问题 I would like send an Intent to start an Activity. I would like to be able to modify that Intent. Then, when the activity is destroyed and recreated, I would like those modifications to still be present when I call getIntent() .

问题 Is it possible to to put an object of type Object into an intent as a Extra? I have a variable of type object and won't know until it is assigned a value as to what the object datatype is.

问题 I have a small application which can be used to set reminders for future events. The app uses an AlarmManager to set the time for when the user should be reminded. When the alarm goes off, a BroadcastReceiver registers this and in turn starts a service to notify the user via a toast and a notification in the status bar. In order to display the correct information in the notification and toast, some extra information is passed along with the intent. The first time a reminder is registered, the
