Starting out as an Android developer

I have just graduated and officially started my journey towards becoming an Android developer. Wanting to build apps that are simple but genuinely useful, I finished a couple of personal projects.

VideoPlay

An offline video player that reads from device storage — light, smooth and easy to use.

Features:

  • Scans and lists the videos on the device
  • Play, pause and seek
  • Full-screen, minimal interface
  • Supports Android 6 and above

Built with Java, MediaPlayer, VideoView, and storage permission handling.

Source code on GitHub

Excel Reader

An app that reads and displays the contents of Excel files (.xls, .xlsx) directly on an Android device.

Features:

  • Pick an Excel file from storage
  • Parse and display the contents of each sheet
  • Handles a range of data formats

Built with Kotlin, Jetpack Compose, Apache POI and MVVM.

Source code on GitHub

What I am focusing on

  • Jetpack Compose
  • Clean Architecture
  • Android lifecycle and performance
  • Working with APIs, file I/O and media

I am looking for a chance to learn in a real production environment, and I am ready to put the work in. If you work in Android or have advice for a junior, I would love to connect.
