Ionic/Cordova menubutton event not called

Question

I am trying to monitor the Menu Button on Android (4.4.2 - Samsung S3), but the Ionic event (nor the underlying Cordova event) is not firing:

$ionicPlatform.on("menubutton", function () {
  // do our stuff here (never gets called)
});

Has anyone been able to make this work? Running Ionic platform 1.0.0, and all other events are firing as expected.

Answer 1

The docs are missing a line.

document.addEventListener("deviceready", function() {
    ...
    navigator.app.overrideButton("menubutton", true);  // <-- Add this line
    document.addEventListener("menubutton", yourCallbackFunction, false);
    ...
}, false);
