASE config variable

heroku config:set SECRET_KEY_BASE="xvafzY4y01jYuzLm3ecJqo008dVnU3CN4f+MamNd1Zue4pXvfvUjbiXT8akaIF53"

• Set your hostname to the heroku hostname you created in step 1

heroku config:set HOSTNAME="mysterious-meadow-6277"

• Run the database migrations

heroku run mix ecto.migrate

Configure Android App

When you open the app on your phone you are asked to enter a server url. Enter:

https://mysterious-meadow-6277.herokuapp.com/update

where mysterious-meadow-6277 would be your hostname
