The document details the fundamentals of mobile applications, emphasizing the Wireless Application Protocol (WAP), its key features like push content and GPRS. It explores various input methods, device capabilities (like geolocation and sensors), and web platforms for mobile development, including native, packaged, and hybrid applications. Additionally, it discusses tools and environments for mobile web development, emulators, and simulators used for testing applications across different devices.

2. WAP
Mobile Applications Mr. A. B. Momin, Assistant Professor, Department of CSE
➢Wireless Application Protocol (WAP)
- Application Layer Networks
- Allows the transportation of information between a device
and the Internet
- WAP has two main versions: 1.1, released in 1998, and 2.0,
released in 2002

3. WAP Key Points
Mobile Applications Mr. A. B. Momin, Assistant Professor, Department of CSE
- General Packet Radio Service (GPRS)
- Wireless Mark-up Language (WML) — an XML
- WAP browsers
- WAP Sites

4. WAP Push
Mobile Applications Mr. A. B. Momin, Assistant Professor, Department of CSE
- Allows content to be pushed to a mobile devices at any
time.
- A WAP Push is generally an SMS (Short Message Service)
message to a special port with a URL to content or a
website.
- Modern smartphone platforms support Push messages using
an operating system layer that is out of the scope of carriers,
working through TCP protocols.

5. Fragmentation
Mobile Applications Mr. A. B. Momin, Assistant Professor, Department of CSE
- Fragmentation in this context refers to how the market is
“fragmented” in pieces supporting different interfaces,
hardware, operating systems, and abilities offered to
developers.

6. Display
Mobile Applications Mr. A. B. Momin, Assistant Professor, Department of CSE
- Resolutions
How many pixels (width and height) are available on a given device?
- Aspect ratio
To solve the problem of having different-resolution devices in the same device category,
some mobile browsers support a feature called device pixel ratio.
- Pixel density ratio
A device’s aspect ratio is the ratio between its longer and shorter dimensions.
vertical (or portrait) and horizontal (or landscape) ratio

7. Input Methods

• Voice recognition

8. Features
Mobile Applications Mr. A. B. Momin, Assistant Professor, Department of CSE
• Geolocation
Many devices can detect the user’s geographical location using one or many technologies,
like GPS (Global Positioning System), A-GPS (Assisted GPS), WPS (Wi-Fi Positioning System), or
cell-based location tracking.
• Phone calls
Yes, mobile devices also make phone calls!
• Accelerometer
An accelerometer is a sensor that measures proper acceleration in three axes— x, y, and z—
and can be used for games and orientation purposes.
• Gyroscope
A gyroscope is a sensor that measures orientation based on the principles of angular
momentum. It can be used in conjunction with the accelerometer.
• Magnetometer
A magnetometer is a sensor that measures the direction of magnetic fields and can be used
as a digital compass.
• Application installation
Many devices allow the user to download and install applications over the air (OTA).
This means that we can serve applications to a device from our websites.

13. Web View
Mobile Applications Mr. A. B. Momin, Assistant Professor, Department of CSE
• A native application is compiled and signed using official
SDKs.
• Non web programming languages, such as C, Objective-C,
Java, or C#.
• “Almost every native mobile platform includes a control or
component that allows web content to be embedded inside
a native application, this type of component is called as
Web View.”
Examples of web views in action include most social networking applications for
smartphones and tablets. When you find a post or tweet with a link to the Web, these
applications open a web view for you to see this web page inside the social app, not in
the browser.

14. Web View Example

that usually uses a full-screen web view as the whole
application container.
• The whole application is developed using web technologies
(HTML, CSS, JavaScript).
• It is packaged and compiled as a native application.
• After compilation of native application using any SDK is
called as packaged app.
