- 4. MTJ Overview Extend existing Eclipse platform to support mobile Java application development Integrates with most Software Development Kits (SDKs) available MTJ does not ship any SDK, it is the device manufacturer's responsibility to distribute their SDKs Vendor A UEI SDK MTJ JavaME SDK Extens. JDT Vendor Vendor B Eclipse Platform Proprietary JavaME SDK Protocol 4

- 9. Application Packaging Resolves project dependencies Packages third party libraries 9

- 11. Package Obfuscation MTJ integrates with proguard to provide obfuscation ProGuard is an open source Java class file optimizer, obfuscator Proguard must be downloaded separately from MTJ Proguard WebSite (http://proguard.sourceforge.net/) 11
- 12. Demo Part 1 Import installed SDKs Create a MIDlet Suite Project Create a MIDlet from a template Part 1 Package application for deployment Create an obfuscated package for deployment Run/Debug Application 12

- 14. Multi device configuration Applications are developed for a wide range of devices Device fragmentation problem affects mobile developers MTJ allows developing applications for multiple target devices 14
- 15. Multi device configuration Every configuration has one associated device Every configuration has it's own symbol set Workspace level symbol sets (imported from device database) 15
- 16. Multi device configuration It is possible to package either one or all configurations Every configuation is packaged on it's own folder under the deployed folder 16
- 17.
- 18. Build Configuration Every device configuration requires a different set of resources Customizing packages for different devices manually is very error prone The build editor allows selecting which resources to package on each device configuration 18

- 20. Preprocessing Preprocessing is very usefull since mobile applications need to target several devices MTJ uses Antenna in order to provide preprocessing support Antenna is another open source project. It can be dowloaded from (http://antenna.sourceforge.net/) Antenna preprocessor defines Preprocessor language //#if ScreenWidth>100 && ScreenHeight>120 do something; //#else do something else; //#endif 20
- 21. Preprocessing Built in code assitant for preprocessing statements All available statements are listed with brief descriptions 21
- 22. Preprocessing Built in code assitant for preprocessing symbols ● It is possible to define custom symbols ● Each symbol has Name, Value, if active on active configuration 22
- 23. Demo Part 2 Setup multi device configuration Setup build configuration Enable preprocessing Part 2 Manage preprocessing symbol sets Add preprocessing to our example Build and package applications for all configurations 23
- 24. Internationalization Preprocessing Build Configuration Multi Device Support Package Obfuscation Application Packaging MIDlet Templates Mobile Tools for Java Overview 24
- 25. Localization Mobile applications are used all over the world Localizing applications must not bring an overhead to the development process 25
- 26. Localization Localization is done through key/value pairs Keys will have localized values for every locale desired All keys defined are available to the application's code 26
- 27. Localization A properties file is generated for every locale configured The L10nResources class is used to get the localized values All localized keys are created within the L10nConstants class 27

- 29. Unit Testing Every application needs to be tested in order to achieve quality standards The testing framework must be tightly integrated within the IDE 29
- 30. Unit Testing Running/Debugging test cases is as simple as running a MIDlet The test results are exibited on the device's screen It is possible to package the tests in order to run on a real device 30
- 31. Demo Part 3 ● Setup localization ● Create localized resources ● Add localization into the application code Part 3 ● Enable unit testing ● Create Unit Tests/ Suites ● Run Tests 31
