Mobile applications are a huge industry and almost every business is relying on them. More than 70% of the market share belongs to Android and the competition between the top developers is huge. The high demand for Android developers these days leads to the logical question – how to evaluate and hire the best Android developer for your mobile app project? 

Finding an Android developer is not hard but hiring the best one might be a challenge. Especially if you are on a tight deadline, have a limited budget, or can not rely on an expert opinion from your team. 

Read on to find out everything you need to know about hiring an Android developer so that you can make a better and more informed decision. 

What level of seniority do you need from your Android developer? 

Depending on your project, a junior Android developer might be able to do the work, or you might need a more experienced professional. Evaluate the needs and requirements of the project before starting the hiring process to know exactly what you are looking for. 

Junior Android developers have less than 3 years of experience and can be engaged in the development of not complex apps. They can work as an assistant to middle and senior developers. 

Middle Android developers have more than 3 years of experience and can be engaged in complex Android-based projects. They can work independently.

Senior Android developers have more than 5 years of experience and can lead, supervise, and consult large projects. They occupy the team leader position. 

But no matter the seniority, an Android developer should possess strong technical expertise, be a team player, and a problem solver, and this is only the absolute bare minimum when it comes to skills.
