Android App for Local Service Booking with Plumber, Electrician and Cleaner on Demand

Android App for Local Service Booking with Plumber, Electrician and Cleaner on Demand is an Android application that lets a household book a tradesperson — a plumber, an electrician or a cleaner — from a phone, with the price shown before booking. A user picks a trade, chooses one of nine fixed-price job cards such as tap leak repair at ₹349, sees an itemised quote that adds a visit fee to the job price, picks a time slot, and follows the provider through five steps with an ETA. The problem it addresses is the usual way of hiring tradespeople: phone numbers passed by word of mouth, prices negotiated at the door, and no record of who is coming or when. That wastes time, invites inflated charges, and leaves no accountability when the work is poor. This project replaces it with fixed job prices, a quote before booking, and provider ratings — real booking logic, not a static catalogue.

The booking travels a short, visible chain from the user's tap to the provider's arrival. The user picks a trade and a job card; the app reads the fixed job price and the trade's visit fee from the local Room database and adds them into an itemised quote, so the total is known before booking. Choosing a slot creates the booking, saved locally and sent to the server; WorkManager schedules the reminder at the same moment, so it survives the app being closed or the phone restarting. The server offers the job to the nearest available provider; when one accepts, the app switches to the five-step tracking view — confirmed, assigned, on the way, arrived, done — with an ETA from the provider's distance and live status. The provider checks in at the door with an OTP, the job is completed against the quoted price, and the user rates the work, updating the provider's record for the next customer.

1. The user sets a location and browses the trade catalogue, which loads from the Room database and works offline for browsing.
2. The user picks a trade — plumber, electrician or cleaner — and a fixed-price job card such as tap leak repair at ₹349.
3. The app builds the itemised quote: visit fee (₹249 for plumber/electrician, ₹199 for cleaner) plus the job price; parts are shown as an estimate before work starts.
4. The user picks a time slot; the booking is saved in Room and sent to the server, and WorkManager schedules the reminder.
5. The nearest available provider in that trade accepts; the app shows the five-step tracking view with an ETA from the provider's distance and live status.
6. The provider checks in at the door with an OTP, completes the job against the quoted price, and the user rates the work.

Four capabilities carry this project. First, the quote comes before the booking: every job card carries a fixed price, the app adds the trade's visit fee — ₹249 for a plumber or electrician, ₹199 for a cleaner — and the total is shown before the user confirms anything, so the price can never change at the door. Second, emergency dispatch: a booking flagged as an emergency is assigned to a provider within 60 minutes as a design target, covering leaks, short circuits and blocked drains that cannot wait for a slot. Third, slot booking with reminders: the user picks a time slot and WorkManager schedules a reminder that still fires if the app is closed or the phone restarts. Fourth, live provider tracking with a five-step timeline and ETA, so the user always knows who is coming and when. Builder note: booking the tap-leak job end to end gives ₹249 + ₹349 = ₹598, with no hidden line items.

• [Trade-wise service catalogue] Three trades — plumber, electrician, cleaner — with nine fixed-price job cards, each showing its price and typical duration, stored in Room so the catalogue can be browsed offline.
• [Quote before you book] The app adds the trade's visit fee to the fixed job price and shows the itemised total before confirmation; the tap-leak example totals ₹598 (₹249 visit fee + ₹349 job price), checked in the demo build.
• [Emergency 60-minute dispatch] A booking flagged as an emergency is assigned to the nearest available provider within 60 minutes as a design target, for leaks, short circuits and blocked drains.
• [Slot booking with reminders] The user picks a time slot and WorkManager schedules a reminder that persists across app restarts and device reboots, confirmed against developer.android.com.
• [Live provider tracking] A five-step timeline — confirmed, assigned, on the way, arrived, done — with an ETA from the provider's distance and live status; the demo shows arrival in approximately 38 minutes for a provider 2.1 km away.
• [Provider profiles with ratings] Each provider shows a rating and completed-job count, so the user chooses on record rather than on a name alone; the demo's names, ratings and counts are sample data.
• [Offline booking drafts] Bookings and drafts are saved in the Room database on the phone, so a half-finished booking survives the app being closed and syncs when the connection returns.
