The five stages
- Check. We read the code and build setup, find the target level, libraries, native files and billing, and list what has to change.
- Revive the build. If the project no longer compiles, we fix Gradle, repositories and dependencies first. See common build errors.
- Raise the target level. Update libraries and move to the current target API.
- Fix behaviour changes. New Android versions change layouts, back handling, permissions and background work. See the Elaaj case study for a real example.
- Test and hand over. Test on Android 16, then deliver a release-ready APK or AAB and a list of what changed.
What makes it quicker
- The app was maintained recently.
- The project builds today.
- Libraries are current or easy to move.
- You can send the full source and answer questions quickly.
What makes it slower
- The project has not been touched for several years.
- It depends on discontinued libraries that have to be replaced.
- It has native code or old billing code.
- The source is incomplete or missing files.
What you get before we start
After the free check you receive one fixed price and a delivery date. You are not guessing, and the date is based on your actual code.
Start early. Waiting does not make the update shorter. Each year adds another generation of changes for an old project to catch up on.
Frequently asked questions
Can you give me a number of days without seeing the app?
Not honestly. A recently maintained app is a short job and a very old one is not, so we give a date only after the free check.
Do I have to be available the whole time?
No. We work remotely on the source code and contact you only when a decision or a missing file is needed.
