Title: Streamlining Flash Express Courier Dev: Handling v1.4.8 Builds on the Static Open HTTP Server Slug: flashexpress-courier-release-v1.4.8-dev-tmp Tags: FlashExpress Android DevOps APK StaticServer

The Scenario If you are part of the development or QA team for the Flash Express Courier app, you know the drill: rapid iterations, frequent staging builds, and the need for a reliable, no-fuss distribution method to internal testers. Recently, while working on the release candidate pipeline, we pushed the latest build: flashexpress-courier-release-v1.4.8.apk . Instead of clogging up Git LFS or using a heavy artifact repository for every temporary build, we opted for a lightweight solution: http- static-open.flashexpress.com . Here’s how we used the development tmp (temporary development) space to host this build and why this pattern works. Why a Static Open HTTP Server? For internal development, you don’t always need a full CDN or a Play Console internal track. Sometimes you need:

Instant uploads (no CI pipeline wait times). Easy access for 3-5 testers via a raw link. No authentication friction for a short-lived build (hence "open"). A clean, predictable URL structure.

Our http- static-open.flashexpress.com subdomain serves exactly that purpose. It’s our shared, low-ceremony space for temporary (tmp) development artifacts. The File in Question: flashexpress-courier-release-v1.4.8.apk This APK represents the v1.4.8 release candidate for the courier-facing app. Key changes in this build include: Title: Streamlining Flash Express Courier Dev: Handling v1

Optimized route polling intervals (reduces battery drain by ~12%). Fix for barcode scanning on Android 13+ devices. New proof-of-delivery photo compression logic.

How We Deployed It (The 30-Second Method) # 1. Build the release APK (already done via Gradle) ./gradlew assembleRelease 2. Copy to the local static server directory cp app/build/outputs/apk/release/flashexpress-courier-release-v1.4.8.apk /var/www/static-open.flashexpress.com/development/tmp/ 3. (Optional) Generate a checksum for verification sha256sum flashexpress-courier-release-v1.4.8.apk > flashexpress-courier-release-v1.4.8.apk.sha256 4. Confirm the file is reachable curl -I http://static-open.flashexpress.com/development/tmp/flashexpress-courier-release-v1.4.8.apk

After that, the direct download link is: http://static-open.flashexpress.com/development/tmp/flashexpress-courier-release-v1.4.8.apk Important: This is a Temporary Space Notice the /development/tmp/ path. That is intentional. We enforce a 72-hour retention policy on anything under /tmp/ . After that, a cron job purges old files. This prevents stale APKs from being accidentally distributed to production couriers. Do not use this space for final releases. Use the official CDN or app store channels for production. Security & Access Note Because the server is static-open , there is no basic auth . This is acceptable for: Here’s how we used the development tmp (temporary

Internal dev builds Staging tests behind a corporate VPN (we whitelist office IPs at the firewall level)

It is not acceptable for customer-facing or sensitive pre-release builds. If you need privacy, move to a private S3 bucket or a secured artifact manager. Final Thoughts For a quick iteration cycle on v1.4.8 , the combination of a simple HTTP static server + a clear development/tmp namespace is hard to beat. It saved us 15 minutes of Jenkins queue time and let the QA lead grab the APK instantly on their device. Next step: Once v1.4.8 passes smoke tests, we’ll promote it from tmp to the official staging bucket and finally to production.
