Correct. myPhoneTestActivity isn't created by the Android framework. It may be easier to think of Activity as being a plug-in to Android more so than a "program" in the traditional sense. Most plug-in frameworks don't give you fully-working plugins just by instantiating them. Instead, the plugins need to be wired into the overall system, code that frequently is done by whoever is launching the plugin itself, outside the bounds of the plugin's own constructors or callbacks. > I'm attempting to launch this new Activity with the ACTION_CALL Intent > and Android does not ~appear~ anyway, to know what to do with it. If > that theory is true, then no wonder the Activity is crashing... I've only tried ACTION_DIAL recently.
