Small native Android share target for Instagram and Threads. Android 8+; no account, analytics, link history, or backend. This is an early debug build.
app/build/outputs/apk/debug/app-debug.apk.You can also paste a link into the launcher screen and tap Clean and share. Incoming shares skip the paste editor. One URL per share is supported; captions are discarded. No messages are sent automatically: choose the destination in Android’s share sheet.
All examples below are synthetic.
| Input | Handling |
|---|---|
instagram.com/p/POST_ID?igsh=REMOVED |
Preserve post path, remove all query parameters and fragment |
instagram.com/reel/POST_ID |
Direct post |
instagram.com/reels/POST_ID |
Normalize to /reel/ |
instagram.com/tv/POST_ID |
Preserve legacy post path |
instagram.com/share/p/TOKEN |
Online resolution required; also /share/reel/ and /share/r/ |
threads.com/@example/post/POST_ID?xmt=REMOVED |
Direct post; legacy threads.net also accepted |
threads.com/share/TOKEN |
Online resolution required; observed in the Android share sheet |
threads.com/t/POST_ID |
Online resolution required |
Unknown domains, unknown paths, profiles, stories, multiple URLs, userinfo, explicit ports and malformed addresses are rejected. All query parameters are removed, including optional carousel or presentation selections. The post author’s handle remains when it is part of the canonical address; this tool does not anonymize the post’s author or the content itself.
Short-link lookup follows at most five hops on an exact host allowlist within the original provider. It accepts recognized direct-post redirects or canonical/og:url HTML metadata. It does not execute JavaScript or sign in. Login walls, JavaScript-only redirects, rate limits and changed formats can prevent resolution. Real-world support must be verified against current links; synthetic parser tests do not prove a post exists.
Use JDK 17 and Android SDK 36. Set sdk.dir in an untracked local.properties, or configure ANDROID_HOME.
.\gradlew.bat :app:assembleDebug :app:lintDebug
.\test-parser.ps1
The app uses Android platform widgets and no runtime third-party libraries. The SDK and Gradle plugin are build dependencies. The debug APK is for development; distribution needs a release signing key.
Validation on 2026-09-06: debug assembly and Android lint passed (English-only string localization warnings remain); 24 synthetic parser checks passed. Installed over wireless ADB and verified a synthetic Instagram share reached the system share sheet without its tracking query. A user-selected public Threads /share/ link resolved to a recognized canonical post without a query using the same resolver on the desktop JVM. No live Instagram short-link lookup has been verified yet.
LinkCleaner contains pure Java provider rules; LinkResolver handles network resolution; MainActivity owns the share flow. Adding a built-in provider currently requires rebuilding the APK. A settings-based parser editor is intentionally a later version.
For that version, replace built-in rules with a versioned declarative JSON format containing exact hosts, accepted path patterns, canonical host and resolution policy. Validate imports, show synthetic before/after tests, retain a rollback copy, and constrain network destinations independently of user rules. Do not execute downloaded JavaScript or arbitrary parser code. Add an import/export settings screen before considering automatic updates.
Original links are held in memory, not logged or saved. Link UI state is not persisted; screenshots and recents previews are blocked. Only the preview preference is stored. Clipboard writes happen only when Copy is tapped. Online lookup necessarily discloses the short-link path token and IP address to the original site. Documentation and test fixtures must use placeholders, never actual account handles or share tokens.
Version 0.1.1 share-flow regression: seven on-device checks passed for incoming text, ClipData, reused activity delivery, visible preview sharing, homepage rejection, automatic short-link completion and short-link preview. The tests intercept outgoing choosers and use a synthetic resolver response, so no recipient app opens and no real link is transmitted. Run with adb shell am instrument -w app.linkstripper.test/app.linkstripper.ShareFlowTest after building and installing the Android test APK.
