mobile - android getDrawable() doesn't run -


i trying make app turn on mobile data on click. however, requires detect if mobile data on. if on, data1.png displayed else data0.png. however, reason not changing. test 2 running though. (wdata image button) code:

      connectivitymanager cm = (connectivitymanager) getapplicationcontext().getsystemservice(context.connectivity_service);     try {         class cmclass = class.forname(cm.getclass().getname());         method method = cmclass.getdeclaredmethod("getmobiledataenabled");         method.setaccessible(true); // make method callable         // setting "mobile data"         mobenabled = (boolean)method.invoke(cm);     } catch (exception e) {         // problem accessible private api         // todo whatever error handling want here     }     toast.maketext(mainactivity.this, ""+mobenabled, toast.length_short).show();

if mobile data enabled, returns true.

    if(mobenabled){         wdata1=getresources().getdrawable(r.drawable.data1);         toast.maketext(mainactivity.this, ":test 1:"+mobenabled, toast.length_short).show(); //runs          wdata.setimagedrawable(wdata1);// doesn't set      }else{         wdata1 =                 getresources().getdrawable(r.drawable.data0);         toast.maketext(mainactivity.this, ":test 2:"+mobenabled, toast.length_short).show();          wdata.setimagedrawable(wdata1);      }

i have used drawable wdata1 in other areas:

        wdata.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {             if(mobiledataenabled(getapplicationcontext())){                 setmobiledataenabled(getapplicationcontext(), false);                 wdata1 =                         getresources().getdrawable(r.drawable.data0);                 amobiledataenabled = false;                }else{                 setmobiledataenabled(getapplicationcontext(),true);                 wdata1 =                         getresources().getdrawable(r.drawable.data1);                 amobiledataenabled = true;              }             wdata.setimagedrawable(wdata1);         }     });

and in onresume() method:

   if( amobiledataenabled){         wdata1 =                 getresources().getdrawable(r.drawable.data1);         wdata.setimagedrawable(wdata1);      }else {         wdata1 =                 getresources().getdrawable(r.drawable.data0);        wdata.setimagedrawable(wdata1);     }

after setting drawable else, try calling wdata.invalidatedrawable(wdata1); right afterwards indicate needs refreshed.
