A singleTop activity won't be re-created in this situation. You can use "adb shell dumpsys activity" to look at what is going on with the activity stack, and look at the log to see what messages are printed.
That said, I *strongly* recommend you to not use singleTop for an activity that is intended to be launched by other applications like this. What is required for your activity to actually get all of the UI flows right in such a situations is significant. This is just not how the framework is intended to be used. The other application is performing a "share" as part of its UI flow; you should have a new activity instance running on the other application's task taking care of its share operation rather than dragging our application on top.
