A 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..

I'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.
I 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?!
I have some png files that I am applying a color to. The color changes depending on a user selection. I change the color via 3 RGB values set from another method. The png files are a random shape with full transparency outside the shape. I don't want to modify the transparency, only the RGB value. Currently, I'm setting the RGB values pixel by pixel (see code below).I've come to realize this is incredibly slow and possibly just not efficient enough do in an application. Is there a better way I could do this? Here is what I am currently doing. You can see that the pixel array is enormous for an image that takes up a decent part of the screen

Can you please tell me how can I specify dimension of layout for different density of screen?
i.e. the layout are the same across different densities, but some dimension are different.
how can I do that?
I'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 Relatednote: this is an artist rendition because my digital camera is terrible and i couldn't figure out how to get the dust in the shot. but it looks just like this. it's a black speck under the screen that can only be seen on bright surfaces and only if you are looking at the screen head on. i'm not sure if it might be a dead pixel. i can certainly live with this problem although i'd prefer if it wasn't there.
1. is this a dead pixel or dust?
2. how do i fix this, can i just exchange it at the vzw store whenever they stop being sold out?
I want each pixel on the screen to flash between red, blue, green, white, and black but independently of each other. Is this possible? I have been searching everywhere with out any luck. Any help on where to start would be greatly appreciated.
View 1 Replies View RelatedI've had a HTC Evo now for 2/3 weeks, and I love it! But over the last few days it's started to act funny....
What it's doing is lets say I unlock the phone and have it laying on my desk, in the past it would show the screen in portrait orientation....but over the lat 2/3 days its been jumping to landscape and I have to pick up the phone, tilt it to get it back to portrait, and if I lay it back down it will go back to landscape.
This is mainly annoying when checking emails/texts/etc, but also if I am on the train and holding it near my waste, depending on the angle it will bounce back and forth from portrait to landscape!
I originally did a reformat when I bought it, and I am going to do it again shortly to see if that helps....just wondering if anyone else had this problem and if it's fixable (and yes i do want auto rotation)....
My phone has a few other problems such as minor light leakage, and a dead pixel (which I was going to look past and keep the phone)...so if this is something wrong with the hardware it would be a pretty good reason to get a replacement within my 30 days....
I 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?

I see the screen when device turns on then i hear the boot animation but i cannot see the boot animation. I have cwm accesable on the phone and can also boot it into fastboot mode. I have a nandroid backup when the phone used to work but its not restoring it says md5 mismatch.
There's no stock rom for my phone available but i have extracted the system folder from nandroid backup.
As 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 2 Replies View RelatedI'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.

View 49 Replies View RelatedI'm running cm6 and the Galaxy S Theme. I would like to run my density at 160 because I really love how tiny the icons look on my screen. However, when I run the density to that setting my notification menu bar no longer stretches across the top of the screen, it appears as a small square in the left hand corner. I also have the same problem in the market place, where the grey background should stretch across behind where it says "market". My friend runs his at 160 and has no problems like this, however he is not running cm6 or the theme I am. So, while it doesn't really narrow it down any, I'm sure the problem is in one of the two, more likely the theme in my mind. Any idea's how I can fix or repair this problem?

View 24 Replies View RelatedHas everyone seen that you can change the LCD density on the Desire? (Well, on all Android handsets really). It simulates a higher resolution, fits more text on screen etc. There's an app on the market which does it, although it won't work on the Desire unless you're S-OFF. All you need to do is extract the build.prop file from /system to your PC (in recovery, use ADB PULL), and using a text editor change the value of LCD Density from original 240 to 200, then ADB push it back and reboot. I'm *really* pleased with the result. Combined with Launcher Pro I've a whole new feel to my phone...

I haven't been able to fix it myself. I have already done the factory reset but that didn't work. I used the ROM toolbox. Now my sgy is like in a zoomed state. Large fonts, cannot unlock and change to default setting. I cannot click the android icon that can be seen when you reboot your phone and did the factory reset. assistance is badly needed. i have browsed through the theads, but this issue has not been addressed.
View 1 Replies View RelatedSo when I bought the Evo, the first unit had a crack on the bottom of the LCD, then I got a replacement that same day and it had a dead pixel.

This is a dead pixel, not a stuck one. I can only see it on a white background and its a black dot. Any thoughts?
I'm not even concerned with the camera per se. I want at the closest thing to the display screen. Meaning: it could even be the desktop the user is looking at, completw w/ the background and the icons she moves back and forth.
Let's say, at time t=1 sec, the app goes to pixel (78, 300) on that display and obtains its value. What may be at (78, 300) could be a portion of the icon or some speck of tree leaf on the photo being used as desktop background.
I'm familiar with BitmapFactory.decodeFile() for getting at the pixel contents of a file. But what about the display?

Running Incredible with Froyo. I rooted using Unrevoked3, but I forgot to make the nandroid backup, I guess. the LCD Changer app has my reboot looping. After the very first HTC Incredible screen it goes totally white and I just hear the "Droid" voice(plays when the red droid eye comes up on screen normally" nothing but white and the voice just repeats after the screen flashes every minute or so. Tried applying the update.zip that was linked to on the developers blog, but no luck. Any ideas? I even tried resetting to factory defaults, formatted everything, basically. Lost a great of data, I'm afraid, but I just want my phone back.

View 35 Replies View RelatedI 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.
