Key Elements of a Strong Cover Letter
Start with your name, email, phone number, and a link to your portfolio or GitHub so the reader can find your work quickly. Include the hiring manager's name and the company address when you can, because personalization shows care.
Lead with a brief sentence that connects your background to the role and the company, so the reader understands why you applied. Use one strong sentence about a recent achievement to draw attention.
Summarize 2 or 3 relevant skills and a concrete achievement, such as improved app performance or user growth, with numbers when possible. Focus on outcomes you produced, not just the libraries or tools you used.
Explain why you want this company and how your working style fits their team, using specifics about their product or mission. End with a clear call to action, such as offering to share a code sample or schedule a call.
Cover Letter Structure
1. Header
Put your full name at the top, followed by your contact details and a link to your portfolio or GitHub. Add the date and the company contact information on the left to keep the layout professional and scannable.
2. Greeting
Address the hiring manager by name when possible, and keep the greeting short and polite to set a professional tone. If you cannot find a name, use the team name that matches the role, for example "Android Team" or "Hiring Team".
3. Opening Paragraph
Start with a concise hook that connects your recent work to the role, and mention the position you are applying for to avoid confusion. Follow with one sentence that highlights a relevant accomplishment to capture interest early.
4. Body Paragraph(s)
Use one paragraph to describe your top technical skills and a specific achievement, including metrics like crash rate reduction or download growth when available. Use a second paragraph to describe a project or problem you solved and how that experience will help you on this team.
5. Closing Paragraph
Wrap up by briefly stating why you want to join the company and what you can offer, and include a polite call to action to review your portfolio or schedule a conversation. Express appreciation for their time to keep the tone professional and courteous.
6. Signature
Sign off with a professional closing such as "Sincerely" or "Best regards" followed by your full name. Below your name, repeat one contact method or link so the recruiter can reach you easily.
Dos and Don'ts
Tailor each letter to the job posting and the company, and highlight matching keywords from the description. Personalized letters have a higher chance of getting read.
Quantify your impact with numbers, for example percentages for performance gains or user growth, to show real results. Concrete data makes achievements more credible.
Mention specific Android technologies and versions you worked with, such as Kotlin, Jetpack libraries, or architecture patterns, to show relevance. Match technologies to the job requirements when possible.
Keep the letter to one page with two to four short paragraphs, so the reader can scan it quickly. Short, focused letters respect the recruiter's time.
Proofread carefully and ask a colleague to review for clarity and tone, because small errors can hurt your first impression. A clean, error-free letter shows attention to detail.
Do not repeat your resume line by line, because the cover letter should add context and narrative. Use the letter to explain impact, not to list tasks.
Avoid vague statements like "I am a hard worker" without examples, because they do not show skills. Replace them with short stories of how you solved a problem.
Do not include unrelated personal details, because they distract from your qualifications. Keep the focus on work that matters to the role.
Do not exaggerate your role or results, because honesty builds trust and makes future conversations smoother. If asked, you should be able to explain any claim you make.
Avoid long technical dumps with no context, because recruiters may miss the impact. Explain why a technical choice mattered for users or the product.
Common Mistakes to Avoid
Opening with a generic sentence that could apply to any job, which makes your letter forgettable. Instead, connect your first line to the company or product to make it specific.
Forgetting to mention measurable outcomes, which makes achievements feel vague. Add one metric or result to show the scale of your contribution.
Using technical terms without explaining the impact, which can confuse nontechnical readers. Briefly tie tools or patterns to user or business outcomes.
Weak closings that do not invite next steps, which leave the reader unsure how to follow up. End with a clear offer to share more work or meet for a conversation.
Practical Writing Tips & Customization Guide
Include a short link to a relevant app or GitHub repo and point to a specific file or commit, because context helps reviewers find your best work. Mention one sentence about what they should look at in the sample.
If possible, reference a problem the company faces and state briefly how your experience relates, because this shows initiative and research. Keep it concise and respectful.
Use active verbs and keep sentences short to improve readability, because concise language reads better on screens. Aim for two to three sentences per paragraph.
Save your file name with your name and the role, for example "JaneDoe_AndroidDeveloper.pdf", so recruiters can keep it organized. A clear file name helps your application stand out in a positive way.
Cover Letter Examples
Example 1 — Career Changer (Web → Android)
Dear Hiring Manager,
After five years building Java-based APIs, I moved into Android because I enjoy building product surfaces users touch. At my last role I shipped a companion Android app that reached 50,000 installs in six months; I implemented offline sync with Room + WorkManager that cut failed syncs by 45% and reduced support tickets by 18%.
I wrote the app in Kotlin, introduced modularization to reduce build times by 30%, and added Firebase Crashlytics to lower the crash rate from 1. 8% to 0.
6% over three releases. I’m excited by your product’s focus on local-first apps; my background in data modeling and mobile UX will help you ship the upcoming offline-first features faster.
Thank you for considering my application — I’d welcome a short call to walk through the architecture and metrics I can replicate at Acme Mobile.
Why this works:
- •Shows measurable impact (installs, % reductions)
- •Highlights transferable backend skills and concrete Android tools
- •Ends with a clear next step

Example 2 — Recent Graduate
Hello Recruiter,
I recently graduated with a B. S.
in Computer Science and completed a 6-month Android internship at BetaTech, where I contributed to a student budgeting app that reached 5,200 active users. I built UI screens in Jetpack Compose, added unit tests (raising code coverage from 42% to 68%), and implemented in-app analytics that identified a drop-off point, allowing the team to increase 7-day retention by 12% after one redesign.
I’m comfortable with Kotlin, MVVM, Firebase, and Git-based workflows. I also maintain a personal app on the Play Store with 3,000 installs that demonstrates my work on accessibility and dark-mode support.
I’m eager to join your junior Android team to apply these hands-on skills and grow under senior engineers. I’m available for an interview any weekday afternoon.
Why this works:
- •Demonstrates concrete contributions and metrics
- •Balances learning mindset with practical experience
- •Provides availability and clear motivation

Example 3 — Experienced Professional (Senior Android Engineer)
Dear Hiring Team,
I’m a Senior Android Engineer with eight years building consumer apps. At MyApp I led a six-person Android team and delivered a major refactor that cut cold-start time by 60% and increased daily active users by 40% over three quarters.
I introduced a CI/CD pipeline (fastlane + Bitrise) that reduced release cycle time from 10 days to 3 days and enforced automated UI tests that caught regression-prone flows, reducing post-release hotfixes by 75%. I’ve designed payment flows integrating Stripe and handled GDPR-compliant data storage across regions.
I’m interested in your Senior Android role because of your multi-market expansion; I can help scale the app to new regions while keeping performance and compliance within budget.
Why this works:
- •Leadership and team-size details
- •Specific performance and process improvements with percentages
- •Connects experience directly to company needs
Actionable takeaway: Use concrete numbers, name tools/architectures, and close with how you’ll address the employer’s priorities.
Practical Writing Tips
1. Start with a focused opener.
Open with one sentence that states your role, years of experience, and the single achievement most relevant to the job — hiring managers decide fast, so lead with impact.
2. Use numbers to prove results.
Replace vague claims with metrics (downloads, % retention, crash rates). Numbers give recruiters tangible evidence of your contribution.
3. Match the job posting language.
Mirror three keywords or tools from the job description (e. g.
, Kotlin, Jetpack Compose, CI/CD) to pass ATS filters and show fit.
4. Show not tell with short anecdotes.
Describe one 2–3 sentence example where you solved a problem, the action you took, and the outcome — use the CAR (Context-Action-Result) format.
5. Keep paragraphs short.
Use 2–3 sentence paragraphs and bullets for lists; this improves scannability for busy reviewers.
6. Highlight teamwork and ownership.
Cite team size, your role, and decision-making scope (e. g.
, led 4 engineers, owned release pipeline) to show collaboration and leadership.
7. Be specific about tools and processes.
Mention libraries, testing approaches, and CI tools to demonstrate technical fluency without jargon.
8. Tailor one paragraph to the company.
Explain in 2–3 sentences why you want that company now and how you can address a stated challenge from their job post or recent news.
9. Close with a clear next step.
End by proposing a short call or interview window and thank them — concrete availability increases response rates.
10. Proofread for tone and clarity.
Read aloud or use a delayed review: cut passive phrases, remove filler words, and keep the tone professional yet conversational.
Actionable takeaway: Draft, cut to the top 3 achievements, and tailor the middle paragraph to each application.
How to Customize Your Cover Letter
Strategy 1 — Industry focus: tech vs. finance vs.
- •Tech: Emphasize product metrics, release cadence, and frontend trade-offs. Example: “Reduced app startup time by 60% and improved 30-day retention by 18% through view-layer optimizations.” Mention modern stacks (Kotlin, Compose) and app-scale issues like caching and offline UX.
- •Finance: Highlight security, compliance, and reliability. Example: “Implemented AES-encrypted local storage and wrote E2E tests to meet PCI compliance for 120k monthly transactions.” Mention audit experience and latency guarantees.
- •Healthcare: Stress privacy, data integrity, and accessibility. Example: “Built HIPAA-aware sync logic and AccessibilityService tests for screen readers.” Note clinical workflows and regulatory constraints.
Strategy 2 — Company size: startups vs.
- •Startups: Lead with breadth and speed. Show examples where you moved features from prototype to production in 2–6 weeks, owned releases, or built MVPs with small teams (1–3 engineers).
- •Corporations: Emphasize process, scale, and cross-team communication. Cite working with product managers, security teams, and multi-region rollouts (e.g., supported 2M users across three regions).
Strategy 3 — Job level: entry vs.
- •Entry-level: Focus on concrete learning outcomes and small wins. Mention internship metrics, capstone projects, and tests you wrote (e.g., boosted code coverage from 40% to 65%).
- •Senior-level: Stress leadership, roadmap contributions, and measurable team outcomes. Quantify team size, release frequency improvements, and cost or performance savings (e.g., cut CI time by 70%).
Strategy 4 — Concrete customization tactics
- •Echo company priorities: Pull one sentence from the job ad and respond directly (e.g., if they ask for offline-first experience, describe a sync strategy you built).
- •Prioritize three achievements: Rearrange your top three bullets so the most relevant appears first for that role.
- •Adjust tone: Use startup language (fast, iterative) for early-stage firms and more formal, process-oriented language for regulated industries.
Actionable takeaway: For each application, tweak one paragraph to cite a relevant metric, swap two keywords to match the posting, and end with a company-specific sentence about how you’ll solve a stated problem.
