CHAPTER 1 ■ ENHANCING ANDROID APPS: USING NEW MEDIA ASSETS

New Media Genres: Multimedia Pie Slices

There are a number of different types (or genres) of new media, and all of these are

supported in Java and JavaFX (which power Android, along with the Linux Kernel) as

well as in Android OS. These support adding what I like to call new media “assets” to the

Android application code. You’re familiar with most of them I imagine: digital images

like those on Pinterest or Instagram, or digital audio like that on Spotify or Pandora.

Digital video can be used to stream movies or your favorite television show. Less prolific

new media types include 2D vector or digital illustration media that looks like 2D

cartoons, and 3D vector, or interactive 3D media, like you see people using on popular

game consoles like Xbox to play sports or adventure games. All of these examples are

high-sensory user experiences, so adding new media assets or elements to your Android

application development process is how to take your app to the next level !

Separate Your App from the Crowd: New Media

The major advantage to incorporating new media assets into your Android application

development in Android Studio is the visual and aural “wow factor” that you can add to

an application. This sets it apart from other applications and generates a word-of-mouth

marketing effort on the behalf of your users, and that you will not have to pay for. This is

what I’d call a “windfall profit,” and it is what this book targets to bring to your Android

application development knowledge base and to your new media assets for Android

Studio content production. For example, where digital imagery is concerned, instead of

having a solid background color, use a subdued texture or a subtle color gradient, which is

actually digital illustration, as you’ll learn over the course (no pun intended) of this book.

Where digital audio is concerned, with custom audio user interface sounds for user

interaction feedback, users will feel like they’re more closely tied into, or are a part of,

your Android application. Digital audio can enhance the user experience more than you

are probably giving high-quality audio credit for!

Digital video and interactive 3D are more on the content production side of the

application enhancement spectrum, rather than on the user interface design side of

things; however, they are just as important. Digital video that is well optimized may play

back more smoothly via slower connections, and interactive 3D, or i3D, applications are

rare, other than popular 3D games.

Next let’s take a look at the new media file formats the Android operating system

includes. What I mean by “includes” is a decoder for the file format’s codec ( cod e-

dec ode) is actually a part of the Android OS, and already installed on the hardware!

Android Studio New Media Support: File Formats

The key to bridging your new media content production to your Android Studio development

environment is those new media file formats currently supported in Android 5 or later.

Most of them are supported in Android 4. Many of these are also supported in earlier

versions of Android, such as 1.6, 2.37, and 3.2. Devices running these versions of Android

are becoming hard to find; soon all you will have to worry about is 32-bit Android 4.4 and

CHAPTER 1 ■ ENHANCING ANDROID APPS: USING NEW MEDIA ASSETS

64-bit Android 5.4. Specialized versions of Android—such as the Android Wear, Android

TV, or Android Auto SDK—support these same new media file (data) formats and codecs.

So no worries there! Table

1-1 summarizes these popular new media file formats.

Table 1-1. Android New Media File Format Support by Version

New Media File Format New Media Genre Android OS Version Level

PNG8, PNG24, PNG32 Digital image All OS versions

JPEG Digital image All OS versions

WebP Digital image Android OS 4.0+

GIF Digital image All OS versions

SVG Digital illustration All OS versions

OpenGL 3D All OS versions

WebM (VP8, VP9) Digital video Android OS 2.3.3+

MPEG-4 Digital video & audio All OS versions

MPEG-3 Digital audio All OS versions

OGG Vorbis Digital audio All OS versions

FLAC Digital audio Android OS 3.1+

WAVE Digital audio All OS versions

AIFF Digital audio All OS versions

AMR Digital audio All OS versions

Android Studio digital image support currently includes JPEG, PNG, GIF, and WebP.

You’ll learn the attributes of each of these in Chapter

3 , which covers digital imagery

optimization, but I’m sure you know that JPEG is the most widely used digital image

format, the CompuServe GIF is the oldest digital image format, and that PNG (Portable

Network Graphics ) is the newest digital image format. WebP is the same codec as your

WebM video codec, except that it is compressing one frame, often called a “still” image.

Android Studio digital audio support currently includes MPEG4 Audio (M4A),

MPEG3 Audio (MP3), Free Lossless Audio Codec (FLAC), OGG Vorbis, Windows Wave

(WAV) Audio, Audio Interleaved File Format (AIFF) for Macintosh, and a number of

others. You’ll go over the attributes of each of these in Chapter

5 , which covers digital

audio data footprint optimization.

Android Studio digital video support currently includes MPEG4 AVC and WebM

(VP8 and VP9). Whereas the digital audio support is expansive, the digital video support

includes only two codec offerings—the same two that are supported in HTML5. Both

codec offerings are open source, as Google purchased ON2 and made the VP8 and VP9

(WebM) codecs open source. MPEG patents expire in 2027 (all of them), although some

have expired already. HTML5 and Android have licensed MPEG4, so you can use that in

Android. You’ll learn about each of these codecs in Chapter

7 , which covers digital video

data footprint optimization.

CHAPTER 1 ■ ENHANCING ANDROID APPS: USING NEW MEDIA ASSETS

Android Studio uses Scalable Vector Graphics (SVG) for its digital illustration

support; in fact, Java (via JavaFX) supports an entire library of classes that allow you

to create, read, render, and animate SVG digital illustration data. You’ll learn about

the attributes of each of these in Chapter

9 , when digital illustration data footprint

optimization is covered.

3D modeling and animation support OpenGL, as well as all the 3D data formats that

the OpenGL importers support, such as .FBX, .DAE (Collada), .3DS (3D Studio), .OBJ

(WaveFront), .X3D, .STL (Stereolithography), and other open 3D geometry formats. You’ll

find out about each of these i3D data formats in Chapter

10 , which covers 3D modeling,

rendering, and animation concepts.

Downloading and Installing Your Software

I’m going to take a few pages in the second half of the chapter to show you a

professional-level open source software package for each of the five new media genres

that are covered in this book. This is so that if you do not have a software package that

covers that type of new media development, you can download and install one that’s free

for commercial use and has all the professional features that a paid software package

features. You will be amazed at the value that these software packages provide once you

install and launch them.

Digital Image Editing and Compositing: GIMP

You need to have a digital imaging software package of one kind or another. If you do not

own any digital imaging software, you can use the free-for-commercial-use GIMP 2.8.14,

which is the current stable version, at least until GIMP 3.0 comes out some time in 2016.

To download GIMP 2.8.14, go to the

www.gimp.org web site, and click the orange

Download button; or alternately, click the Downloads link, seen on the right in Figure

1-1 .
