Wall Planner

# Brick Planner (Wall Planner) Android application (Java) for designing a brick wall with a door and/or window — how many bricks are needed, what is the allowance for reserve and approximate price, plus visualization of the masonry. ## What does the app do? - **Language**: Bulgarian, English, Français, Deutsch, Español — selectable from spinner and is preserved between startups, regardless of the system language of the device. - **Measurement system**: Metric (m/cm/mm) or English (feet/inches) — all previously entered values ​​are automatically recalculated upon change. - **Wall and brick dimensions**: wall width/height, brick dimensions the brick and the width of the joint. - **Masonry model**: row connection (50% offset) or straight masonry. - **Opens**: optional door (width, height, distance from left edge) and optional window (width, height, distance from the left edge, height of the sill from the floor) — are subtracted from the masonry area. - **Reserve and price**: technological reserve in percentages, optionally price of brick and number of bricks in a pallet/package. - **Visualization**: `WallView` (custom View) draws a wall elevation with the selected masonry model and depicts the door/window. - **History**: calculations are stored in a local SQLite database (`DatabaseHelper`) and are viewed/deleted from a separate screen. ## Calculation formula in brief 1. Wall area = width × height. 2. Opening area = (width × height of door, if any) + (width × window height, if any). 3. Net masonry area = wall area − opening area. 4. Face of one brick (with joint) = (width of brick + joint) × (height of brick + joint). 5. Bricks needed (net) = rounded up (net area / brick face). 6. Total reserve = user-entered reserve + 5% additional surcharge, if the wall has a door and/or window (due to cut bricks on the edges). 7. Bricks to order = rounded up (net bricks × (1 + reserve / 100)). 8. Pallets/packages = rounded up (bricks to order / bricks in pallet/package), if specified. 9. Price = bricks per order × brick price, if set. Rows/columns (brick courses) are calculated separately using the grid method (width/height of the wall divided by the brick pitch with the joint) and are for information only — the basic calculation of the number is by area, to remain correct in the presence of holes of arbitrary shape/position.
