Project description:
"I need a lightweight Android application that talks directly to a live Google Sheet, keeps my production data clean, and sends an automatic email report every day.

The workflow is fixed around four screens:

• Material Receipt – operators enter a raw-material ID, quantity and basic specs; the moment they tap Save the record must post to the Google Sheet and the app must block any attempt to save that same ID again.
• Bundle Creation – from the receipt list we break one raw-material lot into smaller bundles, each with its own dimensions and weight; again, no duplicate bundle IDs may slip through.
• Despatch – once a bundle ships, staff simply select it and mark it despatched; the status change should sync instantly to the sheet.
• Data Viewing – a simple filter bar lets us type a material or bundle ID (or date range) and return every matching row for quick on-device review.

Core requirements
– Target platform is Android only.
– Sign-in is traditional username / password; no Google SSO, no guest access.
– No push notifications are needed.
– All sheet operations must use the Google Sheets API so we can see edits in real time.
– A scheduler inside the app (or a small cloud function you trigger from the app) must email a daily summary report to one address I will provide.
– The UI can be plain, I just need it responsive and error-proof.

Deliverables
1. Source code (Kotlin or Java) with clear comments.
2. A small README covering build steps, API keys and the cron / WorkManager job that sends the email.
3. One-hour hand-off call or video walk-through so my team can take over.

If you have built Google-Sheets-driven Android tools before, let me know; otherwise show me a plan for handling offline edits and duplicate checks. I’m ready to start as soon as we agree on the approach." (client-provided description)
