Should you list non-core work experience on your resume?

Question

Android

In the near future I plan to get a job as an Android developer. Previous experience only in system administration. Do you think it makes sense in a resume for a developer to indicate work experience in other areas?

Answer 1

Remember, a resume for a specific job is specific skillsfor which they take you. These are the things employers need to know about.
Everything else - take out in the column " Additional skills ", " Other qualifications " or " I also know ". Well, be reasonable: do not write in extra. 20 points in skills, and 3 points in special ones for vacancies.

Answer 2

I indicated, otherwise you will be asked a question about what you did in a particular period of time that is not indicated in the resume. It’s just that I don’t describe non-core work in detail.
