Key Concepts

Overview

The Squad SDK enables seamless integration of social features and voice calling capabilities into mobile applications. This guide covers the fundamental concepts and architecture that form the foundation of the Squad SDK.

Core Components

1. SDK Manager

The SDK Manager is the central component that handles:

  • SDK initialization
  • Configuration management
  • Resource coordination
  • Lifecycle management

    A --> C[WebView Bridge]
    A --> D[Voice Manager]
    A --> E[Event Handler]

2. WebView Integration

The Squad experience is delivered through a WebView component that:

  • Provides the user interface
  • Handles user interactions
  • Manages navigation
  • Coordinates with native features

3. Bridge Architecture

The Bridge system facilitates communication between:

  • Native SDK components
  • WebView content
  • Voice calling features
  • Parent application

    Bridge->>Voice: Handle Call

Key Features

1. Authentication Flow

Squad SDK supports multiple authentication methods:

  • Email-based authentication
  • Token-based authentication
  • Session management
  • Secure credential storage

2. Voice Calling (Squad Line)

Voice calling features include:

  • Real-time communication
  • Custom call titles
  • Emoji reactions
  • Call quality management

3. Social Features

Integrated social capabilities:

  • Freestyles
  • Polls
  • Squad management
  • Friend connections

Architecture Patterns

1. Event-Driven Architecture

    A[Event Source] --> B[Event Bus]
    B --> C[Event Handlers]
    B --> D[Analytics]
    B --> E[State Management]

The SDK uses an event-driven architecture to:

  • Handle user interactions
  • Manage state changes
  • Coordinate components
  • Track analytics

2. State Management

State management encompasses:

  • User session state
  • Call state
  • WebView state
  • Connection state

Integration Lifecycle

1. Initialization Phase

// 1. SDK Initialization
SquadSDK.initialize(config)

// 2. User Authentication
SquadSDK.authenticate(credentials)

// 3. WebView Presentation
SquadSDK.presentWebView()

2. Runtime Phase

During runtime, the SDK manages:

  • State synchronization
  • Event handling
  • Resource management
  • Error recovery

3. Cleanup Phase

Proper cleanup includes:

  • Resource release
  • State persistence
  • Connection termination
  • Cache management

Data Flow

1. Client-Server Communication

    Server-->>SDK: Response
    SDK-->>Client: Processed Data

2. WebView-Native Bridge

The bridge facilitates:

  • Bi-directional communication
  • Event synchronization
  • State management
  • Resource sharing

Security Model

1. Authentication Security

  • Secure credential storage
  • Token management
  • Session handling
  • Access control

2. Data Security

  • End-to-end encryption
  • Certificate pinning
  • Secure storage
  • Data privacy

Best Practices

1. Implementation Guidelines

  • Initialize SDK early in app lifecycle
  • Handle lifecycle events properly
  • Implement proper error handling
  • Manage resources efficiently

2. Performance Optimization

  • Optimize memory usage
  • Manage network efficiently
  • Handle background states
  • Cache appropriately

Advanced Concepts

1. Custom Integration

Customization options include:

  • UI/UX customization
  • Custom event handling
  • Analytics integration
  • Error handling

2. Advanced Features

Advanced capabilities:

  • Background processing
  • Push notifications
  • Deep linking
  • State restoration

Platform Considerations

iOS-Specific Concepts

  • View controller hierarchy
