LinkTrail Android SDK 0.1.0

Install it with:

implementation("io.linktrail:sdk:0.1.0")

⚠️ Breaking change

handleDeepLink now claims only LinkTrail links: *.linktrail.io plus the hosts you list in linkDomains. If you use a custom link domain, add it to linkDomains, or those links won't be handled.
- URLs that aren't LinkTrail links (your own myapp://, OAuth callbacks, mailto:) now return false, and the SDK makes no network call for them.

Later consent: granting consent after a denial now routes the deferred link.
Denied installs: they send no device id and no idempotency key.
An explicit denial always wins: setConsent(false) takes effect even with requireConsent = false.
Events in flight: an event already being sent when consent is denied is never sent.
SDK state stays on the device: it's excluded from backup and restore, so a restored or new phone counts as a new install.

Deferred link delivered at least once: it's saved until onLink receives it, even if onLink is registered late. It expires after 7 days.
Event queue:
- only retryable failures are queued;
- only one flush runs at a time;
- a corrupt entry no longer wipes the queue;
- cancellation is handled correctly.
configure: it's a safe singleton, and invalid options are clamped with a warning instead of throwing.
Device id: it's created once, even when several first calls race.

SDK header: every request sends X-LinkTrail-SDK: android/0.1.0.
Logs: log lines are unified with iOS (see LOGS.md).
Debug-only overrides: LINKTRAIL_BASE (backend URL) and debug.linktrail.referrer (install referrer) work in debuggable apps only.
