Day 1 on the Android Developer path.

What a Android Developer does

Builds and improves apps for Android phones, tablets, and watches so users get fast, reliable screens that follow Google's design and store rules. Focuses on one platform in depth, unlike a general mobile developer who splits time across both Android and Apple devices.

  • Build app screens and flows with Jetpack Compose, Google's modern Android user interface (UI) toolkit
  • Write features in Kotlin using the Android software development kit (SDK)
  • Connect apps to web services and local storage to load and save data
  • Test on many Android phones and screen sizes to catch crashes and bugs
  • Profile memory, battery, and start-up time to keep the app smooth
  • Configure Gradle build files, app signing, and version settings for releases
  • Submit and update builds on the Google Play store and read crash reports
  • Work with designers and product teammates to plan and estimate features

A day in the life

  1. Check messages and crash reports, then plan a small set of tasks
  2. Build a feature in Android Studio and run it on an emulator
  3. Test the same screen on several real devices to spot layout issues
  4. Join a short team sync to unblock work and confirm requirements
  5. Review a teammate code change and update yours from the feedback
  6. Prepare a signed build and push a release to Google Play
