In the ACTION_CALL documentation, it states: "Note: there will be restrictions on which applications can initiate a call; most applications should use the ACTION_DIAL." So even if you can get past the NullPointerException, you may still not be able to place the call. Now, probably it will work, as there have been recent tutorials demonstrating that it works from an activity, but I could see where this might get locked down sometime in the future. > I am also wondering if there exists within the exposed Android API, a > way to hang up a call in an automated fashion.

You could putter through the source code to see how the in-call application handles it. Again, whatever technique it uses is probably not for public consumption, your mileage may vary, do not taunt Happy Fun Android, etc. > I'll be reconfiguring the program to see if I can get different > results - perhaps I missed something simple in the Manifest. However, > a NullPointerException really does merit some explanation. Well, hackbod took a guess, and her guesses are pretty damn good. Is whatever Context represented by initiateCall "real"? For example, if initiateCall is some Activity you instantiated yourself as part of this automated , that may not be fully-formed (i.e., gone through the normal lifecycle) and therefore may not be able to start other activities. I hate to be the bearer of bad tidings, since you read my book and all ;-), but I'm not terribly hopeful you'll be able to place a call, initiated by some remote application, automatically, without user intervention. Or, to put it another way, if it works, it'll scare the crap out of me, because there's all sorts of nasty things one can do with that technique. -- Mark Murphy (a Commons Guy) http://commonsware.com _The Busy Coder's Guide to Android Development_ Version 1.4 Published! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
