Fix App Crashes and Slow Response Times with Firebase

Once we deploy an android app to production, its common to see our users complain about crashes, device incompatibility issues and/or slow response times. Tracking down each and all of these problems can be time-consuming and require a lot of effort from our side. But what if we could automate part of this monitoring process? During this presentation, I spoke about the Firebase tools and services that can help developers monitor their android app releases.

Firebase and Kotlin: Extensions, Coroutines and Flows

I'll be speaking at Droidcon EMEA 2020 about Firebase and Kotlin. Full abstract: Android is now Kotlin-first, but most of the existing libraries and SDKs were written in Java. Despite the effort that the Firebase team has put in coming up with KTX libraries for their Android SDK, there are still a few Kotlin features that have been missed out. In this session, Rosário will talk about some of the features that are present in the KTX libraries and the features that you can implement yourself to get cleaner and more idiomatic Kotlin code. You’ll learn how Sequences, Sealed Classes, Coroutines and Asynchronous Flow can provide you with a kotlin-first experience when working with Firebase’s Android Java SDK.

Firebase on Android

When developing apps, Android Developers may need to spend some time building infrastructure for their apps and managing different tools. But what if we could save this time and use pre-existing infrastructure in a single and unified platform?In this talk, Rosário gives a quick overview of what Firebase is and how it simplifies the android app development process.We take a look at how to use Firebase Authentication to authenticate users into our app and how to store our user data in Cloud Firestore.
