[android-developers] Re: Starting an activity with FLAG_ACTIVITY_MULTIPLE_TASK to see multiple instances
Here is an use case we are trying ..
Apk .. MyEmail
main -> Inbox
view -> composer
view -> msgview
If the above apk contains 3 activities ..
User launches the "MyEmail: and sees the Inbox ..
User selects one of the messages .. thus launching the "msgview"
activity ..
User goes back to home .. and launches .. composer directly .. ()
Now the user must be able to switch back and forth between "msgview"
and "composer" .. Note this composer window has no association with
the Inbox->msgview ..
One possible method is to launch the MyEmail in own task and launch
another activity (eg.composer) as a separate instance .. This is what
I was trying to show in the code above ..
I did read through the 'warning' in the docs of
FLAG_ACTIVITY_MULTIPLE_TASK usage. Assuming for now we use the
RecentAppsDialog(long key press) as the task switcher .. any
suggestions ?

Please please please don't use FLAG_ACTIVITY_MULTIPLE_TASK unless you really
know what you are doing. At the very least, you need to read and fully

You need to at least post the stack crawl of the error.
