Android :: Applications And Screen Resolutions
Apr 4, 2010
Android allows for the UI of its OS to be optimized for various screen resolutions and aspect ratios. How about apps? Do they share a common link between the OS and themselves for this resolution optimization? I'm curious in terms of tablets. If you have a 800x480 screen in 16:9. The OS's UI looks great but what about those apps? Is it strictly on an app to app basis how they will be presented? Hope the question is clear.

I have a class that extends LinearLayout and handles drawing to the screen. (it is in the early stages) How would I go about determining the dimensions of a screen and resizing the images, etc., that this class is drawing to the screen on the fly before actually drawing them to the screen?
What I'm trying to accomplish is support for devices that have varying screen dimensions and resolutions from the same code base, with each device being scaled properly.

I am a current iPhone 3gs user migrating over to Android this Friday and getting the Evo 4g. Now, all iPhone/iPod touch screen sizes are the same and all the hardware specs are the same for the most part, but with Android you all kinds of resolutions, screen sizes, processors, etc etc...
Are all apps made for Android stretched to accomodate bigger screen sizes? For instance, I have played with my friend's Droid on Verizon and the screen is 3.7" at a resolution of 854x480 and he has showed me games on it like Gameloft's NOVA which is a full 3D first person shooter. So his phone essentially has a bigger resolution slightly than the HTC EVO 4G but smaller screen size (3.7" vs. 4.3"). So would the same game be stretched to fit my phone?
I'm wondering with different apps, are there any conflicts in relation to different spec phones?

i have completed my app for the 320x480 size and i don't give two cents about dpi or density, but i want this to work on the larger formats to and i have new artwork for those resolutions for my entire app. Is there an elegant way to set up my xml layouts and artwork around resolution only? In other words a "normal" screen size could be 320x480 or it could also be 400x800 or 400x856 depending on the dpi.
where it specifically applies to only small normal screens with medium density?
how to i account for the 800 vs 854 height difference when clearly xml identifiers won't tell these two apart? My app does not use a lot of relative layout components as it is very heavy on the sprites which obviously have fixed 2D dimensions

I am currently working on an android app that is causing me some trouble. My app is heavily dependent on images that are fitted correctly to the screen they are being displayed on. Unfortunately things like the FWVGA/WVGA resolution difference 854 vs 800 is causing me some real problems, and that's aside from the other sizes/densieites and resolutions.
I don't know if I'm just missing the point here but how do I go about having my app display correctly on both the resolutions without either "squashing" my images or cutting bits off of giving me black bars etc?
There doesn't seem an immediately present solution where I can just have it display a different image automatically from the drawable folder for the right screen.
I have tried using displaymetrics but unless i have my manifest claim that it supports all screen sizes, the android OS will in fact "lie" to my app about hte current resolution.

I see on the Android SDK pages, it mentions some screen resolutions to expect on Android platforms:
Small screen
QVGA (240x320), 2.6"-3.0" diagonal
Normal screen
WQVGA (240x400), 3.2"-3.5" diagonal
FWQVGA (240x432), 3.5"-3.8" diagonal
HVGA (320x480), 3.0"-3.5" diagonal
WVGA (480x800), 3.3"-4.0" diagonal
FWVGA (480x854), 3.5"-4.0" diagonal
Large screen
WVGA (480x800), 4.8"-5.5" diagonal
FWVGA (480x854), 5.0"-5.8" diagonal
Obviously, testing an app you want to sell on all these resolutions is going to be a pain. Is there any data on what percent of android phones being used use the above resolutions? My hope is that there's only really 3 or so popular resolutions...

I have a texture.png which I would like to tile, to create a textured background for my window.
Will I run into any problems with different screen resolutions?
If so, what is the best way to support a textured background for multiple devices?
Should I have 1 image instead? How large should it be?

I am in middle of learning application development. I have created an application in 2.2 and tested that in my HTC Nexus One device. I looks like fine. My client testing same application setup in his device (Droid2). I don't have that device to test.
He said there are some font sizes are vary and button alignments are missing. When I testing in my device everything looks fine. So, I need to test my application in Simulator which resembles like Droid2 device. Can anyone tell me how to create emulator and setup like Droid2. And also, is there any need to adjust my code or anything in manifest file.

I had posted a similar thread a while back and received no feedback, so let me try to be more clear.I am able to use Androids components to build the most basic layouts, which include images, buttons, text areas, etc. These are like Android Lego! I can build the castle. BUT I want to design my own component, my own Lego, that draws on the screen and uses the available area that the Android components have not used. ie, I want to have a top layer of buttons, and the rest of the screen, whatever it is, I want to use to draw 2d graphics. So, I want to make my own Lego, and use it with the other Android Lego. However, I'm also trying to be a good developer and making this for whatever resolution is thrown my way. What is the best way to do this considering the deluge of different resolutions Android developers must cope with? Is there a way to do a table view and return the remaining screen size? Or, am I stuck making an entire new box of Lego here?

I have a written a game that works fine on the 'normal' 320x480 screen of my G1.
I tried it on a friends Xperia x10 and it leaves a large blank section on the right hand side of the screen. How do I fix this? I've read that I need to include an extra directory in res/drawable for different densities. How do I do this?

I have a button which I want to occupy 75% of the screen:
On a 480x800 resolution screen this would be 360 pixels wide.
On a 280x320 resolution screen this would be 210 pixels wide.
How do I go about specifying this in my layout XML file?
I understand there is a DIP unit of measurement, but does that also work to scale screen images for resolutions? What DIP measurement would I use for this, and do the images need to be saved at 160dpi.

For a while I'm wanting to create live wallpapers, after weeks of searching and weeks of trying out various things (The LWP creator found on XDA etc) I've figured out all of them are not really working with the latest phone's, and lastest screen resolutions.
How to create live wallpapers, for the latest screen resolutions, or just compatible with all.
What I want is to create a "Gif-like" android LWP.

With my Motorola Quench/Cliq XT the standard lock screen is a bit bland and requires the menu button to be pushed to unlock and I prefer a slide to unlock like many other phones has. However the problem is when I install advanced lock or lock 2.0 or some other locking app, it causes my camera button to wake the phone which gets pushed often while inside the holster case, the camera button doesn't wake the phone on stock. Does anyone know if there's a setting to disable the camera button function for such things?

I just got an Android phone on Sunday and I'm still learning what I'm doing. I found a thread on here for the Android Network Awards, and all of the apps have a 2-D barcode next to them. Clicking on it invokes a "market" protocol. I'm guessing that there may be some way for me to scan this barcode from my phone and install the app. Is that right? Presumably, I could also browse to the page from my phone and click on the "market://..." links, but scanning a barcode to install an app is just cool.

I have general question about Cupcake (or any other later relase): do you, when writing apps, consider running them on qvga device? although Dianne wrote here http://groups.google.com/group/android-developers/msg/73ded3ba1fe7139e that qvga is not supported i still see in Cupcake sdk qvga skins...
My question is: should i really forget about qvga or not?

I've recently tried several lock-screen disablers/changers:
* mylockforandroid
* SmartLock
* No lock
* Executive Asisstant
* Lock 2.0
And a few others. It was my impression that something is inherently broken with all of them: Lock screens would sometimes work as advertised, but sometimes they would revert to original.
For example, right now I am using Tasker to disable the lock screen, and while it works, mostly, now and then it keeps reverting to original lock screen. Now I am kinda suspicious if one of the original applications I installed failed to uninstall properly.
Anyone had similar experience with lock replacement apps? Is there a way for me to see who changes the lock screen? Or at least inspect the scheduled tasks? I'd rather not do a complete hard reset of the device.

I am new here and I came from Symbian and Linux, for all the phones I've used there are at least one application for screen capture and one for time clock synchronization, both are very useful and basic task we will do with a smartphone, but on the Android I found none that can work without a 'rooted' phone. I don't know how other phones do it, but I know the reason for a 'rooted' phone is to be able to access the framebuffer for screen capture for example and this may be risky, I suppose it is simply a sub-routine call to the BIOS will do without the need for a complete 'open access' system. I know there is a way to capture the screen without a rooted phone, but the phone must be connected to a PC and I feel this is dumb and inconvenient, I may be completely wrong about Android, please fill me in.

This may have been asked before but how do you keep the screen from going dim or off completely when you using apps? The only app that seems to keep the screen from going dim is Navigation. If I use an app like Google Maps it goes dim and then dark at the set time. I would like it to stay on specifically when it's got the charger hooked to it. It will only go dim with the charger on but I'd like it to stay bright. Or do I have to change my setting to "never turn off" everytime I want it to stay on?

Does anyone else's phone just go black (not off, just black screen) while browsing? Late at night ill be using my EVO browsing the App store. Ill download 2-4 apps and play around with them, keep what I like and uninstall what I dont. Ill read the news, use friend stream and read reddit. I am using wifi, no task killers, froyo, (problem existed with 2.1 as well), but for whatever reason my screen goes black.
The phone is not off, the 4 buttons at the bottom are lit up. Pressing the power button brings the screen back on but sometimes it just dies out to a black screen again. I've done a soft and hard reset both to no avail. Is anyone else having this problem? How many apps can the phone handle at one time?
