With these it helps Native layout XML files are converted to a binary form, and include resource IDs baked at build time.
However since all GUI elements can be instantiated at runtime, you could probably roll your own inflater with an XML parser and a bit of reflection.

It's better to have similar behaviors, under single Activity, but always prefer different Activities when behaviors differ.

fixed the issue. Will look into that further Whereas at the time of the post I did not have an opportunity to test out the proposition of the post, I have since had a chance to do so, and thus will answer my own question, since noone else has done so.
Yes, the following scenario works as expected (tested at API level 8):
code :
... <include layout="@layout/included"/> ...
<merge xmlns:android="http://schemas.android.com/apk/res/android">
    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="GENERIC included fragment"/>
</merge>
<merge xmlns:android="http://schemas.android.com/apk/res/android">
    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="LOW-DPI included fragment"/>
</merge>

hope this fix your issue You need to use Intent to switch between activities. Replace the following line in onClick() method of the MainActivity
code :
setContentView(R.layout.activity_second_screen);
startActivity(new Intent(MainActivity.this, SecondScreen.class));

This might help you instead of creating other layout folders, just maintain different dimension folders like :
values-sw320dp - 1dp
