Built for Google Play's Current Requirements
Google Play changes its rules every year, and apps that fall behind get blocked from updates. Our developers keep your app compliant:
Target API level
Google Play requires new apps and app updates to target an API level within one year of the latest major Android release. From 31 August 2025, that meant Android 15 (API level 35). (Google Play Console Help, "Target API level requirements")
Play Integrity API
to detect tampered apps and fraudulent devices.
Data safety declarations
that match what the app actually collects.
Permissions best practice:
photo picker, granular media permissions and runtime permission flows.
16 KB page-size support
and up-to-date native libraries for newer devices.
Kotlin or Java for Android Development?
Our recommendation: build new apps in Kotlin and Jetpack Compose, and migrate existing Java apps step by step. Kotlin and Java interoperate in the same project.
| Kotlin | Java |
|---|---|
| Google's position | Preferred language, "Kotlin-first" since 2019 |
| Jetpack Compose | Required |
| Code length | Shorter, null-safe by design |
| Coroutines / modern async | Built in |
| Best for | All new Android apps |
