Android Developer Resume Example (Kotlin & Java)
On this page

Recruiters screening Android roles look for one word before anything else. That word is Kotlin. The language shift away from Java is the single biggest reason a strong Android developer resume from five years ago now fails keyword filters, because postings that once asked for 'Java, Android SDK' now ask for Kotlin, Jetpack Compose, Coroutines, and Hilt, and an applicant tracking system (ATS) matching against that list does not infer any of it from your Java history.

This guide walks through a complete Android developer resume example built for the current market, then shows how to adapt it for Java-heavy legacy roles. Along the way you will see how to quantify the app metrics mobile hiring managers actually trust, and how to list the Jetpack stack so both the software and the human reading after it find what they need.

Crafting an Android developer resume for modern ATS

An ATS does two jobs with your resume. It parses the document into structured fields, and it lets a recruiter search the result by exact strings. Both jobs punish Android developers in particular, because our stack is full of terms with more than one name. A recruiter filtering on 'Jetpack Compose' will not surface a resume that only says 'Compose,' and a filter on 'Hilt' does not match 'Dagger' even though every Android engineer knows how the two relate.

That is the frame for every formatting decision below. You are writing for a parser and for a seven-second human skim before any engineer reads a word.

  • Use standard section headings like 'Experience' and 'Skills' so the parser maps each block correctly. Clever labels like 'What I've Shipped' confuse field mapping.
  • Spell out full terms at least once. 'Kotlin Coroutines' and 'Jetpack Compose' survive keyword filters; a bare 'coroutines' often does not.
  • Put your stack inside experience bullets, not only in the skills list. A keyword attached to a shipped feature reads as evidence; a keyword in a comma-separated line reads as a claim.
  • Mirror the job title. If the posting says 'Android Engineer,' use that phrase in your headline rather than 'Mobile Developer,' because title matching is one of the first things a screen checks.
  • Export as a PDF with selectable text. A clean single-column or well-structured two-column layout parses fine; text baked into graphics does not.

These mechanics apply to every engineering resume, and the longer treatment in our guide to building an ATS-friendly software engineer resume covers them in depth. What is specific to Android is the vocabulary, and that is where most resumes written before the Kotlin shift quietly fail.

Android developer resume example (Kotlin focus)

The example below shows a mid-level Android developer, about five years in, applying to product companies. Two decisions carry the document. The most impressive quantified win, a stability improvement measured in crash-free sessions, sits in the top bullet where a skimming recruiter cannot miss it. And the modern stack, Kotlin with Compose, Coroutines, and Hilt, appears inside the work itself rather than only in a skills list at the bottom.

Read this Android developer resume sample as a template for structure, not for copying. Your own numbers and your own migration stories are what make the same skeleton convincing.

Android Developer | Kotlin, Jetpack Compose & Coroutines — Resume example for a android developer, built on the ATS Minimal template.

The headline and summary

The headline mirrors the job title the candidate is applying to, with 'Android Developer' spelled out. Under it, the summary makes three moves in as many lines. Years of experience and the core language come first, because 'Kotlin' in the opening line is exactly what a recruiter's eye is scanning for. A named specialty follows, in this case Compose migration and app stability. The final line carries one number, which does more to establish seniority than any adjective could.

Skip the objective statement at this level. A summary states what you have done, an objective states what you want, and a recruiter filtering two hundred applicants only cares about the first.

Experience bullets that carry the stack

Every strong bullet in the example follows the same skeleton without sounding formulaic. An action verb opens it and a measured outcome closes it, with the specific technology named in between. 'Migrated the checkout flow from XML Views to Jetpack Compose, cutting UI code by roughly a third and eliminating a class of state bugs' tells a hiring manager more than a paragraph of responsibilities ever could.

Notice what the bullets avoid. There is no 'responsible for maintaining the Android application' and no technology named without something it was used to build. Scope beats duties at every level of seniority, and on a mobile resume scope means users and measurable app health.

Skills and projects

The skills section is grouped and short, with every term written the way postings write it. Grouping shows judgment. A flat list of twenty-five technologies says you typed everything you ever touched; five labeled groups say you know how the pieces relate.

The projects section earns its place with a published app and real adoption figures. For a mid-level developer a projects section is optional. For a junior it is the whole argument. Either way, a Play Store link a hiring manager can tap outweighs three unverifiable bullets, and our guide to listing coding projects on a resume covers how to present a small app without it looking trivial.

Adapting the example for Java and legacy Android roles

Not every Android role is a greenfield Compose app. Banks and insurers, device manufacturers, government contractors, and agencies maintaining client portfolios all run codebases that predate the Kotlin shift, and their postings read differently. Java appears as a requirement rather than a footnote, and XML Views are still the daily reality. RxJava often sits beside Flow in the same posting because the codebase is mid-migration.

You do not need a second resume so much as a reweighted one. Start from the same skeleton as the example above and shift the emphasis.

  • Move Java up. In the skills groups and in the summary, 'Java' should be visible in the first line, beside Kotlin rather than behind it.
  • Lead with a migration story if you have one. 'Converted the payments module from Java to Kotlin across four releases with zero regression incidents' is the single most valuable bullet for a legacy-heavy team, because it proves you can modernize without breaking production.
  • Show interop fluency. Mixed codebases live and die on Kotlin-Java interop, so a bullet about working across both languages in one module signals more than either language alone.
  • Keep RxJava if you have it. Many teams are converting Rx chains to Flow and want someone who can read both fluently.
  • Do not write a Java-only resume. Even the most conservative postings now expect Kotlin, and a resume without it reads as five years out of date.

Kotlin vs. Java: what job descriptions actually ask for

Google named Kotlin the preferred language for Android development back in 2019, and the job market has finished catching up. Scan a page of current Android postings and the pattern is consistent. Kotlin is a hard requirement almost everywhere. Jetpack Compose has moved from nice-to-have to expected for product roles, helped by the fact that Compose is Kotlin-only. Java, when it appears, is usually attached to a phrase like 'experience with legacy codebases' or listed second, as interop knowledge rather than a primary language.

The practical consequence for your resume is ordering. Kotlin belongs in your headline and inside your top bullets, and it goes first in the languages group. Java stays on the page, because filters still match it and mixed codebases still need it, but it should read as a competency you carry rather than the identity of the resume.

An interviewer points to a circled technical skill on a candidate's resume during an Android developer interview.
Skill or keywordWhat it signals in a postingHow to handle it on your resume
KotlinDefault language for new development; expected in nearly every modern Android roleName it in your headline and inside experience bullets, not only in the skills list
JavaLegacy maintenance, enterprise codebases, or interop workKeep it listed, and pair it with a migration or interop story when the posting emphasizes it
Jetpack ComposeThe team is building or migrating to declarative UISay plainly if you have built production screens in it or migrated XML to it; both count
XML layouts / ViewsAn older codebase, with migration work likelyDo not delete it; hybrid codebases need people fluent in both worlds
Kotlin Coroutines / FlowModern async and reactive patterns are expectedShow it in a bullet with a concrete outcome, like replacing callback chains or an RxJava migration
RxJavaLegacy reactive code, often mid-migration to FlowKeep it listed; teams converting Rx want someone who reads both
Hilt / DaggerDependency injection at scale, usually a larger modular codebaseName the exact one you used; filters match 'Hilt' and 'Dagger' as separate strings
MVVM / Clean ArchitectureThe team has architecture standards and wants proof you have worked within themMention the pattern inside a bullet describing a real module, not as a floating buzzword

One caution on formatting. Writing 'Kotlin/Java' as a single slashed token can defeat exact-string matching in stricter systems. List them as separate terms and let each one be findable on its own.

How to quantify app performance, crashes, and downloads

Mobile is the easiest engineering discipline to quantify, because Google measures your app for you. Play Console tracks Android vitals, crash and ANR (application not responding) rates, install numbers, and ratings. Firebase Crashlytics reports crash-free session percentages per release. If your resume says 'improved app performance' with no number attached, a hiring manager assumes the number was not worth stating.

Pull the figures before you write. Ten minutes in Play Console and Crashlytics will hand most Android developers several resume-ready metrics they forgot they earned.

MetricWhere to find itWhat a strong bullet looks like
Crash-free sessionsFirebase CrashlyticsRaised crash-free sessions from 98.4% to 99.8% over three releases by resolving the top ten Crashlytics issues
ANR rateAndroid vitals in Play ConsoleCut the ANR rate below Play's bad-behavior threshold by moving disk and network work off the main thread with Coroutines
Cold start timeMacrobenchmark and Android vitalsReduced cold start by 40% using Baseline Profiles and deferred dependency initialization
App sizePlay ConsoleShrank download size by a third through App Bundles and R8 tuning
Downloads and ratingsPlay ConsoleShipped a redesigned onboarding flow that lifted the Play Store rating from 4.1 to 4.5 within two release cycles
Feature adoptionProduct analyticsLaunched in-app onboarding that raised day-7 retention by 12%
Build and release speedCI dashboardsCut CI build time in half by splitting the app into feature modules

Two rules keep these numbers safe. First, only claim figures you can walk through in an interview, because a good mobile interviewer will ask how the improvement was measured and what the baseline was. Second, when you cannot recover the exact figure, state the relative change and the mechanism instead. 'Roughly halved cold start by deferring SDK initialization' is honest and still concrete; a suspiciously precise number you cannot defend is worse than none at all.

Listing Android Jetpack, Coroutines, and Dagger/Hilt

The Jetpack ecosystem creates a specific resume problem. There are dozens of libraries, and recruiters filter on a handful of exact names. A laundry list of every dependency you have ever imported dilutes the terms that matter. Group your skills and keep each group short. A structure like this works for most Android developers:

An overhead view of a printed resume with generic skills crossed out and modern Android technical terms written in blue ink.
  • Languages (Kotlin, Java)
  • UI (Jetpack Compose, XML Views, ConstraintLayout, Material 3)
  • Architecture and DI (MVVM, Clean Architecture, Hilt, Dagger)
  • Async and data (Kotlin Coroutines, Flow, Room, Retrofit)
  • Testing and tooling (JUnit, Espresso, Compose UI testing, Gradle, GitHub Actions)

Name Hilt and Dagger separately if you have used both, since filters treat them as different strings. The same goes for 'Kotlin Coroutines' and 'Flow.' And prune the dated signals. AsyncTask, ButterKnife, Eclipse, and the old support libraries mark a resume as pre-2019 even when everything else is current; the interview can cover your history, the resume should cover your present.

One more rule for the skills section. Everything in it is an invitation to be interviewed on it, so cut any term you would not welcome a follow-up question about. A shorter list you can defend beats a longer one you cannot.

Import your existing resume and update your stack

Most Android developers do not need a new resume. They need the vocabulary of an old one replaced and the metrics filled in, with the ordering flipped for a Kotlin-first market. That is an editing job, and the obstacle is usually that the old resume lives in a file nobody wants to rebuild from scratch.

Roleframe removes the retyping. Upload your current resume as a PDF and it comes back as editable blocks, with roles and dates and bullets in the right places, inside a document-grade editor whose PDF export matches the screen exactly. The import runs a full resume analysis on its own, so the first thing you see is a scored document with its weak sections named. From there the update pass is quick.

  1. Swap the vocabulary. Replace generic 'Android development' phrasing with the exact terms above, and make sure Kotlin and Jetpack Compose each appear where a filter will find them, in the summary as well as the bullets.
  2. Add the numbers. Open Play Console and Crashlytics, pull your crash-free rate and vitals figures, and rewrite the top bullets around them.
  3. Reorder for the market. Put Kotlin first in the languages group and move the strongest quantified bullet to the top of each role.
  4. Fix what the analysis flagged. Weak summary lines and duty-style bullets are the two most common findings on imported developer resumes.

Tailor your resume for specific mobile roles

'Android developer' means different jobs at different companies. A consumer product company weights Compose fluency and app-health metrics. An SDK or platform team cares about API design and binary size. An agency wants breadth across client codebases, which is where cross-platform experience and legacy Java both earn their place. One resume cannot lead with all of it, which is why a base resume with tailored versions per job beats a single document sent everywhere.

Titles vary too. Some companies post the same role as 'Mobile App Developer' or 'Mobile Engineer,' and your headline should mirror the posting's phrasing on that version, since title matching is part of what gets filtered. Guessing at the rest of the keyword gaps costs interviews. Paste the posting into Roleframe and the fit report scores your resume against that specific job, then lists the exact keywords the posting filters on that yours is missing. You make the edits yourself, with Remi, its career copilot, proposing rewrites bullet by bullet for you to approve, so every line stays something you can defend in the interview.

Frequently asked questions

Should I list Kotlin or Java first on an Android developer resume?

Kotlin first, in almost every case. It is the language postings require and the one recruiters filter on, so it belongs in your headline and at the front of your languages group. The exception is a posting that explicitly leads with Java, usually for a legacy enterprise codebase; mirror that emphasis for that application only, and keep Kotlin visible right beside it.

How long should an Android developer resume be?

One page through roughly eight years of experience, and two pages after that if the extra material is genuinely strong. Density beats length. A senior Android developer resume with twelve tight, quantified bullets outperforms a two-page chronicle of every project ever touched. Our breakdown of whether a resume should be one page or two covers the call by experience level.

What should a junior Android developer resume include with no work experience?

A published app, even a small one. A Play Store link with real installs proves you can ship through Play review and respond to real crashes, which coursework cannot. Build it in Kotlin with Compose, quantify what you can (downloads and crash-free rate), and lead the resume with a projects section rather than education. Recruiters screening juniors are looking for evidence of shipping, and a live app is the strongest evidence there is.

Should I put Play Store and GitHub links on my resume?

Yes, as clickable links in the header or the projects section. A hiring manager who can tap through to a live app or a readable codebase will often do it before deciding on an interview. Make sure the profile you link is presentable, with pinned repositories and a README on anything you name. Our guide on where to put your GitHub link covers the details.

Do I need Jetpack Compose on my resume in 2026?

For product company roles, effectively yes. Compose is the default for new Android UI, and postings treat it as expected rather than impressive. If your professional work has been XML-only, ship a small Compose app or migrate a screen in a side project so you can list it honestly. A migration bullet, even from a personal project, answers the question every Compose-era interviewer will ask.

Is Flutter or React Native worth listing on a native Android resume?

List it if the experience is real, in its own cross-platform group so it does not blur your native positioning. Native-first teams will not penalize the extra skill, and agencies actively value it. Just never let it displace Kotlin from the top of the page when the role is native Android.

Do Android certifications help?

Less than a shipped app, and far less than a quantified stability or performance win. A certification can help a career changer show commitment when there is no work history to point at, but no Android hiring manager picks a certificate over a Play Store link. If you hold one, list it in a short certifications section near the bottom and spend your effort on the experience bullets instead.
