Problems on Adding More than One Material Drawer Activity to Same Project

[Baneeishaque]

I got these warnings on adding more than one Material Drawer Activity to Same Project, and i am afraid it will generate error and that must be corrected manually...

Ignoring conflict for the value: navigation_drawer_width wanted: "<dimen name="navigation_drawer_width">240dp</dimen>" but it already is: "<dimen name="navigation_drawer_width">320dp</dimen>" in the file: dimens.xml

The following file could not be created since it already exists: styles.xml

The following file could not be created since it already exists: row_selector.xml

The following file could not be created since it already exists: drawer_row.xml

The following file could not be created since it already exists: toolbar_default.xml

The following file could not be created since it already exists: NavigationDrawerFragment.java

If you proceed the resulting project may not compile or not work as intended.
