Android compat: document intents via native file dialogs; iOS background execution guide by shai-almog · Pull Request #6130 · codenameone/CodenameOne

shai-almog · 2026-10-29T03:54:39Z

Addresses discussion #6127.

Document intents. `ACTION_OPEN_DOCUMENT`, `ACTION_CREATE_DOCUMENT` and non-media `ACTION_GET_CONTENT` threw `ActivityNotFoundException`. They now open `Display.showOpenDialog` / `showSaveDialog` and return through `onActivityResult` (activities and fragments) and the AndroidX contracts (`OpenDocument`, `OpenMultipleDocuments`, `CreateDocument`, `GetMultipleContents`; non-media `GetContent`). Adds `ClipData`, `Intent.get/setClipData`, `ContentResolver.openOutputStream(uri, mode)` and no-op persistable URI permissions.

`CREATE_DOCUMENT` cannot match Android on iOS, where the picker only exports an existing file: the app gets a staged file at once, and closing the stream it wrote shows the Save dialog. Documented in the class and the guide.

Guide. New "Opening and creating documents" and "Background execution on iOS" sections in `Android-Interop.asciidoc`, mapping foreground services, background location (already wired: manifest -> `location` background mode -> `allowsBackgroundLocationUpdates`) and WorkManager to iOS behaviour, with porting advice.

Tests: `DocumentIntentsTest` (8) on new `HeadlessImplementation` dialog hooks; android-compat suite 599/599, SpotBugs 0, cast-semantics clean.

ParparVM vs HotSpot (JDK 25): macOS arm64

Runner CPU: Apple M1 (Virtual) (baseline macos-arm64)

Ratios are ParparVM / JDK 25: below 1.00x ParparVM is faster (time) or smaller (RAM). Median of 5 interleaved, paired rounds; every run's output was verified. A ratio more than 20% (time) / 25% (RAM) above its baseline in vm/selfhost/perf-baseline/ is a regression and fails; one that far below is an improvement, reported but not failed (a row whose calibration runs were noisier carries a wider tolerance), and for RAM the change must also exceed 0.05x in absolute terms. Both run unpinned on all of the runner's CPUs, with their own default thread counts.
