17. Measurements
That’s a cool Icon you designed with a graphic tool. ( think 1 cell= 10px).
How you seen it on your pc

18. Measurements
Suppose your pc has a depth of 160px per inch which we call 160DPI Screen. Dpi= Dot per inch. Androids are
usually have more DPI(260-640DPI). Your icon -
~160 DPI (Feels ok  ) ~240 DPI ( Bit small but ok ) ~ 640DPI (Aw!can’t see it :o )

19. Possible Solutions?
• Vector!!! Maybe!! But How smartphones will understand what to show ?
• The web works with pixels but phones cant work with this thing only because
of large pixel density.
• We need density independent unit for that purpose.
• DP = DIP = Density Independent Pixel. ( Used for all type of graphics)
• SP = SIP = Scale Independent Pixel. ( Used for fonts )

20. Measurements
• 2:3:6:8 Scaling Ratio
• MDPI= 1x (~160 DPI)
• HDPI=1.5x(~240DPI)
• XHDPI= 2x(~320DPI)
• XXHDPI= 3x(~480DPI)
• XXXHDPI=4x(~640DPI)
• Example:
• 48*48px(~160DPI)
• 72*72px(~240DPI)
• 96*96px(~320DPI)
• 144*144px(~480DPI)
• 192*192px(~640DPI)

21. Icons
• They are like doors.
• Start Big, If possible vector.
• Common names are easy to implement
• Optimize with Optipng/pngcrush
• http://docs.phonegap.com/en/3.5.0/config_ref_images.md.html

22. Other things that makes difference
• Splashscreen.
• Actionbar/Toolbar.
• Navigation way.
• Using the best possible screen realestate

23. Will build one app and build it to all platform

24. Bad idea !/Way more to think off/
too much Challenge

25. Building Native things =>
easy. Less to think about

26. Tools
I don’t recommend this one
Intel's App Framework

27. Some apps to look onto
• Flipboard ( they made it cross platform )
• Instagram
• Health
• BBC
• Exfm
• Rormix
• Fruitsalad
• twist
• IGN Dominate
