Support-Screens in Manifest File

Question

This is my code in my android manifest file.

supports-screens android:resizeable="true"
              android:smallScreens="true"
              android:normalScreens="true"
              android:largeScreens="true"
              android:xlargeScreens="true"
              android:anyDensity="true"

What I understand from supportscreens is that it can be used to simply fit the app screen onto the multiple screen sizes done by resizing it and stretching the image. However, I don't see any difference with or without this code. Can anyone help me?

Just Like this:

 /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  // Ex

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.

And in last add this code to your manifest file:

<supports-screens 
    android:resizeable="true"
    android:smallScreens="true" 
    android:largeScreens="true"
    android:xlargeScreens="true"  
    android:normalScreens="true" 
    android:anyDensity="true"/>

Please have a look at the Android Training site for "Designing for Multiple Screens"

Okay thanks man! So do I have to manually write any code in manifest other than the supports-screens, or does the program automatically decide which layout folder to use depending on the screen size of the device?

Yes.....after implenting this, you don't to do anything whenever you run application in any device accroding to that screen size that layout called...

@ShaniGoriwal after creating those different folders do i need to add anything in those folders or simply make them empty?

android:resizeable is deprecated.

what about if we don't create 4 layout folder but add those lines to manifest. Would that be a problem?
