What we build with Android

Android app development is how we put your product on the phones, tablets and wearables most of the world uses. We write native apps in Kotlin, with Java where older code requires it, and follow current Android architecture guidelines.

We handle the details that trip teams up on Android: many screen sizes, battery limits, background work and fragmented OS versions. That makes us a good fit for apps with calling, location or offline needs.

Technology we work with

  • Kotlin
  • Java
  • Jetpack Compose
  • Android SDK
  • Coroutines
  • Room
  • Firebase
  • Retrofit
  • Linphone SDK
  • WebRTC

Why Driansh

Why teams choose Driansh for Android

Background calling know-how

We build around Android's battery and background rules, so calls and alerts still arrive.

Built for real networks

We design for weak signals and offline use, so your app still works on the move.

You own the code

Source code, signing keys and Play Console access stay with you, so you are never locked in.

Room to grow

Clean architecture and modules make it easy to add features or an iOS version later.
