android - Return to activity after Action Input Method Settings -

i making custom keyboard app.
there button leads user app input method settings.
here intent:

startactivityforresult(new intent(settings.action_input_method_settings), 2000); 

now, there way return user activity after enables keyboard?
edit
there way set broadcastreceiver , register when user clicks "ok" button on warning window? , app can call super.onresume() resume activity.

so spawn intentservice listens changes @ same time launch settings menu. believe how swiftkey has done theirs.

public class myservice extends intentservice {      /**      * creates intentservice      */     public myservice() {         super("myservice");     }      @override     protected void onhandleintent(intent intent) {         string packagelocal = getpackagename();         boolean isinputdeviceenabled = false;         while(!isinputdeviceenabled) {             inputmethodmanager inputmethodmanager = (inputmethodmanager) getsystemservice(input_method_service);             list<inputmethodinfo> list = inputmethodmanager.getenabledinputmethodlist();              // check if our keyboard enabled input method             for(inputmethodinfo inputmethod : list) {                 string packagename = inputmethod.getpackagename();                 if(packagename.equals(packagelocal)) {                     isinputdeviceenabled = true;                 }             }         }          // open activity         intent newintent = new intent(this, mainactivity.class);         newintent.addflags(intent.flag_activity_new_task);         startactivity(newintent);     } }
