android - how to define different activity's attribute for phone and tablet in AndroidManefist.xml?

Question

I have a activity, it has attribute in AndroidManefest.xml:

android:windowSoftInputMode="adjustResize"

but this attribute will introuce some performance in tablet, so I want change it to:

android:windowSoftInputMode="adjustPan"

I think if we can define a variable in res/values, which is different for phone and tablet. then apply this value AndroidManefist as below:

android:windowSoftInputMode="someVlaueDefineInResources"
