Phonegap navigator.notifications does nothing

Starting to play with phonegap for the android and am not able to get anythi开发者_StackOverflow中文版ng in the navigator.notifications to work (actually looks like navigator.<anything> is not working). In my JS I have tried

navigator.notification.vibrate(1000);
navigator.notification.vibrate();
navigator.notification.alert("one", "two", "three");
navigator.notification.beep(1);

none of them do anything, the app just continues right on past them like nothing ever happened. If I alert(navigator) I get [object object] but alert(navigator.notification) gives null.

PhoneGap for Android supports all three notification methods you mentioned. For me it looks like you try to run them before PhoneGap is ready (so before navigator.notification object is initialized). Make sure your code is not executed before PhoneGap notify deviceready event. Just for test you can try to run a code like this:

document.addEventListener("deviceready", function(){
   navigator.notification.vibrate(1000);
   navigator.notification.alert("Hello");
   navigator.notification.beep(1);   
}, false);

Please also notice that in your example there is a mistake in alert method invocation. The second parameter is a callback (executed after user press/taps button on alert), so you shouldn't pass a string there.
