  • app capabilities depend on the browser in use
17
Q

how does native apps differ to hybrid apps

A
  1. platform specific
  2. compiled language
  3. access to device hardware
  4. platform frameworks
18
Q

how does hybrid apps differ to native apps

A
  1. cross platform
  2. scripting/compiled
  3. plugins/native modules
  4. web frameworks
19
Q

Why Choose the Hybrid/Cross-platform Approach?

A

One problem with native mobile application development is that it requires a highly specialized skill set. Although there are large and vibrant developer communities for C and Java – the language families that are mostly used for native development –, there are fewer developers who are knowledgeable in platform-specific versions of those languages and their respective IDEs.

20
Q

How Hybrid and Cross-platform Frameworks Work?

A
  • Hybrid apps leverage web technologies like HTML5/CSS/JavaScript, encapsulating them in a container for native-like functionality on devices. This approach enables quick mobile app development, utilizing existing web code. With improving mobile browser performance, hybrid development is a viable choice for web developers.
  • Progressive Web Apps (PWAs) use traditional web technologies and are accessed through browsers. They provide a responsive and app-like experience, merging the benefits of web and mobile app development.
  • Cross-platform frameworks like React Native and NativeScript offer native components for cross-platform code, while Flutter and Xamarin compile code to native, optimizing performance. Each framework caters to different development preferences and goals.
21
Q

There are two interlinked core components of a mobile application

A
  1. the mobile application “Front-End” that resides on the mobile device
  2. “Back-End” that supports the mobile front-end.
22
Q

mobile application cycle

A

develop
test
release
monitor
analyze

23
Q

cloud backend cycle

A

deploy
test
develop
analyze
monitor

24
Q

How Front-end ‘Talks’ to the Back-end?

A

The mobile front-end obtains the data from the back-end via a variety of service calls such as APIs.

25
Q

Why Developers Use a Cloud-backend?

A

Most mobile app developers may not be experts in setting up and managing the backend (the server-side) of their apps. To simplify their work, they often use backend-as-a-service providers. These services take care of the technical backend details like scalability and security, letting developers concentrate on building the actual features of their app without worrying about the complicated backend stuff. It’s like having someone else handle the tough behind-the-scenes work so developers can focus on making their app work well.

26
Q

How Mobile Aps Integrate with the Backend?

A

These back-end services are typically accessed through a variety of application programming interfaces, most commonly known as APIs

27
Q

A
  1. Essential services
  2. data services
  3. machine learning
28
Q
