This quote was taken from an official Android blog post ( http://android-developers.blogspot.com/2011/07/new-tools-for-managing-screen-sizes.html ):
"The original Samsung Galaxy Tab is an interesting case. Physically it is a 1024x600 7” screen and thus classified as “large”. However the device configures its screen as hdpi, which means after applying the appropriate ⅔ scaling factor the actual space on the screen is 682dp x 400dp. This actually moves it out of the “large” bucket and into a “normal” screen size. The Tab actually reports that it is “large”; this was a mistake in the framework’s computation of the size for that device that we made. Today no devices should ship like this." I don't quite understand this. If I do the math, dp = px / (dpi/160) The original Galaxy Tab has a PPI of 170, so: 1024 / (170/160) = ~964 dp 600 / (170/160) = ~565 dp Hence the original Galaxy Tab is 964x565 in dp units. This puts it in the "large" category, which was also originally calculated by the framework but was said to be a "mistake". Why? And how in the world do they get a 2/3 scaling factor? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
