Android UI Kit Call Features Documentation Review - Complete

​
Summary

Reviewed and improved the ui-kit/android/call-features.mdx documentation to ensure a natural integration flow with clear next steps and comprehensive guidance. Critical correction made: Simplified the incoming call implementation to show the CometChatIncomingCall component directly, keeping the code minimal and flexible for different UI implementations.

​
Critical Issues Found & Fixed

​
1. Simplified Incoming Call Implementation (CRITICAL)

Problem:
  • Documentation showed using CometChatCallActivity.launchIncomingCallScreen() which doesn’t exist
  • This would cause runtime errors for developers following the documentation
  • Overly complex implementation with unnecessary boilerplate
Fix:
  • Simplified to show direct usage of CometChatIncomingCall component
  • Kept implementation minimal and flexible
  • Added note explaining different display options (Activity, Dialog, Snackbar, etc.)
  • Developers can choose how to display the component based on their app’s architecture
  • Removed unnecessary Activity creation steps
Code Approach: 
// Simple, direct component usage
val incomingCallView = CometChatIncomingCall(context)
incomingCallView.call = call
incomingCallView.disableSoundForCalls(false)
incomingCallView.fitsSystemWindows = true
incomingCallView.onError = OnError { exception -> /* handle */ }
// Display as needed (Activity, Dialog, Snackbar, etc.)

​
2. Integration Section Issues

Problems:
  • Code block had incorrect language tag (javascript instead of gradle)
  • Missing clear step-by-step structure
  • Typo: “sudgest” → “suggest”
  • Grammar: “To start receive calls” → “To receive calls”
  • Unclear explanation of when/why to add CallListener
Fixes:
  • Changed code block language from javascript to gradle
  • Restructured into clear Step 1, Step 2, Step 3 format
  • Added descriptive headers for each integration step
  • Fixed all grammar and spelling errors
  • Added explanation of why CallListener is needed
  • Added “What Happens Next?” section to clarify the outcome

​
3. Code Examples Issues

Problems:
  • Inconsistent code formatting
  • Missing context in comments
  • No explanation of AndroidManifest.xml requirement
Fixes:
  • Improved code comments for clarity
  • Added consistent formatting across Java and Kotlin examples
  • Added <Note> component with AndroidManifest.xml registration instructions
  • Improved variable naming (made LISTENER_ID final/const)
  • Simplified code to show minimal implementation

​
4. Features Section Issues

Problems:
  • Minimal descriptions of each component
  • No clear use cases provided
  • Missing key features lists
  • No guidance on when to use each component
  • Abrupt transition between sections
Fixes:
  • Renamed “Features” to “Call Components” for clarity
  • Added comprehensive descriptions for each component
  • Added “Key Features” bullet lists for each component
  • Added “Use Cases” sections showing practical applications
  • Added clear navigation links to detailed documentation
  • Added reference to Call Log Details guide
  • Improved section flow and transitions

​
5. Missing Content

Problems:
  • No troubleshooting section
  • No permissions documentation
  • No next steps guidance
  • No additional resources section
Fixes:
  • Added comprehensive “Troubleshooting” section with common issues:
    • Call Buttons Not Appearing
    • Incoming Calls Not Showing
    • Call Quality Issues
    • Build Errors After Adding Calls SDK
  • Added “Permissions Required” section with complete AndroidManifest.xml example
    • Includes all required permissions for CometChat calling features
    • Organized into Core Permissions and VoIP Permissions
    • Added detailed explanations for each permission
    • Includes media permissions for Android 13+ (READ_MEDIA_IMAGES, READ_MEDIA_VIDEO)
    • Includes notification permissions for Android 13+ (POST_NOTIFICATIONS)
    • Includes VoIP-specific permissions (MANAGE_OWN_CALLS, WAKE_LOCK, ANSWER_PHONE_CALLS, etc.)
  • Added runtime permissions note for Android 6.0+
  • Added “Next Steps” section with clear action items
  • Added “Additional Resources” section with links to related documentation

​
Content Improvements

​
Structure Enhancement

  • Clear hierarchical organization (Overview → Integration → Components → Next Steps → Troubleshooting)
  • Logical flow from setup to implementation to troubleshooting
  • Better use of Mintlify components (Frame, Note, Tabs)

​
User Experience

  • Step-by-step integration guide
  • Clear explanations of what happens at each step
  • Practical use cases for each component
  • Troubleshooting guidance for common issues
  • Complete permissions documentation
  • Minimal, flexible code examples

​
Technical Accuracy

  • Correct code block language tags
  • Accurate code examples showing direct component usage
  • Proper component references
  • Complete permission requirements
  • Flexible implementation approach

​
Recommendations for Future Enhancements

  1. Add Video Tutorial - Consider adding a video walkthrough of the integration process
  2. Add Sample App Link - Link to a complete sample app demonstrating all call features
  3. Add Migration Guide - If there’s a v4 to v5 migration, add specific call features migration notes
  4. Add Performance Tips - Add section on optimizing call quality and performance
  5. Add Testing Guide - Add guidance on testing call features in development
  6. Add UI Examples - Show different ways to display the incoming call component (Dialog, Snackbar, Full-screen)

​
Conclusion

The call-features documentation is now complete, accurate, and user-friendly. The integration flow is natural, next steps are clear, and developers have all the information they need to successfully implement calling features in their Android apps. The simplified approach gives developers flexibility to integrate the component in a way that best fits their app’s architecture.
