how to design application UI for all resolutions in android

I am working on android application for my embedded project and I am very new to android. I have developed UI which should be suitable for all kind of screens (all resolution) in android.

Below is my code for all kind of resolution:

      if ( ((width>=240)&&(width<=320))&&((height>=320)&&(height<=480)) )
    {
        setContentView(R.layout.xsmall_layout);
    }
    else if( ((width>=360)&&(width<=480))&&((height>=640)&&(height<=720)) )
    {
        setContentView(R.layout.small_layout);
    }
    else if ( ((width>=480)&&(width<=540))&&((height>720)&&(height<=960)) )
    {
        setContentView(R.layout.medium_layout);
    }
    else if ( ((width>540)&&(width<=800))&&((height>=1024)&&(height<=1280)) )
    {
        setContentView(R.layout.vlarger_layout);        
    }
    else if ( ((width>800)&&(width<=1080))&&((height>=1280)&&(height<=1920)) )
    {
        setContentView(R.layout.x_vlarger_layout);
    }
    else if ( ((width>=800)&&(width<=1024))&&((height>=480)&&(height<600)) )
    {
        setContentView(R.layout.wlarger_layout);
    }
    else if ( ((width>=1024)&&(width<=1280))&&((height>=600)&&(height<=800)) )
    {
        setContentView(R.layout.x_wlarger_layout);
    }
    else if ( ((width>=1280)&&(width<=2560))&&((height>800)&&(height<=1600)) )
    {
        setContentView(R.layout.xx_wlarger_layout);
    }

Its working fine, but is it a good practice ? And in my pc(Intel Dual core, 2GB RAM), for the last resolution in the code is not working. I tried 1920x1200 and 2560x1600 . Android emulator is only not running. simply its coming black screen. Is this my PC problem or what..? Help me seniors......

Instead of that you can create different layout folder inside your res folder like:

layout-land
layout-large
layout-large-land
layout-xlarge
layout-xlarge-land

Keep the name of xml layout file same in every folder but you can mention different dimensions value.

Anyway, here is the test case you can do:

  1. Create a folder layout-large
  2. copy main.xml file and paste inside layout-large folder
  3. Change text size of TextView with some random values.
  4. Load app inside different density emulators. Enjoy !!

Please refer this one: http://developer.android.com/guide/practices/screens_support.html

In this Documentation they have clearly explained about all supporting screen resolution and dpi.

Hi Mars try like this http://developer.android.com/guide/practices/screens_support.html

Here they created these layout folders inside res

and puted same xml file to each layout:

layout


         layout-small
                        layout-large
                                         layout-xlarge

this thing ll take care for screen size.

i.e for table,smartphones etc
