| Carmel Ventures 14.01.11
• tawkon & nascent brainstormed possible implications of tawkon
running in the background
• Different behaviors interaction styles were considered
• New platform, new questions:
• How does the app interact with other apps?
• How do notifications look?
• Where are the settings ?
• Widgets ?
• What are the best practices?
• What are the platform guidelines?
Outcome:

accommodate background running, notifications, Android
guidelines best practices
• Special care was given to being ‘good citizen’ on Android, as
well as using native controls UI elements where possible.
Outcome:
• Application full map
• UI use cases map
• Must have reference for developer
