Genwise

A single-screen Kotlin Android app that takes a name and an age and labels the person as Child, Teenager, Adult, or Senior.

Status

Educational/portfolio sample. One activity, one layout, one bucketing rule. No persistence, networking, or external services.

Features

• Single form with a name field and a numeric age field.
• Tap Submit, or press the keyboard Done action on the age field, to evaluate the input.
• Validates that the name is non-empty and the age parses to a non-negative integer; otherwise shows a toast.
• Reveals two result lines: a "Hello, {name}!" greeting and a category label.
• Categorizes age into Child (<13), Teenager (13–19), Adult (20–59), or Senior (60+).
• Result texts start hidden and become visible after a successful submission.
• Clears focus on both inputs after evaluating.

Tech Stack

• Language: Kotlin (JVM target 11).
• UI: Android Views with AppCompat, Material Components, and ConstraintLayout.
• Build: Android Gradle Plugin via libs.versions.toml; compileSdk 35, minSdk 24, targetSdk 35.
• View Binding enabled (buildFeatures.viewBinding = true).

The application id and namespace are com.example.agegroupapp; the displayed app label uses the app_name resource and the Theme.AgeGroupApp style.

Getting Started

Prerequisites

• Android Studio compatible with the wrapper version in gradle/wrapper.
• JDK 11.
• Android SDK with compileSdk 35 and minSdk 24.

Run

git clone https://github.com/shayann07/Genwise.git

Open the project in Android Studio, let Gradle sync, then run the app configuration on a device or emulator.

Build

./gradlew :app:assembleDebug

The repository tracks a local.properties; replace its sdk.dir value with the path on your machine before building.

Limitations

• Despite the project name, the app does not classify users into generational cohorts (Gen Z, Millennial, Boomer, etc.). It buckets a raw age number into four broad categories.
• Result strings are hardcoded English; there are no translations or accessibility-focused result components beyond the standard Material widgets.
• No data is persisted between launches.
• The application id and namespace are still the starter project's com.example.agegroupapp.
• Only generated example tests are present and there is no license file.
