How can I pass data to a single task activity after the first time it loads

Question

I have an Activity that is a single task so I guess on create only gets called once. I want to pass some parameters from another activity. using Intent, i am putting extras but when I read them in the single activities onResume, the data is not there.

I need a way to pass data to a single task activity or restart it.

edit

To clarify. The problem is my activity uses Single Task as a launch mode in the manifest. I think this means oncreate only gets called once which is why i am trying to get the parameters in onResume.

When I resume my single task activit, I am unable to get any params added to the intent in the previousd activity because it does not start it but simply resume it

Answer 1

Use onNewIntent() with single-instance Activity. Calling getIntent() in onResume() for a single-instance Activity will return the Intent that originally started the Activity, not the Intent that the Activity just received. To ensure that getIntent() always returns the last-received Intent in a single-instance Activity, use setIntent() to store the last-received Intent.

This is documented in the reference documentation for onNewIntent()

Answer 2

if you are trying to pass data to an activity that was started with single task and the activity is currently up then you need to override onNewIntent when a new intent comes into that activity this is where it goes
