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

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: "240dp" but it already is: "320dp" 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.
```

Start by examining the template files named in the warning: dimens.xml, styles.xml, row_selector.xml, drawer_row.xml, toolbar_default.xml, and NavigationDrawerFragment.java. Reproduce adding more than one Material Drawer Activity, then trace how each generated activity handles shared resources. Done means multiple activities can be added without file or resource conflicts and the generated project compiles and works as intended.
