java - Get bundle values in Android -

-

i'm still confused why i'm having error getting values bundle of main activity.

so, here's code snippet:

level1.class

chronometer chrono; chrono = (chronometer)findviewbyid(r.id.chronometer1); chrono.start();  long timeelapsed = systemclock.elapsedrealtime() - chrono.getbase(); int hours = (int) (timeelapsed / 3600000); int minutes = (int) (timeelapsed - hours * 3600000) / 60000; int seconds = (int) (timeelapsed - hours * 3600000 - minutes * 60000) / 1000;  intent lvl1 = new intent(getapplicationcontext(), finish.class);     bundle time1 = new bundle(); time1.putint("hour1", hours); time1.putint("minutes1", minutes); time1.putint("seconds1", seconds);  lvl1.putextras(time1);

and finish.class: (inside oncreate method)

textview set1;  set1 = (textview) findviewbyid (r.id.time1);  bundle time1 = getintent().getextras(); int hrs = time1.getint("hour1"); int min = time1.getint("minutes1");  int sec = time1.getint("seconds1");   set1.settext(hrs + ":" + min + ":" + sec);

could tell me why i'm having errors?

note: error in line 30, int hrs = time1.getint("hour1");.

you need debug code , put break points bundle intent check value in bundle. without doing guess ours.
