Creating multi-screen support app android

Question

I am creating a app in Android that must support multiple screens.

For this purpose i have read many answers and one which i like most is state that i can create different folders in res folder by following name,

For small screens layout-small,

For large screens layout-large,

For extra large screens layout-xlarge

and i have to create different layouts for different screens with same name. e.g mylayout.xml

and i have to put following code in manifest.xml file

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

and finally i just need to write following lines in my Activity file,

  setContentView(R.layout.mylayout);

Now when i run this app in different size screens it should acquire layouts from different folders as per screen resolution.

But this is not happening in my case.It takes only layout that defined in layout folder.

Please can some one explains me why this happening and how can i solve this issue so that my app can run effectively on all size screens.

Answer 1

Try out like:

• layout-sw320dp
• layout-sw480dp
• layout-sw600dp
• layout-sw720dp

instead of

• layout-small,
• layout-large etc...

Please refer below link:

http://developer.android.com/guide/practices/screens_support.html For Different screen size, The following is a list of resource directories in an application that provides different layout designs for different screen sizes and different bitmap drawables for small, medium, high, and extra high density screens. you could use different size of the layout files in res folder and also vary for drawable images based on the density..

  res/layout/my_layout.xml             // layout for normal screen size ("default")
  res/layout-small/my_layout.xml       // layout for small screen size
  res/layout-large/my_layout.xml       // layout for large screen size
  res/layout-xlarge/my_layout.xml      // layout for extra large screen size
  res/layout-xlarge-land/my_layout.xml // layout for extra large in landscape orientation

res/drawable-mdpi/my_icon.png // bitmap for medium density res/drawable-hdpi/my_icon.png // bitmap for high density res/drawable-xhdpi/my_icon.png // bitmap for extra high density

<compatible-screens>
    <screen
        android:screenDensity="ldpi"
        android:screenSize="small" />
    <screen
        android:screenDensity="mdpi"
        android:screenSize="normal" />
    <screen
        android:screenDensity="xhdpi"
        android:screenSize="large" />
    <screen
        android:screenDensity="xhdpi"
        android:screenSize="xlarge" />        
</compatible-screens>

And followed by any activity use this lines..

android:configChanges="orientation|screenSize|keyboardHidden"
