please remove duplicated

new drawerbuilder().withactivity(this).build(); 

which have in mainactivity, must .build() 1 drawer (and in cases .append() one)

the code of drawer make sure not 2 drawerlayout's inflated.

in addition checked url header image. 1 not exist. (http://www.api.androidhive.info/images/nav-menu-header-bg.jpg returns 404)
