Android lock screen notification is not able to open Browser on double tapping -

my app sends out notification, opens browser given url on tapping. actually, wrapped intent sent broadcastreceiver, , broadcast receiver starts browser.

intent browserintent = new intent(intent.action_view, intent.getdata()); browserintent.addflags(intent.flag_activity_new_task); context.startactivity(showtaskintent); 

it works fine notification on pull-down notification bar, not lock screen notification. it's not able open browser on double tapping.

from log, can see activitymanager receives intent, , tries start broswer:

09-02 15:10:52.309 1536-1894/system_process i/activitymanager: start u0 {act=android.intent.action.view dat=https://www.thesun.co.uk/... flg=0x10000000 cmp=com.android.browser/.browseractivity} uid 10059 on display 0

but happened browser is

my assumption is: @ time, device still locked lock screen, when activitymanager delivers intent start browser, android system might have checks or mechanism not start activity.

has had such problem before? thanks!

i think bug in chrome, , have raised issue both android , chrome:

https://code.google.com/p/android/issues/detail?id=221940&can=4&colspec=id%20status%20priority%20owner%20summary%20stars%20reporter%20opened

https://bugs.chromium.org/p/chromium/issues/detail?id=645848&can=4&q=&colspec=id%20pri%20m%20stars%20releaseblock%20component%20status%20owner%20summary%20os%20modified

however, found workaround: use custom tabs instead of normal tabs can solve issue.

intent.putextra("android.support.customtabs.extra.session", context.getpackagename()); intent.putextra("android.support.customtabs.extra.extra_enable_instant_apps", true); 

add above extras force chrome use custom tabs.
