Android - Setting for Tablets

问题:

I am pretty new to Android. I wanted to know that if i want to design a tablet application then what changes i want make in the existing code which i designed for normal phone.

I did the Research and found,

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

and in Manifest

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

Is it all done?? or I want to change something other than this??

You need to create new layout files for tablet versions, Java part is enough but layouts and image drawables are the main things you need.

Go through Supporting Multiple Screens, Here you will have a complete idea about how to create UI supporting Tablets and their res folders.

For application to be worked, this is enough. But you should take care the size of the application When you are adding images to drawable folders it will increase your project size. So if you are using same images for all screens put that image in drawable folder. It will pick automatically to all screens, and if you want different image for different screen size put in different layout folders. You can make different layouts according to screen size to be fitted. The android will automatically pickup the proper xml files.
