Thank you for your detailed answer Blake B.,
First of all I understood that different Extras are not act as a
difference on PendingIntent comparison.
In the first option assigning a stub data element seems reasonable but
I did not like the approach to put not only irrelevant but also not
necessary data on each intent call to distinguish them.
With the second approach, assigning FLAG_CANCEL_CURRENT flag to the
PendingIntent worked well on button calls but did not work on
notification calls. I received "Sending contentIntent failed:
android.app.PendingIntent$CanceledException" error in logcat on each
different PendingIntent start. I have seen a bug report is made about
this issue(#13) on android-astrid.
In the issue, it is said that although the javadoc says requestCode is
not used, the real OS code consider the value specified there. Then, I
used the requestCodes to distinguish the PendingIntent starts.
Is it possible to get information from the API builders, what will be
the purpose of the requestCode parameter on PendingIntent creation in
the future? The reason is I want to be able to sure that my code won't
stuck at that time of API change.

info+farm
