android - Calling Activity from notification forces new task resulting in a "blank" activity -

i have app might receive force notification. force notification should start activity when user clicks on it. pretty standard. got working on emulator , on galaxy s4, nexus device giving me head ache.

at first got:

java.lang.securityexception: permission denial: start intent

on particular activity, "fixed" inserting android:exported="true" activity in manifest xml. not sure if right approach, couldn't find improve one.

now getting

​startactivity called non-activity context; forcing intent.flag_activity_new_task for: intent

activity gets started, these variables seem "null":

opponentusername = getintent().getextras().getstring("opponentusername"); gameid = getintent().getextras().getstring("gameid");

resulting in "empty" activity.

this how launch activity in broadcastreceiverclass:

notification n = new notification(icon, tickertext, when); intent intent = new intent(ctx, ss9chatactivity.class); intent.putextra("opponentusername", dataobject.getstring("oppo")); intent.putextra("gameid", dataobject.getstring("game")); pendingintent pi = pendingintent.getactivity(ctx, 0, intent, 0); n.setlatesteventinfo(ctx, "game", tickertext, pi); n.flags |= notification.flag_auto_cancel; n.defaults |= notification.default_vibrate; nm.notify(1, n);

what tried far is, inserting android:launchmode="singletop" in activity, didn't seem prepare it

so doing wrong here? why nexus devices different emulator , galaxy s4? there app works fine.

thanks in advance help!

singletop right answer. however, need implement onnewintent incoming intent not automatically set can retrieve values via getintent():

protected void onnewintent (intent intent) { setintent(intent); // rest of code can utilize getintent() before handleintent(); // should called oncreate }
