Xposed 模块开发实战：从零构建功能完整的系统增强模块

本文将通过开发一个完整的 Xposed 模块来展示实际开发流程，该模块将实现系统增强、应用管理和隐私保护等多种功能。

项目需求分析

模块功能规划

我们将开发一个名为 "SystemEnhancer" 的 Xposed 模块，包含以下功能：

// ModuleFeatures.java - 功能规划
package com.example.systemenhancer;

public class ModuleFeatures {
    
    // 1. 系统增强功能
    public static final String FEATURE_SYSTEM_ENHANCEMENT = "system_enhancement";
    public static final String FEATURE_STATUS_BAR_ENHANCEMENT = "status_bar_enhancement";
    public static final String FEATURE_NAVIGATION_BAR_ENHANCEMENT = "navigation_bar_enhancement";
    
    // 2. 应用管理功能
    public static final String FEATURE_APP_MANAGEMENT = "app_management";
    public static final String FEATURE_APP_LOCK = "app_lock";
    public static final String FEATURE_APP_CLONE = "app_clone";
    
    // 3. 隐私保护功能
    public static final String FEATURE_PRIVACY_PROTECTION = "privacy_protection";
    public static final String FEATURE_PERMISSION_CONTROL = "permission_control";
    public static final String FEATURE_DATA_PROTECTION = "data_protection";
    
    // 4. 性能优化功能
    public static final String FEATURE_PERFORMANCE_OPTIMIZATION = "performance_optimization";
    public static final String FEATURE_MEMORY_OPTIMIZATION = "memory_optimization";
    public static final String FEATURE_BATTERY_OPTIMIZATION = "battery_optimization";
    
    // 功能开关配置
    public static class FeatureConfig {
        public boolean systemEnhancementEnabled = true;
        public boolean appManagementEnabled = true;
        public boolean privacyProtectionEnabled = true;
        public boolean performanceOptimizationEnabled = false;
        
        // 详细配置
        public boolean statusBarClockCustomization = true;
        public boolean navigationBarHide = false;
        public boolean appLockEnabled = true;
        public boolean permissionSpoofing = false;
        public boolean memoryCleanup = false;
    }
}
