Activity events on startActivity

Is there any event triggered on an activity when I call

startActivity("activity_id", myIntent);

If the Activity exists already.

I pass a parameter to the activity via

i.putExtra("someID", someSerializableObject );  

and would like to call a method to refresh a WebView.

Right now, the call on startActivity brings the a开发者_C百科ctivity in the foreground but the webview does not display what i want.

Depending on the flags in your Intent and the settings in your manifest, your activity will be called with either onCreate() or onNewIntent().
