Android is based on a Linux kernel and has layers on top written in C and Java.
However, Android apps span almost the entirety when it comes to frameworks,
programming languages, libraries, and other technologies.
Most employers today expect Android developers to know both Java and Kotlin
programming languages. Some want experience with Swift, Objective-C, C++, Go,
Node.js, Python, JavaScript, React, and others. They’ll also need to be able to
work with Jetpack Compose, Android Studio, Android SDK, and more.
However, as someone looking to hire a freelance Android engineer, you only
really need to worry about the technologies you are already using or are
planning to work with. If you are looking to build an app from scratch, consult
a general freelance Android developer to get advice and insight into how they
would proceed. For a full picture, book a 30-minute or hour-long consultation
session with a few Android freelance developers.
One thing to keep in mind: the hard, technical skills (e.g., Java, Android
Runtime Environment, Elastic Search) are important, sure, but so are the soft
skills. Remote freelance Android programmers should be adept at communicating,
have great self-motivation and autonomy, and be highly skilled in time
management. Developers should also possess top-notch analytical skills and
decision-making skills, as well as complex problem-solving skills and a solid
work ethic.
