Android share intent from intentservice -

i want share multiple images app other apps. on android's developer page, found:

intent shareintent = new intent();         shareintent.setaction(intent.action_send_multiple);         shareintent.putparcelablearraylistextra(intent.extra_stream, savedimages);         shareintent.settype("image/*");         startactivity(intent.createchooser(shareintent, "share images to..")); 

how can use code intentservice? when using sample code intentservice, app crashes logcat error:

calling startactivity outside of activity context requires flag flag_activity_new_task

so added

shareintent.setflags(intent.flag_activity_new_task); 

but still same error , app crashes.

how can use share intent intentservice?

this line of code

startactivity(intent.createchooser(shareintent, "share images to..")); 

that means create intent object used start dialog activity user choose activity handle shareintent. so, in case intent show chooser dialog activity need flag flag_activity_new_task
can try:

intent chooserintent = intent.createchooser(shareintent, "share images to.."); chooserintent.addflag(intent.flag_activity_new_task); startactivity(chooserintent);
