console market drawer_menu.java:204 a:

`mdrawerlayout.opendrawer(mdrawerlist);`

please help , regards!

try alter onoptionsitemselected method:

@override public boolean onoptionsitemselected(menuitem item) { // pass event actionbardrawertoggle, if returns // true, has handled app icon touch event if (mdrawertoggle.onoptionsitemselected(item)) { homecoming true; } // handle other action bar items... homecoming super.onoptionsitemselected(item); }

that should work.
