Why

After a while, turning TST Go back on dropped the chosen location and jumped to New York. The pin only lived in memory. When Android killed the app in the background, the GPS service restarted itself and broadcast the built-in default (Times Square). Reopening the app did the same. The web app had the same gap and sent Times Square to the browser extension on every reload.

There was also no clear way to stop the fake GPS, and opening the app always started broadcasting.

Searching a home address often found nothing, because OpenStreetMap is missing house numbers for many US homes.

On top of that, Google Play now requires app updates to target Android 16 (API 36). The app targeted 34, so Play would reject an update.

What changed

Android (1.0.10, code 11)

• LastPin: saves the last pin (lat, lng, name) to SharedPreferences, once a spot has actually been picked. The GPS service restores it when Android restarts it, and the app restores it on open.
• Never broadcasts the Times Square default. A fresh install leaves the real GPS alone until a spot is picked, and the service skips injecting until a pin is set.
• Stop GPS, all going through one stop path (StopReceiver / stopFakeGps):
  • red Stop GPS / green Start GPS button on the main screen, replacing the small switch
  • Stop GPS on the ongoing notification
  • long-press icon shortcut Stop GPS
  • TST Go stop button home screen widget
• The header shows the installed version.
• Address search:
  • The Search button also asks the US Census Bureau geocoder (free, no key) for anything that looks like a street address.
  • Unit numbers ("Apt 4B", "#12", "Ste. 200") are stripped before searching.
  • Search-as-you-type uses only Photon, biased toward the current pin, after a 450 ms pause.
  • A pending typing search no longer cancels a Search button lookup, or reopens the list after a suggestion is picked.
• MainActivity is singleTask, and notification/widget "open" taps use the launcher intent. Before, they could open a second copy of the screen, and both copies fed their own spot to the GPS service.
• Screen text updates only when it changes, instead of 20 times a second.

Google Play readiness

• compileSdk/targetSdk 36, Android Gradle Plugin 8.9.1, Gradle 8.11.1.
• Draws edge to edge, with controls padded by the system bar and notch insets.
• .github/workflows/android-release.yml (manual): builds a signed .aab from repo secrets and can upload it to a Play track. The track defaults to internal, and production uploads always land as drafts.

Web

• Saves the last broadcast point, so a reload and the extension stay put.
• Search adds the US Census geocoder for street addresses and strips unit numbers (src/lib/geo/address.ts, with tests).

CI (.github/workflows/android.yml)

• Builds the debug APK and release bundle, and runs the unit tests.
• Writes a live report comparing old and new address search on real addresses.
• Runs .github/scripts/android-smoke.sh on Android 11 and Android 15 emulators, with screenshots.
• Publishes the APK and results to the ci/android-output branch.
• Test APKs are signed with one saved key: the TSTGO_TEST_KEYSTORE_BASE64 secret if set, otherwise a key kept in the Actions cache. Each test build then installs over the last one. A cache entry is dropped after 7 days without a build; set the secret to make the key permanent.

Testing

• Emulator test, commit 9c33780: 0 failed checks on Android 11 and Android 15. After the process is killed and after a force stop, the app reopens at the picked spot. Times Square never reaches the phone's location log. Every stop path works. A search for an address with "Apt 2" lands on the right building, and nothing crashed.
• Live address report: the new search found 14 of 14 addresses. The old search put "4600 Silver Hill Rd, Washington, DC 20233" in central DC, about 11 km off. The new one finds the building.
• APK signature checked: the APK is signed with the saved "TST Go test build" key, and the cache step saved that key.
• Web: unit tests pass and typecheck is clean. The web Census lookup was not run against the live service, because this session can't reach it.
• Not tested on a physical phone yet.
