APK is copied to /data/app of root. Data related to apk is generated in /data/data/app_name

You could have got enough articles on this on StackExchange after searching, for example:

Hi and thanks rahul, this link (and figure) explain very well the details of building the apk, BUT it does not explain the details of the APK installation process, it only states for both running on an emulator and a device "...and install your apk on the device (emulator)..." I still need to understand what Anroid OS modifications occurr during an apk installation, which so far in the awesome thread, remains unanswered, please assist. – prakhar Dec 26 '12 at 05:11

Preinstalled applications are in

/system/app

folder. User installed applications are in /data/app. I guess you can't access unless you have a rooted phone. I don't have a non rooted phone here but try this code out:

public class Testing extends Activity {
    private static final String TAG = "TEST";
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        File appsDir = new File("/data/app");

        String[] files = appsDir.list();

        for (int i = 0 ; i < files.length ; i++ ) {
            Log.d(TAG, "File: "+files[i]);

        }
    }
