Attributes: RegisterAttribute

Remarks

Launch an activity for which you would like a result when it finished. When this activity exits, your onActivityResult() method will be called with the given requestCode. Using a negative requestCode is the same as calling startActivity(Intent) (the activity is not launched as a sub-activity). Note that this method should only be used with Intent protocols that are defined to return a result. In other protocols (such as Intent.ACTION_MAIN or Intent.ACTION_VIEW), you may not get the result when you expect. For example, if the activity you are launching uses Intent.FLAG_ACTIVITY_NEW_TASK, it will not run in your task and thus you will immediately receive a cancel result. As a special case, if you call startActivityForResult() with a requestCode >= 0 during the initial onCreate(Bundle savedInstanceState)/onResume() of your activity, then your window will not be displayed until a result is returned back from the started activity. This is to avoid visible flickering when redirecting to another activity. This method throws ActivityNotFoundException if there was no Activity found to run the given Intent.
