How Much Does It Cost to Update an Old Android App?

BrightRevamp Team8 Oct 20263 min read

There is no honest flat price for "updating an Android app", because two apps with the same target level can be very different amounts of work. Here is what actually moves the price, so you can judge any quote you receive.

What drives the cost

1. How old the project is

An app last touched two years ago is a short job. One last touched many years ago has to pass through several generations of Android, Gradle and library changes first.

2. Whether it builds today

A project that still compiles is the cheap case. A project with build errors, missing dependencies or abandoned libraries needs revival before the real update even starts.

3. Which libraries it uses

Retired support libraries, discontinued third-party SDKs and old networking, image or ads libraries each add work. A library that no longer exists has to be replaced.

4. Native code (C/C++ or .so files)

Native libraries need extra checks, including 16 KB page size support. A prebuilt library can only be rebuilt by its owner.

5. In-app purchases

If your app sells anything, the Play Billing Library version matters, and old billing code can need rewriting.

6. How much testing the app needs

Logins, payments, notifications, maps and file access all behave differently on newer Android versions and all need checking.

What does not change the price

  • How many screens the app has, if they do not need redesigning.
  • How long the app has been on Google Play.

How we quote

We do not publish a price list. After a free app check you receive one fixed price and a delivery date before any work starts. If the billing code needs rewriting, that part is quoted separately, before work starts.

What to send for a quick, accurate quote

  • The source code, as a GitHub invite or a zip file. We do not need your keystore, passwords or Play Console access.
  • A screenshot of the Play Console message, if you have one.
  • Whether the app sells anything inside the app.
  • Whether it has native .so files.

Frequently asked questions

Why do you not list prices?

Because the work depends on the code. A fixed price after seeing the project is more honest than a range that may not fit your app.

Is the app check really free?

Yes. You get the check first, then a fixed price and a delivery date, and you decide after that.

Do you need my keystore or Play Console login?

No. We work on the source code, and you upload the finished build yourself.
