I'm developing an app in android and I have to support many different screen sizes and density. So i've created different a folder for layout : layout and layout-large.
For a normal screen size I have these drawable folders: mdpi(with a 320x480 image in it), hdpi (with a 480x800 image in it), and xhdpi (with a 640x960 image in it), but I also need a mdpi for a xlarge size screen. Should I create a drawable-large-mdpi and then put my image (480x800) in there?
Anyways I tried to do that and it seems to work just fine.
On my manifest I have:
<supports-screens android:resizeable="true"
android:smallScreens="true"
android:normalScreens="true"
android:largeScreens="true"
android:xlargeScreens="true"
android:anyDensity="true"/>
I'm using three different emulators:
4.0" WVGA (480X800: hdpi),
3.2" HVGA slider (ADP1) (320x480:mdpi), and
5.1" WVGA (480X800: mdpi)
My problem is that when I run it the size of the screen never match in any of the emulators. The width seems to get a bit smaller. It is never 100%
In the AVD manager when you start your AVD manually you get Launch options, there put a check mark against scale display to real size.
Setup your monitors dpi by clicking on the question mark.
Enter the monitor screen size and monitors resolution and then click on ok.
Now enter the screen size for your emulator in inches and then click on launch.
Do the same for all three emulators your testing the app against.

So I used the following code below to have my application to scale screen size on different android devices but when I am testing on my Nexus 7 its does not scale and its as if it was on a 4 inch screen. When I run it in the emulator on a 7 inch screen it works. Anything wrong with my manifest file?
<supports-screens
android:resizeable="true"
android:smallScreens="true"
android:largeScreens="true"
android:xlargeScreens="true"
android:normalScreens="true"
android:anyDensity="true"
/>
this code goes right before the "application" part right?
Ok, so what you have to know is that support-screens doesn't make your application look 'nice' on screens you are supporting (check this link). It just tells that users with such screens will be able to download your application, but it's up to you to make it display properly. You have to create layouts for specific screens on your own.
More about it you can read in Android's documentation: http://developer.android.com/guide/practices/screens_support.html
Basically, you have to properly name your directories in which layout files are stored in order to let Android know which one should it pick up for specific device. If for example your layout's file was "layout.xml" you should have:
/res/layout/layout.xml // Default layout
/res/layout-small/layout.xml // Small screens
/res/layout-large/layout.xml // Large screens
/res/layout-xlarge/layout.xml // Extra large screens
You can go even further and make also different layouts for portrait and landscape views by specyfing another keyword in directory's name:
/res/layout-small-land/layout.xml // Small screens, landscape view
/res/layout-small-portrait/layout.xml // Small screens, portrait view
Remember that tags order is important, so you can't write layout-portrait-small.
Use Relative layout it will solve most of your problem .Additional use Folder name with given below
the way i am dealing with multiple screen is this way and its working fine.....if any one has improved wayso do guide me
Screen size 480x800
layout-normal-hdpi-480x800

Screen size Galaxy Nexus--- though its size is 1280x720 but in actual due to system bar its dimension(screen size) differs
layout-normal-xhdpi

I have requirement to support all screen sizes on Android (Phones and Tablets). I have a set of images with resolutions 1280x720 and 2560x1600.
Question
How to name drawable and layout folders, so that these images are scaled correctly for all resolutions(if possible) ?
I'm clear that the question has been asked very often, but all I can find are half answers. I tried to create drawable folders with names:
drawable-xlarge-mdpi - for 1200X800
drawable-xlarge-xhdpi - for 2560X1600
And for layout, with names:
layout-xlarge-mdpi - for 1280x720
layout-xlarge-xhdpi - for 25601600
And added a manifest entry:
<supports-screens
android:anyDensity="true"
android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true" />
But now, it works only for tablets. On phones it always fails with error.
I found an answer here:
Drawables for qHD resolution
As I understand, all scaling occurs through code. But can anyone explain to me how to scale the image in the code with a resolution of 1280x720 and 2560x1600 and in which folder are to be placed in ?
I have read:
Application Skeleton to support multiple screen
Android : App support for multiple tablet screen resolutions
http://developer.android.com/guide/practices/screens_support.html
Android: support multiple screens
and many more.
I'm developing an application and i need it to fit all screen sizes and densities.
I created 4 folders for the resources (drawable-ldpi,drawable-mdpi,drawable-hdpi,drawable-xhdpi) and 4 xml layouts. But i'm confused a little about many points:
1- If I have a Samsung Galaxy tab 10.1 (mdpi screen) with a 1280 x 800 screen size and a Samsung Gio (mdpi screen) with a 320 x 480 screen size, how can I make the "layout-mdpi" folder including the xml layout file for medium dpi, fits these 2 devices having the same dpi but 2 different screen sizes (Galaxy tab is much bigger than Samsung Gio)?
2- I'm creating my png's using Photoshop, these png's must be saved with 320dpi,160dpi,240dpi..? Or all the resources must be saved in 72 dpi but different sizes?
3- I tested a star icon on my Samsung Galaxy tab 10.1 (mdpi screen) having 32x32px size, dunno why my icon is blurred!
You have to make all 4 different sizes images and put that images according to folder.And also set the property in menifest like this.
<supports-screens
android:anyDensity="true"
android:largeScreens="true"
android:normalScreens="true"
android:smallScreens="true" />
On Xoom tablet i am getting density value 1.0. Is there anything i have missed in manifest file to support 3.0 or greater os devices? Below is the code snippet to print the density value on tablet.
System.out.println("******==="+getResources().getDisplayMetrics().density
+"===widht=="+getResources().getDisplayMetrics().widthPixels
+"===height=="+getResources().getDisplayMetrics().heightPixels
+"====="+getResources().getDisplayMetrics().toString());
I have also added all supported screens set to true but still getting density value wrong.
<supports-screens android:resizeable="true" android:smallScreens="true"
android:normalScreens="true" android:largeScreens="true"
android:xlargeScreens="true" android:anyDensity="true" />
Anybody have any ideas on this?
Have a look to the Android doc density:
The logical density of the display. This is a scaling factor for the Density Independent Pixel unit, where one DIP is one pixel on an approximately 160 dpi screen (for example a 240x320, 1.5"x2" screen), providing the baseline of the system's display. Thus on a 160dpi screen this density value will be 1; on a 120 dpi screen it would be .75; etc.
This value does not exactly follow the real screen size (as given by xdpi and ydpi, but rather is used to scale the size of the overall UI in steps based on gross changes in the display dpi. For example, a 240x320 screen will have a density of 1 even if its width is 1.8", 1.3", etc. However, if the screen resolution is increased to 320x480 but the screen size remained 1.5"x2" then the density would be increased (probably to 1.5).
