android-compat: Room, WorkManager, location, sensors, services and Keystore - #6098
Conversation
…ystore Adds the Android APIs over their Codename One equivalents, the iOS location hints an imported manifest implies, and fixes Location.setAccuracy, which only ever stored NaN. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
GCM refuses a second encryption under one IV; service stop/unbind/stopSelf are judged in order with their start/bind; removed location and sensor listeners hear nothing more; SQLite waits for another thread's transaction instead of failing; Room observers and live queries follow AndroidX's threading; migrations are checked against the entity columns; WorkStore saves survive a cut-short write and are merged before the first enqueue. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Service request sets are atomic copy-on-write and survive a stopSelf that races a new start; a failed bind is forgotten; GCM refuses the last key and IV on init; an unreadable saved work queue loads as empty, never partial; the main thread does not busy-wait on another thread's transaction.

A destroyed service leaves no start request behind; a failed bind keeps a live binding's record; GCM records the key and IV at init; the main thread waits two seconds for another thread's transaction instead of failing. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Flutter vs Codename OneSame application, built both ways: Flutter's AOT compile of the gallery, and the identical Dart source transpiled to Java on Codename One. Lower is better for every metric, so a ratio above 1.00x means Codename One is ahead by that factor. android9 interleaved rounds; host load 0.86, 2.38, 1.73

Compute -- the VM workloads ( Not measured: iOS compute is not measured: a device build needs signed hardware, and on the simulator Flutter runs its JIT debug engine rather than AOT code.

…ompat-testing Resolves the conflicts with the Swing/JavaFX compatibility layers: the Keystore shims join ANDROID_JDK_SHIMS, the Room and WorkManager generators use the composed relocator, and RoomGeneratorTest runs its relocated app with a Codename One of its own so another test's Display cannot reach it.

Adds the Android APIs that imported Android applications use most and that
the compatibility runtime lacked, each over its Codename One equivalent:
_Implclasses (no annotationprocessor, no reflection) over a SupportSQLite runtime; migrations are
checked against the entity columns; live queries follow AndroidX threading.
LiveData queries, persisted queue; constraints go to
BackgroundWork.com.codename1.location, SensorManager overMotionSensorManager(rotation math rewritten from AOSP, Apache-2.0, inNOTICE).
IntentService,startForegroundas a
ForegroundService, notifications and channels as localnotifications; manifest
<service>entries generate their factory.SecureStorage(keychain / platform keystore).locationbackground mode areadded to
codenameone_settings.propertieswhen the manifest asks forlocation and the project doesn't set them.
Also fixes a core bug:
Location.setAccuracystored only NaN (inverted by anearlier cleanup), so
getAccuracy()answered 0 on every port; covered byLocationExtrasTest.Limitations are listed in the developer guide's Android chapter.
