Resources: Intro to Developing Apps (RIM)

See today’s lesson:Introduction to Developing Mobile applications

Book 1 - Intro to Mobile Application Development - Module 01 Intro to Developing Applications


Developing for Mobile DevicesDeveloping for Mobile DevicesExercise 1

to be done in groups, with discussion following:1. Identify and describe the differences between mobile applications and typical desktop applications. 2. Identify and describe a user's needs and expectations of mobile applications.


Developing for Mobile DevicesDeveloping for Mobile DevicesExercise 1.1:

Mobile devices are MOBILE! Desktops are not!Mobile devices have smaller storage capacity than desktops.Mobile devices have lower memory capacity than desktops.Limited power on mobile devices; desktops can run continuously without worrying about power and can run power-intensive apps.Smaller and varying screen size on mobile apps.Mobile apps – different input methods; desktops = touch-typing.Desktops can display multiple app screens at the same time; mobile apps display only a single app screen at a time.Mobile devices use wireless, so slower data transfer rates and less reliable.



Users want time-sensitive information quickly (60 second rule).Users want only the most relevant information – only the options/info most relevant to the current task. Simple and easy-to-use, consistent.

Developing for Mobile DevicesDeveloping for Mobile DevicesExercise 2

to be done in groups, with discussion following:1. Define the three types of mobile applications. 2. Describe the advantages and disadvantages of each method of mobile application development.



Java ApplicationsJava MEReside and run on mobile deviceDoesn’t need to access internet after download/installationCan synchronize with apps/data on computer

Web ApplicationsApp resides on content server and is accessed on device with the web browserHTML/XHTML, images, JavaScript, CSS, Ajax, etc.Example: cbc.ca/mobile


Developing for Mobile DevicesDeveloping for Mobile DevicesExercise 2.1, continued:

WidgetsSingle-purpose apps developed with web technologiesRun as an application in its own instance of a web browser so it looks like a regular appCan be stand-alone app or can be connected to Internet.Example: foodnetwork.ca app



Java Apps, Advantages:Flexibility re style, function, appearanceCan take advantage of existing device features (maps, media player, contacts)Can communicate with peripheral devices via Bluetooth easily (standardized)Anytime access – app resides on deviceAccess to location-based services.Can use background threads/processes.Some require no bandwidth, or can develop a “push” app to minimize bandwidth



Java Apps, Disadvantages:Skill requirements – need to know how to program!No existing framework so you need to figure out how to present your app’s featuresLimited local storage.You need to develop different application versions for a variety of different devices.



Web Apps, Advantages:No issues with storage capacity since everything is stored on content server.

Can work with existing frameworks

e.g. use same connection, compression, encryption as BB email app and don’t have to build these

Access to web signals

http://na.blackberry.com/eng/services/websignals/

Version control – just update the one version on the content server

Can detect device type and capabilities



Exercise 2.2, continued:Web Apps, Disadvantages:

Existing framework can limit creativity.No true background processes – can run web app concurrently with other apps.Must have Internet connection to content server.Uses bandwidth so must avoid large uploads/downloads.



Exercise 2.2, continued:Widgets, Advantages:

Can apply application-like features without knowing programming language

Can use existing web technologies

Features and content specific to user needs, customizable.Can use device features e.g. location based servicesUse less bandwidth – send/rec’v smaller amounts of dataCan use existing content already created from web app or from content server



Exercise 2.2, continued:Widgets, Disadvantages:

Similar to disadvantages of web apps:Less flexibilityReliance on Internet connectionNot suitable for larger, more complex tasks
