hi have problem buttom, have main drawer open main fragment, every time change fragment called addtobackstack(null) problem navigation drawer when im on second fragment , select fisrt option on drawer, fragment show properly, after press buttom , got :

i resolve issue with:
if (mview != null) { viewgroup parent = (viewgroup) mview.getparent(); if (parent != null) parent.removeview(mview); } try { } catch (inflateexception e) { e.printstacktrace(); }
