• convenience

• personalization

• productivity

these are the three benefits of using mobile apps

convenience

benefit of using mobile apps:

• a mobile app user can access and share information anytime or anywhere and internet connection is not required on most apps

personalization

benefit of using mobile apps:

• a user can change the settings of the mobile app based on his preferences and receive notifs real time

productivity

benefit of using mobile apps:

• users can write, read, and present their reports using only their mobile phones

• manage multimedia files and share to friends through social sites

integrated development environment (IDE)

is a programming environment that has been packaged as an application program

it consists of a code editor, compiler, debgger, and a GUI builder

what does an IDE typically consists of?

• android studio

• xcode

• xamarin

• corona

• apache cordova

these are 5 examples of IDEs used in developing mobile apps

android studio

is the official IDE for android application development

IntelliJ IDEA

android studio is based on a Java IDE, which is?

Xcode

this allows users to build apps and run them directly on their apple devices

swift

in Xcode, the programming language used is ___, created by apple for iOS, OS X, and watchOS development

xamarin

this extends the .NET developer platform with tools and libraries specifically for building cross-platform apps

corona

a free, cross-platform framework ideal for creating mobile apps and games

lua

corona uses an easy-to-learn scripting language, which is?

apache cordova

is an open-source mobile development framework that allows use of standard web technologies

HTML5, CSS3, and javascript

for cross-platform development, apache cordova uses standard web technologies such as these three

• understanding the market and the user

• supporting multiple screen types

• maximizing app performance

• securing users

• remaining compatible with older versions

these are the five challenges in developing mobile apps

understanding the market and the user

a challenge in developing mobile apps:

• current market scenario must be studied, needs of target users must be addressed

supporting multiple screen types

a challenge in developing mobile apps:

• devices come in different sizes and shapes, which affects how you design screens and UI elements in apps

maximizing app performance

a challenge in developing mobile apps:

• performance of an app is affected by factors like battery life, multimedia content, and internet access

securing users

a challenge in developing mobile apps:

• users’ data is the most valuable asset

• sensitive info must be protected at all times

remaining compatible with other versions

a challenge in developing mobile apps:

• not all users may have upgraded or may be able to upgrade their devices

• setup

• development

• building and running

• debugging, profiling, and testing

• publishing

this is the sequence of the app development workflow (5 phases)

setup

a phase in app development workflow where:

• you install and setup your chosen IDE

• create an emulator and connect hardware devices which you can install your apps

development

a phase in app development workflow where:

• you write code, design UI, create resources for different device types

building and running

a phase in app development workflow where:

• you build your project into a package that you can install and run on the emulator or android-powered device

debugging, profiling, and testing

a phase in app development workflow where:

• it is the iterative phase in which you continue writing your app but with a focus on eliminating bugs and optimizing app performance

publishing

a phase in app development workflow where:

• the app is configured and built for release and distributed to users
