Device fragmentation Different characteristics of devices must be taken into account Physical device characteristics, e.g. display resolution,-size and buttons, processing power and memory Quirks in the OS, API and Java virtual machine implementations Variation comes also from APIs supported by each device Flavours of Symbian (S60, S80, S90) and other mobile OS versions J2ME profiles and configurations CLDC 1.0/1.1 and MIDP 1.0/2.0 Optional APIs for Bluetooth, 3D, Multimedia, Web Services, etc. Proprietary APIs from device manufacturers and operators In addition, there are other operator and market requirements Localisation, branding, billing, etc. New devices and APIs are introduced frequently Huge amount of configurations Varying devices Varying devices Differing assets Differing assets Operator requirements Operator requirements

Device fragmentation, Mobile value chain Application Developers Content aggregators and Distributor Network operators End-user / consumer Infrastructure providers Device manufactures RetailRetail This diagram represents the major players in the wireless industry. Application- and Content providers have partnered with Network operators to design and develop Java solutions for consumers. Content aggregators license content from its creators and format it to be used with specific devices and networks. Content distributors create the revenue by providing the distribution channels. Network operators (carriers) and Infrastructure providers control the wireless network and own the customer information. Device manufactures drive the technical innovation through the new hardware. The application developers and content aggregators needs most tools against the device fragmentation. Legend Information exchange Cash flow exchange

Device fragmentation, pre-processing Definition: Pre-processing changes the source code before it is compiled. It allows conditional compilation and inclusion of one source file into another and is helpful when trying to maintain a single source for several devices, each having its own bugs, add-on APIs, etc. and it enables device optimization. The Eclipse JDT could add support for pre-processing, alternative could be e.g. J2ME Polish, which can be integrated to Eclipse (licensing must be checked) or re-implementing the similar functionality.J2ME Polish One key feature is the device description database, that helps to create tasks or actions against similar devices. The device description database enables that developers can identify and group devices with an keyword, that can be used e.g. in pre-processing.

Build management The build environment is heavily relying on Eclipse, but there are plans to support also Ant. One planned extension to Ant is the Antenna –project, which provides a set of Ant tasks suitable for developing wireless Java applications targeted at the J2ME and Mobile Information Device Profile (MIDP).AntAntennaMobile Information Device Profile The build management enables that the build process can be configured to suit for the active project needs. E.g. what build providers are used as default and how the building process works. The target device management provides data about selectable devices and J2ME platforms (SDK Emulators) and enables that the Runtime Platform Definition. The selected default target Device Platform is then activated to the projects use.

Deployment and Runtime management The MTJ provides an Deployment and DevicePlatform frameworks that supports the existing SDK Emulators and phones runtimes The framework publishes a Device Platform -interface, that capsulate (hides) the actual runtime environments and protocols. The framework separates the different vendors products to own plug-ins EclipseEclipse SDK / Emulator (Vendor X) Vendor X SDK Emulator Plug-in Vendor X SDK Emulator Plug-in MTJPlug-inMTJPlug-in Device Platform Device Platform Extension point SDK / Emulator (Vendor Y) Vendor Y SDK Emulator Plug-in Vendor Y SDK Emulator Plug-in SDK / Emulator (Vendor Z) Vendor Z SDK Emulator Plug-in Vendor Z SDK Emulator Plug-in Vendor X Real Device Plug-in Vendor X Real Device Plug-in Real Device Real Device (Vendor X) Vendor Y Real Device Plug-in Vendor Y Real Device Plug-in Real Device Real Device (Vendor Y)

Device Management The device management in this scope focuses to enable detecting, visually showing, identifying and visually managing the available mobile devices. There should be ability to group devices with similar configuration based on some criteria. This grouping could be used e.g. in the packaging / building / localization / deployment / branding processes.

Signing and Obfuscation Signing MIDP 2.0 (JSR-118) includes enhanced mobile code and application security through a well-defined security manager and provisioning process. During the provisioning the MIDP applications are signed with an certificate, which ensures their security and makes them trustworthy.JSR-118 Trusted MIDlet suites can be granted access to API's without explicit user authorization, and have wider access to device API's. Obfuscation By using an Obfuscator tool, the source code can be made more difficult to reverse-engineer and also there can be some code optimization benefits achieved at the same time. Obfuscation can be done e.g. through an ANT task that activates an Obfuscator tool and it performs the obfuscation against the parameterized source code location.

Localization Localization (I18N/L18N) is a major issue in the wireless space, where a single app deployed to a single carrier may need to support many languages and character sets. Key requirements: The Localization architecture should be capable of supporting all languages. It should remove the need for application developers to decide which encoding the application will support. The Localization architecture should be aware the UI differences in devices so that the developers wont have to (e.g. the width and length of a device screen). The localization should enable that the service providers can extend the language supports during the deployment phase. Allow local users to select their preferred languages as provided by the application. There should be visible UI simulation that enable to verify the UI immediately when the users switch the locale. The localization should support at leas two approaches: By creating a resource file (.properties) and adding there the selected source files localizable keys. By enabling such optimization to bind the localization directly to the application.

Application Flow The Application Flow creates kind a action diagram, where the visible and invisible actions are drawn on a graphical editor. The AF-editor enables that developer can design e.g. mobile application UI flow.

GUI Editor The Eclipse Visual Editor provides an extensible GUI framework, that can be used in the mobile IDE UI area. Why VE: The VEs framework provides a lot of extension points to different kind of GUI editors Benefits: The GUI editors would have common base framework and the there is a need to implement only the delta of the different mobile GUI editors Now existing: The base GUI framework. What is needed: The mobile screen engines with UI widgets to LCDUI area. VE doesnt provide any multimedia services yet.

Device Runtime Platform Definition 1..n 1 1 Device Profile DP Service API API Device Configuration DC Runtime Platform JVM Impl. 1 Device instance defines the Runtime Platform Definitions that its capable to run on. Runtime Platform consists of Device Configuration, Device Profile, Service APIs and JVM Implementation. Device Configuration defines used configuration (i.e. CDC or CLDC) and its version. Device Profile defines used profile (i.e. MIDP) and its version. Service APIs are either APIs that are defined in Device Profile or API of optional Services that the Devices OS is supporting. Runtime Platform Definition is always based on defined Mobile SDK JVM Implementation.

Service API API Runtime Platform (cont.) JVM Impl Service API –object contains the standardize service name and its version, i.e. WMA 1.1, MMAPI 1.1 or Location API 1.0. Service API has also reference to JAR Library that implements the API.

Device Management architecture Each Mobile project may select the targeted devices, that the project is supporting. Mobile Project contains one or more Device Platforms, thus there is only one default mobile SDK active. The Device Platform and Device instances definition is stored inside the EMF based Device model and the with extendable persistence component the definition is shared with in several projects. The Runtime Platform Definition data is also stored and shared among projects and the Fragmentation Definition can enhance the task to find compatible device groups. Also the pre-processing can use this to provide and define the device grouping inside the JDT.

Deployment framework architecture The MTJ provides an Deployment framework that supports the existing SDK Emulators and phones runtimes. The framework publishes an deployment interface, that capsulate (hides) the actual runtime environments and protocols. The framework separates the different deployment low-level services to own components (like UEI, OTA, etc.) with supporting existing proprietary emulator and phone access (marked as X and Z). It also provides a new development branch to the OBEX based deployment, which can be used e.g. towards to MAC OS environment. Thus this requires that the needed protocols / protocol wrappers are available.

Mobile vendor specific view details Different mobile vendors can use their existing emulators and add the deployment (emulator) specific plug-in to the MTJ environment. The emulator specific plug-in may be even in binary format, if it needs to protect some internal implementation or specification. The emulator specific plug-in uses the MTJ generic API and also contributes to the MTJs deployment frameworks extension point. The deployment framework could provide an template from such plug-in that helps to other vendors to tie up their specific solutions. The deployment framework supports also that the emulator is discovered by manual entering the location. There could be a dynamic plug-in, that ties the discovered emulator to the deployment framework. The deployment framework can provide also other extension points, that enables others to extend e.g. the emulator specific properties, UIs etc. The deployment framework provides a plug-in template for existing emulators, which can dynamically be attached to wrap the specific emulator.

Deployment framework design Integrating to the existing SDK Emulators: Deployment framework Enables adding a new SDK Emulator by manually entering the location or by local hard drive browsing (typical case for existing emulators). Hides the used targeted runtime environments behind a few deployment interfaces Simplifies the deployment process against the device / emulator variation Generalizes the deployment management by encapsulating the SDK Emulator dependencies to a separate plug-ins, thus enabling it to publish its own specific functionality. Integrating to new SDK Emulators, which do have a specific plug-in: Deployment framework If the SDK Emulator has own deployment plug-in and the plug-in does follow the Deployment framework extension rules, its automatically instantiated Deployment framework instantiates Deployment component and calls its methods via deployment interface Deployment component plug-in Implements the Deployment frameworks interface Contributes to the Deployment frameworks extension point May also extend some SDK Emulator specific services to the Deployment framework

58 Signing and Obfuscation Signing and Obfuscating internal architecture

Signing architecture There is a SecurityManager, that manages the keys and certificates in the IDE environment globally. Each project can configure the signing options and parameters against the actual needs. The Signing Provider implements the actual signing and it can be used through e.g. the Ant scripts.

Obfuscating architecture It is a well known fact that Java Class (bytecode) files can be easily reverse-engineered because Java compiler leaves a lot of such information into bytecode that helps the reverse-engineering task. Code obfuscation is one protection tool for Java code to prevent reverse engineering. Code obfuscation makes programs more difficult to understand, so that it is more resistant to reverse engineering. Obfuscation techniques fall into three groups: Layout Obfuscations Layout Obfuscations modify the layout structure of the program by two basic methods: renaming identifiers and removing debugging information. Almost all Java obfuscators contain this technique. Control Obfuscations Control Obfuscations change the control flow of the program. Data Obfuscations Data Obfuscations break the data structures used in the program and encrypt literal. The MTJ enables to use existing Obfuscator -products through an wrapper plug-in (Obfuscation Provider), that can be further tailored.
