android - Resume old activity by passing new data in bundle -

i have couple of activities , b, c. activity starts b , b starts c , on. in app have set navigation drawer allows users go activity a. when user goes activity have passed flags don't restart activity resumes it.

intent = new intent(activity, a.class); intent.setflags(intent.flag_activity_clear_top | intent.flag_activity_single_top);

now m trying pass info using bundles.

bundle.putint("selectedtab", featured_coupons); intent.putextras(bundle);

but in activity bundle null.

if(bundle != null) { if(bundle.containskey("selectedtab")) { int tab = bundle.getint("selectedtab"); } }

you're going things in wrong way.

if want set integer intent extras don't this...

bundle.putint("selectedtab", featured_coupons); intent.putextras(bundle);

from docs putextras(bundle extras)...

add set of extended info intent. the keys must include bundle prefix, illustration app com.android.contacts utilize names "com.android.contacts.showall".

instead use...

intent.putextra("selectedtab", featured_coupons);

this isn't real cause of problem however. sumit uppal mentions, should implement onnewintent(intent intent) in activity a. can utilize set 'current' intent new intent...

@override protected void onnewintent(intent intent) { if (intent != null) setintent(intent); }

then in onresume() can use...

intent intent = getintent();

...and bundle intent.
