The document discusses various aspects of cross-platform mobile application development, including the characteristics, advantages, and challenges associated with native, hybrid, and cross-platform apps. It highlights frameworks like PhoneGap, Apache Cordova, and Titanium, emphasizing the importance of understanding different programming languages and tools for successful mobile app development. The conclusion suggests that webkit serves as the new virtual machine in developing mobile applications, allowing JavaScript to integrate seamlessly with native code.
Cross platform mobile application development
- 2. Topics Understanding Mobile Apps • Cross Platform Mobile App Development • PhoneGap • Native Mobile App Development • Hybrid Mobile App Development
- 5. Characteristics Camera and Voice Recording NFC (Near Field Communication) turning phone into Credit Card, Access Card, Business Card Exchanger
- 7. Characteristics Push Notification Notifying the User proactively
- 8. Challenges in building Mobile Applications
- 9. Challenges – Mobile App Dev Windows 7 Fragmentation with many operating systems
- 10. Types of Mobile App Dev • Native Mobile Apps • Cross Platform Mobile Apps • Hybrid partly Native partly Cross Platform
- 11. Native Mobile Apps When To • Long Running Services • Complex N/W comm. • Canvas based Apps • Only Few Platforms When Not To • Replica Web Apps • Standard Restful • Widget based apps • Many Platforms
- 12. Cross Platform Mobile Apps When To • Complex backend Apps • Standard Restful • Widget based apps • Many Platforms When Not To • Long Running Services • Complex N/W comm. • Canvas based Apps • Only Few Platforms
- 13. Hybrid Mobile Apps When To • Fairly Simple UI • Complex Backend • Quite few platforms Why To • Some parts of app are common • Rest parts are different • Use Cross Platform to develop common part • Use Native to develop the weight lifting parts
- 14. Cross Platform Mobile App Development
- 15. Cross Platform Strategies Common Platform e.g WebKit Mapping to Native PhoneGap Apache Cordova Titanium Cross Platform Source Code
- 16. WebKit Platform • All Mobile Platforms have something common that is a Modern Browser • All these browsers are based on WebKit - Apple and Android • Moreover all these platform support showing embedded browser in Applications ( WebView) • Strange enough all these WebViews provide hooks from javascript to java and vice a versa • In short WebView is the new Virtual Machine
- 17. Mapping to Native Code • Say Application is written in JavaScript • The JavaScript code is running in Interpreter • The Interpreter internally forwards calls to the native code • Limitation being the you can only map to subset of code available on all target platforms. • OR you allow for fragmentation in api, like Titanium Mobile does for involving Android services
- 18. Mobile App Dev Frameworks Common Platform • PhoneGap / Apache Cordova • Titanium Desktop Mapping to Native • Titanium Mobile • Rho Mobile
- 19. Apache Cordova / PhoneGapMobile app development
- 20. PhoneGap / Apache Cordova • Only platform to support 6 Platforms
- 21. PhoneGap Prerequistes • Need to be acquainted with Android, IOS, BlackBerry, WebOS • Need to be expert at HTML/Javascript or framework like GWT • Need to be acquainted with JavaScript libraries like • Ionic ,Angular.js • Prototype • Etc • Or Ajax framework like GWT • Use existing IDEs like Eclipse or Xcode, PhoneGap has no IDE
- 22. Titanium Mobile
- 24. Titanium Prerequistes • Need to be acquainted with Android, IOS programming • Need to know JavaScript • Use Titanium Mobile IDE to configure projects and use Text IDE to edit the code
- 26. Native App Development • Basically you need to hire experts who can • Build Android, IOS, BB, BlackBerry and Windows mobile apps • Devs should have experience to deploy apps on market • Devs should have experience on various devices • QA should know how to automate things on devices/emulator • Have concrete plans on • What is Trial app? • How does user upgrade? • Use in app billing to have fine grained control • Plan for risks if this is your companies first Mobile App deployment
- 28. Hybrid App Development • Have Web Developers for Common UI • Have native code experts for heavy weight lifting • Use frameworks like PhoneGap to glue the above two pieces • Measure at every milestone to keep track of effect of changes • Use Automation to regress every layer
- 29. Comparison Titanium • Gives out native app • API is more proprietary • UI has Limitations • UI will be fast • Much better User Experience • Portal Code can not be reused • Extensions are possible • Limited support for HTML/Javascript PhoneGap • Gives out a mobile web app • API is less proprietary • UI possibilities are unlimited • UI could be slow • User Experience will get better with enhancements • Portal Code can be reused • Plugins are possible and easy to implement More will come out of discussion, comments are welcome
- 30. Conclusion • Webkit is the next Virtual Machine. • Js work anywhere
- 31. Cross Desktop App Dev • Following are options worth considering • Nokia QT (webkit based) • Titanium Desktop (webkit based) • Adobe Air (flash based) but slow • Java • Many more
- 32. JavaScript to Native Channel • Assume a single channel from Javascript to native and back from native to Javascript is present • This Single Channel can provide infinite control to the native code. One needs to just add more code to the native end and add new messages for it to be exposed. • However, understand that Javascript is single threaded and the callbacks will execute only if there is no javascript running.
