Android Architecture Components – Looking at ViewModels – Part 2

The Android Architecture components were recently announced at Google I/O 2017. There are a few different components that are a part of these libraries. These components can be used in isolation but work really well when used together. In the previous blog post, we looked at using Room and LiveData. Make sure you read that post before this one, as this is a continuation. Continue reading Android Architecture Components – Looking at ViewModels – Part 2

Android Architecture Components – Looking at Room and LiveData – Part 1

This week at Google I/O 2017, there were a lot of new announcements for the Android Platform. One of the announcements was the new architecture guidelines for Android! This is a welcome addition to the Android platform.

Previously the Android team refrained from giving advice as to how you should structure your Android applications. For the most part this meant that anyone learning Android for the first time would just end up placing all their code into the Activity files and occasionally moving stuff into an AsyncTask if the app crashed with a NetworkOnMainThreadException. Only after trying to add unit tests and instrumentation tests would you really understand that your code you have just spent so long developing was not easy to read, make changes to or to write tests for.

Speaking at the App Builders Conference in Switzerland – 2017

Speaking at App Builders Switzerland this past week on Android Things was an invaluable experience, I had such a fantastic time. Besides the conference, I got to do a bit of sightseeing. I was able to take a day to explore Zermatt and experience a lot of snow! Unfortunately the Matterhorn wasn’t visible but this didn’t really bother me as I had enough fun exploring the snow topped mountains anyway.

Electricity Monitoring App – Send Push Notifications using Firebase Cloud Functions

This week Firebase launched a new and VERY exciting feature called Firebase Cloud Functions. It makes Firebase even more powerful than before, by allowing you to trigger functions when certain events happen. Events can be any of the following things:

  • Data changes on Firebase Realtime database nodes.
  • Authentication Changes
  • Analytics Changes
  • Cloud Storage Changes
  • and a few more…

Cloud Functions is a hosted, private, and scalable Node.js environment where you can run JavaScript code.

Android Things – Electricity Monitoring App

For those who may not know, I live in beautiful sunny South Africa (see my tweets for lots of awesome pictures). A few years ago we battled with a lack of electricity. While “load-shedding” is not so common these days, we have numerous unplanned outages. We even have a few of apps that give out schedules when the electricity is scheduled to go off in your area (see here and here).
