Android 17 Without the Last-Minute Scramble

Read on codenameone.com

Summary

CodeName One prepared for Android 17 (API 37) by addressing platform changes proactively, including fixing version number parsing and implementing the new system-rendered location button. They also added robust PEM key parsing and explicit task removal to simplify common security operations for app developers.

  • Proactive platform readiness involves compiling, assembling, and running apps against new SDKs to catch regressions early.
  • Android 17 introduces a system-rendered location button for transactional precise-location access, requiring `USE_LOCATION_BUTTON`.
  • CodeName One implemented the location button using reflection and Java proxies to avoid forcing AndroidX upgrades on users.
  • New security APIs simplify PEM key parsing, handling various formats and rejecting malformed or unsupported inputs.

This article offers valuable insights for mobile platform developers on managing complex SDK upgrades and integrating new OS features without forcing toolchain migrations.

  2. We Stopped Waiting for Platform Changes to Find Us

    Codename One added a daily automated scan of Apple and Google deprecation notices, linking each notice to concrete builder artifacts before work is created. The system caught the Android 16 back‑gesture change and enabled a permission‑free ContactPicker, turning policy shifts into repeatable, evidence‑backed patches.

  4. App Hardening: One Obfuscation Pipeline Across Every Port

    Codename One adds a cloud‑side hardening step that runs on the merged JAR before it is split into Android, iOS, JavaScript, and desktop binaries. It can rename symbols, encrypt string literals, and insert opaque‑predicate control‑flow guards at configurable levels (off → standard → aggressive → paranoid). The transforms are selective per platform to avoid breaking optimizers, and a mapping is kep…

  5. App Intents: One Java Declaration for Siri, Spotlight, and Shortcuts

    Codename One adds @AppIntent annotations that let a static Java method be exposed as a Siri, Spotlight, or Android shortcut. The build‑time processor generates native declarations, a reflection‑free dispatch table, and validates the intent metadata. Handlers can be headless, accept typed parameters, return results, and be invoked internally via Intents.invoke(). Entities enable system‑driven disa…

  6. SQLite Across Every Port: One Contract, One Encrypted File Format

    Codename One now ships a single, tested SQLite contract that works natively on Android, iOS, Windows, Linux, and in browsers via WebAssembly, with built‑in SQLCipher‑4 encryption supporting three key models. A conformance suite guarantees identical behavior across platforms, and migration helpers let legacy apps opt‑in. The update also adds a proper watch‑app model, DOM‑based text for JavaScript,…
