How to make a String array case insensitive in Android -

i creating application read nfc tag , text of tag against string array see if there. works if tag case sensitive correct e.g. 'test', not 'test'. have tried various methods haven't worked. please @ code , see best solution me.

here relevant code:

string[] dd;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      dd = getresources().getstringarray(r.array.device_description);  }  @override     protected void onpostexecute(string result) {         if (result != null) {             if(arrays.aslist(dd).contains(result)) {             vibrator v = (vibrator)getsystemservice(context.vibrator_service);             v.vibrate(800);             //mtext.settext("read content: " + result);             intent newintent = new intent(getapplicationcontext(), tabstest.class);             bundle bundle1 = new bundle();             bundle1.putstring("key", result);             newintent.putextras(bundle1);             startactivity(newintent);             toast.maketext(getapplicationcontext(), "nfc tag written successfully!", toast.length_short).show();             }             else{                 toast.maketext(getapplicationcontext(), result + " not in device description!", toast.length_short).show();             }         }     } 

simple array search can it:

public static boolean doesarraycontain(string[] array, string text) {     (string element : array)         if(element != null && element.equalsignorecase(text)) {              return true;         }     }     return false; } 

and can call this:

doescontain(dd, result);
