The short answer
ZoopCoder fixes one reproducible bug or crash in an existing Android app for a fixed ₹1,299 per issue, with the code diff and a signed build back in your hands in 2-3 working days. The price covers reproducing the issue on a real device, tracing the cause and making the smallest change that fixes it — not a rewrite, and not new features. Bring the stack trace if you have one: Play Console groups crashes and ANRs into clusters under Android vitals for every release, and a single cluster usually names the exact class and line, which is why a crash with a trace is often a one-day fix while "it hangs sometimes" has to be reproduced first.
What you get
- A build environment set up for your project, so the app compiles from your source before anything is changed
- The issue reproduced on a real Android device, or a written explanation of why it cannot be reproduced
- Root cause traced from the stack trace, Logcat or the Play Console Android vitals cluster
- The fix written in your own source code as the smallest change that solves it
- The exact code diff, so your own developer can read and keep what changed
- A signed release AAB and a debug APK built with your keystore and returned to you
- Retest on the device the bug was reported on, plus one older Android version
- Up to 2 rounds of revisions if the same issue is still not fixed

What we need from you
- The app source code, or a repository invite
- Steps to reproduce, a screen recording, or the crash stack trace from Play Console
- Your signing keystore and its passwords if you want a signed release build back
- Any API keys, test logins or backend access the app needs in order to run
Not included
- New features, screen redesigns and SDK or Gradle version upgrades — quoted separately
- Apps with no source code; a decompiled APK is not source and we will not work from one
- Publishing the fixed build to Google Play (app update release is ₹999)
- Backend or server-side faults that merely surface in the app — quoted after diagnosis
- iOS-only bugs, which need their own quote
- Play policy rejections and suspensions, which are separate services (₹2,999 and ₹3,999)
- targetSdk upgrade work Google is asking you for, which is a separate service (₹2,999)
About this service
This is deliberately the smallest honest unit of app work: one bug, one price, your code back. It exists because the usual alternatives are both bad — posting a single crash as a freelance project and waiting three days for bids, or paying a monthly retainer for an app that needs one afternoon of attention a quarter. We ask you to describe the bug before you pay, because a real share of what people call an app bug turns out to be a backend response, an expired API key, or a Play policy rejection wearing a bug's clothing, and none of those are fixed by editing the app. If that is what yours is, we will tell you and point you at the right thing instead of taking the order. Two limits are firm. We need real source code: a decompiled APK is not source, and patching smali is how apps end up unsignable and unpublishable. And the fix is scoped to the issue you reported — if fixing it uncovers that the screen needs rebuilding, we quote that separately rather than quietly doing it and calling it a bug fix. If you have a list of fifteen things wrong, do not buy fifteen of these; send the list and we will quote the batch, which will cost you less.
Questions before you buy
What counts as one issue?
One reproducible fault with one cause — a crash on a screen, a button that does nothing, a payment that fails, an image that never loads. If two symptoms turn out to share a single root cause, that is still one issue and we do not charge twice.
What if you cannot reproduce it?
We tell you what we tried, on which devices and Android versions, and what we need from you — usually a screen recording, the device model or a test account. If it genuinely cannot be reproduced and cannot be traced from a stack trace, we refund rather than bill for guesswork.
Do you need my source code?
Yes, always. We fix the bug in your project and hand back the diff so you keep the change. We do not work from decompiled APKs — that produces builds you cannot sign or update.
Will you upload the fixed app to Play Store for me?
Not in this price. Publishing an update is a separate ₹999 service, mainly because it needs Play Console access and a release note rather than developer time.
Can you fix a Flutter or React Native app?
Yes. Both are covered for the Android side. If the same bug also has to be fixed and verified on iOS, that needs a separate quote because it needs a Mac build and a separate test device.
My app was rejected by Google. Is that a bug fix?
No. A policy rejection is answered with a policy change or a declaration, not usually with code, so it is a different service (₹2,999). If Google rejected the app for crashing on launch, that part is a bug fix and this is the right product.
