Key Elements of a Strong Cover Letter
Start with your name, phone number, email, and LinkedIn or GitHub link so the recruiter can reach you quickly. Make sure the email looks professional and the links point to up-to-date samples of your work.
Begin with a concise sentence that explains why you want this internship and what you bring to the role. Mention the specific team or project if you can so your letter feels targeted and not generic.
Highlight Android skills like Kotlin, Java, and familiarity with Android Studio along with one or two project examples. Describe what you built, the problem you solved, and the measurable outcome or learning from the project.
End with a short summary of why you are a good fit and a polite request for an interview or next step. Provide availability and thank the reader for their time so your closing is courteous and actionable.
Cover Letter Structure
1. Header
Include your full name and contact details at the top, followed by the date and the employer's contact details. Keep this section simple so the reviewer can find your information at a glance.
2. Greeting
Address the letter to a specific person when possible, such as the hiring manager or team lead. If you cannot find a name, use a role-based greeting like "Dear Hiring Team" to stay professional.
3. Opening Paragraph
Open with a short sentence that states the internship you are applying for and why you are excited about the role. Add one line that connects your background to the company or project to show you've done basic research.
4. Body Paragraph(s)
In the first paragraph, highlight 1 or 2 technical skills and one project that demonstrates those skills in practice. In the second paragraph, emphasize transferable abilities like problem solving, teamwork, and eagerness to learn, and tie them back to the internship's responsibilities.
5. Closing Paragraph
Finish with a concise summary of your interest and a clear call to action, such as requesting an interview or stating you will follow up. Thank the reader for their time to leave a polite final impression.
6. Signature
Sign off with a professional closing like "Sincerely" or "Best regards" followed by your typed name. Optionally include your phone number and a link to your portfolio or GitHub under your name.
Dos and Don'ts
Do personalize each cover letter to the company and role by referencing a project or value that attracted you to the internship. Personalization shows genuine interest and improves your chances of standing out.
Do describe concrete projects with specific technologies and your role in them so the reviewer sees real experience. Keep descriptions short and focused on impact and learning.
Do match language from the job posting for key skills and responsibilities so your resume and letter read consistently. This helps screeners quickly identify that you meet core requirements.
Do show enthusiasm for learning and growth since internships are about development as much as output. Emphasize how you plan to contribute while expanding your skills.
Do proofread for grammar and clarity and ask a mentor or peer to review your letter before sending. Small errors can distract from your qualifications and lower perceived professionalism.
Don't repeat your entire resume in sentence form since that wastes space and can feel redundant. Use the cover letter to add context that your resume cannot convey.
Don't claim expertise in tools or languages you only tried once, because interviewers will ask details. Be honest about your level and focus on what you learned from each experience.
Don't use generic phrases that could apply to any role, as they do not help you stand out. Specific examples and a clear connection to the role are more persuasive.
Don't overshare personal details or unrelated hobbies unless they show relevant skills like teamwork or leadership. Keep the content professional and role-focused.
Don't send a one-size-fits-all letter without checking names, dates, and company details, because that signals low effort. Small personalization steps demonstrate care and attention.
Common Mistakes to Avoid
Being too vague about projects makes it hard for reviewers to judge your ability, so include brief specifics and outcomes. Even small metrics or clear learning points help your credibility.
Opening with a weak statement like "I am applying because I need experience" undercuts your value, so frame your need as a chance to contribute and learn. Show how the company benefits from your participation.
Listing only coursework without practical application can feel theoretical, so pair classes with projects or labs where you applied concepts. Recruiters prefer demonstrated practice over theory alone.
Ignoring the job description leads to missed keywords and misaligned emphasis, so scan the posting and mirror its priorities in your letter. This helps your application pass initial screens and reach a human reviewer.
Practical Writing Tips & Customization Guide
Include a one-line portfolio link under your header that goes straight to your best Android project and a short README. A focused example saves time for recruiters and highlights your strengths quickly.
If you have limited Android apps, describe a relevant side project or school assignment and what you specifically built or fixed. Explain your contribution in terms of code, design, or testing to make it concrete.
Keep your tone confident but humble by framing achievements as what you learned and how you will apply that knowledge. This balances competence with coachability, which is ideal for interns.
Use active verbs like built, tested, debugged, and improved to describe work on projects, and avoid passive phrasing that obscures your role. Clear action words make your contributions easier to assess.
Cover Letter Examples
Example 1 — Recent graduate (Android internship)
Dear Ms.
I am a recent Computer Science graduate from State University with a 3. 7 GPA and two Android projects on Google Play with a combined 4,500 downloads.
In my senior capstone, I built a Kotlin app that reduced image load time by 40% using lazy loading and OkHttp, and I wrote unit tests that raised code coverage from 52% to 78%. I’m eager to join Nova Apps this summer because your work on location-based accessibility tools aligns with my senior project, which used Room, Retrofit, and the Google Maps SDK.
I can contribute by writing maintainable Kotlin, improving test suites, and shipping user-focused features within sprint cycles. I am available June–August and can start immediately.
Thank you for considering my application; I’d welcome the chance to discuss how my app experience and testing focus can help Nova Apps hit its roadmap milestones.
What makes this effective: specific metrics (downloads, GPA, % improvements), named tools, alignment with the company product, and clear availability.
Example 2 — Career changer (from web to Android internship)
Dear Hiring Team,
After three years building customer portals with React and TypeScript at FinCo, I’m shifting to mobile to deepen my front-end skills on Android. I led a feature that increased portal sign-ins by 18% by redesigning the auth flow and writing A/B tests.
To prepare, I completed a 12-week Kotlin course and published a side project that syncs local notes with a cloud API using WorkManager and Coroutines.
I admire BrightPhone’s focus on privacy-first messaging and want to contribute by applying my UX-first approach to Android UI and by improving app reliability. I learn quickly; in my last role I reduced bug-report turnaround time from 6 days to 2 by instituting a triage checklist.
I’m seeking a paid internship where I can pair with senior Android engineers, write unit and UI tests, and help ship polished user experiences.
What makes this effective: demonstrates measurable impact in prior role, shows concrete upskilling steps, and explains how web experience transfers to mobile.
Example 3 — Experienced professional seeking an internship to reskill
Dear Mr.
I’m an embedded systems engineer with five years at MedDevices Inc. , and I’m applying for the Android internship to transition into mobile health app development.
At MedDevices I reduced firmware boot time by 30% and collaborated with clinical teams to deliver features that passed FDA software audits. Last year I completed an Android Nanodegree and built a health-monitoring app that collected sensor data and maintained battery use under 6% per day on average.
I offer system-level thinking, experience with Bluetooth LE, and a disciplined QA process. I want to join HealthWave to combine medical-device safety practices with user-centered mobile design.
During the internship I aim to contribute by improving BLE reliability, writing instrumentation tests, and documenting regulatory-relevant design decisions.
What makes this effective: highlights domain expertise, quantifies past improvements, and ties regulated-software experience to mobile health needs.
