I.
Android
design guideline [Chansuk Yang, Developer Relations]
1.
Message
1)
Basic advice
① targetSDK>19
(meaning use the most recent)
② change
support package level to support minimum Android OS level
2)
What’s new in KitKat
① Home
menu button: use app launcher icon as home menu button
② Visual
design: when design, comply with people’s mental model so users don’t need to
learn something new
③ Two
gestures: for zooming in and out, double touch or double touch drag
④ Full
screen mode: lean back mode (touching the screen in any way will bring navigation
and notification bar back into place.), immersive mode (swiping down from the
top or up from the bottom will bring notification bar or navigation bar
respectively)
3)
Android design pattern
① Action
Bar: app icon, view control, action buttons, action overflow
A
Suggestion: Android doesn’t recommend
customized Action Bar
② Up and
back difference
A
Up: higher category
B
Back: previous page or closing a pop-up
window
③ App
structure
A
Tab: fixed and scrollable tabs; needs to be
located at the top of the screen; needs to support swiping
B
Navigation Drawer: system bar needs to stay
④ Dialogue
and Toast principle
A
Principle
l How much
impact will the action bring to users? E.g. purchase brings a great impact
l Does
it allow users miss-click?
l Can
the result of the action returnable?
l Sufficient
user feedback to users? E.g. Facebook’s like button
B
Example: closing an app-> taking too
much time-> consider using Dialogue window
⑤ Notification:
utilize expand and contract option
4)
Responsive design
① Need
to support tablet
② Use DP
(density-independent pixels) (e.g. 200 dp)
③ Resource
qualifier- provide different size icons
2.
Takeaway
1)
targetSDK>19 (meaning use the most
recent)
2)
Home menu button: use app launcher icon as
home menu button

Message

What does this mean?
① New
capabilities:
A
indexedDB: important technology to store
data (e.g. games)
B
Web Sockets: push data back and forth
client and server
C
requestAnimationFrame: synchronize animation
on screen (not wasting time compared to JavaScript)
D
SVG filters and Effecs: e.g. convolution blurs
E
H/W
accelerated rendering (e.g. <canvas>)
② Debugging
Features: Analyzing web traffic, monetizing
③ Hybrid
applications: Use native component, interfacing JavaScript to native
④ Compatibility
mode: Use targetSDK>19
⑤ Multi-threading
and thread blocking
⑥ Custom
URL Handling: URLs must conform to RFC 3986
⑦ Viewport
Changes
⑧
Styling
Changes

Sizes
are in CSS pixels instead of screen pixels
2)
Best
practices

New
AdMob- profitability, convenience and control [Siyoung Choi, PBS AdMob Lead]
1.
Message
1)
Best practice
① Why it
got popular:
A
YouTube video review (subscription 3 M)
B
Review: ## reviews
C
Community BBS
D
Siyoung’s insight: Low requirement, short
game time, free
② Ways
to purchase mobile app contents: Freemium, in-app purchase, download
③ 수익= 매출
- 비용
A
운영서버, 퍼블리싱, 분석도구, 마케팅채널, 보안솔루션, 결제솔루션
B
매출: DL x재방문율x결제율x ARPPU
C
매출
결정 변수: 마케팅x In app 설계x service balance x결제지원수단, 개인별 결제 한도
④ 모바일 광고: 사용자는
돈을 내지 않고 광고주가 대신 지불+손쉬운 적용, 안정적
수익, 적은 투자
2)
AdMob 특장점
① Reach
and scale: Google Play global target, localization languages
② Innovative
ads: 전면 동영상
등 creative
③ High
fill-rate: traffic이
수익화에 적용
3)
광고
수익의 규모는
① 계산: 10M
user, 노출율 90%, CPC 100 KRW, xxx -> 9M KRW
4)
New AdMob
① 편의성: 빨라진
지급주기, 앱 개발자에게 최적화 된 UI (수익화/홍보 지원), 앱 업데이트 없이
mediation, house ad 적용
② 수익성: 전환최적화
기능 (자동으로 단가 최적화), 수익 극대화 (mediation 활용- Optimize AdMob Network)
③ 컨트롤: 세분화된
필터링 (140여개 예. 경쟁사 광고 제외), 광고 심사 센터
5)
광고
수익화를 위한 적용 Tip
① Refresh
rate: 30~60 seconds
② 광고와 컨텐츠의 경계
③ Smart
banner 사용: portrait <-> landscape
④ 전면광고: 사용자
별로 노출횟수 조절, 사용자가 즐거울 때, user flow 끊기는
지점, 호출과 노출분리, 최신 SDK 사용, Google Analytics 사용
2.

Lesson Google learned
① need setup
experience to be easy
② need nothing
new to learn
③ need
to support cross platforms and devices
④ need
to support second screen (smartphone, tablet, laptop)- because 77% of the time
while watching a TV, second screen has been used; the bigger the screen, the
more YouTube people watch
2)
setup process: plug in-> connect to
Wi-Fi-> cast (bringing optimized resolution depending on screen size)
3)
benefit
① video
and audio cast to TV
② Chrome
web browser tab mirroring
2.
Takeaway
1)
Just add code from Cast SDK at
developer.google.com/chromecast into your smartphone, tablet and website
2)
Review the Cast UX requirements and
integrate
