Difference Between Pendingintent.send(...) And Activity.startintentsenderforresult(...)

There seem to be (at least) two ways to send Intents in Android: PendingIntent.send(...) Activity.startIntentSenderForResult(PendingIntent.getIntentSender(), ...) Other than the

Solution 1:

Seems like these two approaches are very different:

• The start...forResult(...) methods start an intent or sub-activity in a way that allows for a result to be returned to the activity that executed the start...forResult(...). The result will be passed back to the activity's onActivityResult(...) method.
• All other ways of launching intents or sub-activities (including PendingIntent.send(...)) act in a fire-and-forget-manner and don't allow for any results to be returned. The OnFinished handler is called as soon as the launch is sent, whether or not it takes a while to complete. The data passed into this handler, therefore, does not necessarily have anything to do with what you would otherwise receive via onActivityResult(...). In fact, in my case, the OnFinished handler is always called right away, before the dialog of the sub-activity even shows up, with a resultCode of Activity.RESULT_CANCELED.

What a mess...
