Android : How To Support Devices With Normal Screen - High Density Or Low Density?
Nov 15, 2010I read the official document about supporting multiple screens http://developer.android.com/guide/practices/screens_support.html
According to that document, I should just create different directories for different resolultion.
Now the question. How to support devices with normal screen and high density or low density?
I ask it because, there are two posibilities (WVGA800 (480x800) and WVGA854 (480x854)) and (WQVGA400 (240x400) and WQVGA432 (240x432)) and I don't know where to store some background images for them.
I would take drawable-normal-hdpi or drawable-normal-ldpi, but how to make difference between 480x800 and 480x854 or between 240x400 and 240x432?!

Samsung : Android Screen Density Compatibility On 1.5
Jun 17, 2010I'm getting ready to release my first application the marketplace. It's being written for devices running Android 1.5 and above, however there aren't any specific folders for the three different screen densities (I think those came around in 1.6). Should I make these folders myself? Where should I put image resources for the different densities and what should I put in my Manifest?
View 2 Replies View RelatedAndroid :: What Ratio Of Dp-to-pixel Change With Screen Density?
Feb 28, 2009I'm being confused by the 'screen density' concept in Android. I knwe that dpi (dot per inch) came from the printing device. 160 dpi means 160 dots in every inch on the paper. However, when dpi is used for the screen density, for example, what's mentioned '160 dpi screen' in Android document, what's the meaning? 160 pixels on every inch of the display?
As described in http://code.google.com/intl/zh-CN/android/reference/available-resourc..., 1 dip (density-independent pixel) means 1 pixel on a 160 dpi screen. Why does the ratio of dp-to-pixel not necessarily change with the screen density in direct proportion?
When the dpi is changed from 160 to 80, how many pixels will 1dp will take? 0.5?
I can hardly understand why dip/dp is introduced into Android.
Android ::Unlock Screen Programmatically In Droid?
Dec 24, 2009I am working on a remote automated test framework for Android based on JUnit (tests run outside android, interacting with code inside it). It's all working fairly well, but one issue I have is that when I automatically start a fresh emulator, the screen starts out locked. This appears to affect my tests being able to run, plus, I want to watch the tests run (buttons clicked, text typed, etc.). If I manually start an emulator and unlock its screen, all works well.
Is there a way to programmatically unlock the screen in Android? A Java API, a command line or shell command, etc. would all be fine. Barring that, perhaps there is a way to start an emulator unlocked?
Android :: Make ImageButton Automatically Scale Based On Screen Density?
Jan 12, 2010I have an image put on an ImageButton, which looks good on a mdpi (medium-dpi) screen. However, when the device has a hdpi (high-dpi) screen, the image is still pixel-by-pixel accurate, which look small on the device screen.How do I make such that the image (and therefore the ImageButton) scaled based on the density-independent pixels (dp or dip) instead of pixels?

Jun 9, 2010A lot of hay is being made over the iPhone4's 326 ppi screen density. I was just curious, for comparison purposes, what's the pixel density of the Evo screen? This would be an easy calculation to do if I knew what the horizontal and vertical dimensions of the screen were, but I can't seem to find that information anywhere.
If anyone knows the pixel density or even just the exact X and Y dimensions of the screen..

View 9 Replies View RelatedAndroid :: Android - Screen Resolution And Screen Density
Sep 27, 2010As per managing resources(images) in > Android 1.6 version, we need to keep different-resolutions image in Drawable-Hdpi, Drawable-Mdpi, Drawable-Lpi folder particularly.
And as per this page: http://developer.android.com/guide/practices/screens_support.html ,
In Low density section - there are three resolutions used: 240*320 , 240x400 , 240x432 for the Small screen, Normal Screen, Large Screen particularly.
same way for Medium density section - there are three resolutions used: 320x480 , 480x800 , 480x854 for the Small screen, Normal Screen, Large Screen particularly. and same way for High density ........
But i am confused here:
(1) How do i come to know that whether small, Normal or Large screen is used, i mean is there any way to know ?
(2) How do i come to know which type of density i am using ?
(3) And in Drawable-Hdpi, Drawable-Mdpi, Drawable-ldpi folder, which resolution's image we should keep particularly?

View 1 Replies View RelatedAndroid :: Android Multiple Screen Sizes With Same Density
Apr 14, 2010I'm confused regarding the densities. I see that with medium density, the screen resolution could be either 320x480, 480x800, or 480x854. So if I have an image thats 300px wide in the mdpi folder, how is it going to look the same size on all 3 different screen sizes (mainly 320x480 vs the other 2)? And by look the same size, I mean scale to be bigger or smaller depending upon the screen size.

Nov 25, 2010I don't know if anyone else is as addicted to a 200 LCD density as me but the LCD density changer app was causing FC like crazy. So I thought there had to be another way. It's real easy, and takes 5seconds to do...
1: open root explorer and go to /system
2: open the build prop and locate the line about half way down that says 'LCD density = 240.
3: change the value to 200 and save (it will automatically create a backup in case of a Rom issue)
4: reboot
I'm sure you can copy the build.prop file to your computer and edit and reinsert the file or use astro + god mode script on some Rom. Just be sure to make a backup as root explorer is the only one I know of that makes a backup automatically.You will notice the clock is smaller as well as a host of other great changes. I'm addicted to a smaller size but there are a few issues I've found.

Android :: Programmatically Enabling / Disabling Screen Rotations
Aug 5, 2010I have an app which displays a large amount of text for the user to read. I've found that when reading while lying down, I get annoyed that the screen rotates even though my head and the screen are aligned. I do not want to set this to be permanently in portrait mode, so I think this would preclude an approach of setting the android:screenOrientation="portrait" in the manifest. Ideally, I would like to enable/disable automatic orientation changes via a preference page.
View 1 Replies View RelatedAndroid :: How To Access Programmatically What Is Displayed In Lock Screen
Feb 15, 2010Today I am looking for a way to mimic the behavior I know from my HTC Hero's lock screen: the calendar and alarm clock can put text & drawables there to inform about an upcoming event or an expired alarm. The lock screen remains there in that it must be dragged down to dismiss the shown event and there might also be a Snooze button.
But, first question: is this default Android stuff or HTC Sense specific only??
Second question: If it is a common Android thing, why can't I find anything in Google's Android documentation for the topics "lockscreen" or "lock screen" that comes close to my question? Where's the API for it?
My problem is: I want to inform the user immediately - even if I try a standard notification, the user with a locked screen will have to unlock it and drag down the notifications list to see & clear what's going on. sigh Putting an endlessly playing notification sound there is a hassle as it takes at least two swipes down to stop the sound playing!
