1. Project Scenario Assessment

Before starting development, assess the current project state:

Scenario	Characteristics	Approach
Empty Directory	No files present	Full initialization required, including Gradle Wrapper
Has Gradle Wrapper	gradlew and gradle/wrapper/ exist	Use ./gradlew directly for builds
Android Studio Project	Complete project structure, may lack wrapper	Check wrapper, run gradle wrapper if needed
Incomplete Project	Partial files present	Check missing files, complete configuration

Key Principles:

• Before writing business logic, ensure ./gradlew assembleDebug succeeds
• If gradle.properties is missing, create it first and configure AndroidX

1.1 Required Files Checklist

2. Project Configuration

2.1 gradle.properties

# Required configuration
android.useAndroidX=true
android.enableJetifier=true

# Build optimization
org.gradle.parallel=true
kotlin.code.style=official

# JVM memory settings (adjust based on project size)
# Small projects: 2048m, Medium: 4096m, Large: 8192m+
# org.gradle.jvmargs=-Xmx4096m -Dfile.encoding=UTF-8

Note: If you encounter OutOfMemoryError during build, increase -Xmx value. Large projects with many dependencies may require 8GB or more.

2.2 Dependency Declaration Standards

dependencies {
    // Use BOM to manage Compose versions
    implementation(platform("androidx.compose:compose-bom:2024.02.00"))
    implementation("androidx.compose.ui:ui")
    implementation("androidx.compose.material3:material3")
    
    // Activity & ViewModel
    implementation("androidx.activity:activity-compose:1.8.2")
    implementation("androidx.lifecycle:lifecycle-viewmodel-compose:2.7.0")
}
