Android App Development in Surabaya
Android apps that keep working when the signal does not, built for the range of phones people actually own.
Android projects are planned around the constraints of the device: what has to work with no connection, what must keep running when the screen is off, and how the app gets onto phones. Those three answers shape the architecture more than any framework choice.
Both apps below are on Google Play. Laras keeps lessons usable offline with progress synchronised once the device is back online, and also ships APK builds for arm64-v8a, armeabi-v7a and x86_64. Kasir Kaki Lima is a Flutter point-of-sale app for small businesses that keeps transactions, stock and customer credit in a local database and synchronises with Supabase.
What you receive
- Release APKs per CPU architecture, with notes on which build suits which device
- Local-first data storage with a defined synchronisation strategy
- Foreground service and notification setup for work that must continue in the background
- A privacy policy and account deletion page when the app handles user accounts
Frequently asked questions
How much does an Android app cost in Surabaya?
A simple app of about 10 screens with one user role is Rp 5 – 20 million over 2 – 6 weeks. An app with several roles, offline mode with synchronisation and reports is Rp 20 – 60 million over 1 – 3 months.
Can the app be published on Google Play?
Yes. The Google Play developer account costs USD 25 once and is registered in your name. Apps for internal use can also be shared directly as APK files.
Can the app work without internet?
Yes. Data is stored on the phone first and synchronised when the connection returns. Kasir Kaki Lima and Laras, both on Google Play, work this way.
