thank in advance

the first icon supposed drawer icon (aka hamburger). replaced launcher icon

 mactionbardrawertoggle = new actionbardrawertoggle(                 this,                  /* host activity */                 mdrawerlayout,         /* drawerlayout object */                 r.drawable.r.drawable.ic_launcher,  /* nav drawer icon replace 'up' caret */                 r.string.drawer_opened,  /* "open drawer" description */                 r.string.drawer_closed  /* "close drawer" description */                 )  

replace r.drawable.ic_launcher actual drawer icon resource in code above.
