No, it is not possible to programmatically change the application package. For device-specific display sizes you can create size-specific layouts as described in the guide and use getResources().getConfiguration() to programmatically choose specific code paths to execute.

"i use different layout for different size device's " means you just use dp/dip sizes or that you have completely different layouts for each screen size?

If you only used dp/dip units, then you can add a scalefactor to your code to get the matching coordinates. If you are using different layouts, it's much more difficult. Depending on how many different layout configurations you have, you could build seperate apk files and upload them parallel. The Market will handle the distribution of the matching files then.

Another way:

Create an installer app which checks the device configuration and downloads the device-specific package afterwards from a ftp/network resource.

After installation, delete the installer and the .apk file.
