I need a lightweight Android application written entirely in B4A that connects to an existing MS SQL database. Once the connection string is set, the flow should be straightforward: • User authentication is handled by a simple username-and-password form that validates against a table I will provide. • After a successful login, the user lands on a screen that pulls all available tests into a single dropdown list; on change, the selected value should trigger an SQL call for that test ID. • The returned data include both a textual summary and the numeric fields required to draw one or two quick charts. Display the summary first, then embed the charts below it so the layout remains clean on phones. • Each test record also stores a file path (or URL) for an image; fetch and render that image at the bottom of the same screen. I will supply table names, field names, and a sample connection string. Please keep the code modular—separate subs for SQL queries, chart rendering, and image loading—so I can slot it into a larger project later. Final hand-over must include the complete B4A project folder plus an installable APK for quick testing.
