Menu
I am using PhoneGap 1.5.0, jQuery 1.7.1 and jQuery mobile 1.0.1 and trying to override the backbutton in Android as stated here or here.
document.addEventListener("deviceready", onDeviceReady, false);
// PhoneGap loaded
function onDeviceReady() {
console.log("PhoneGap Ready!");
// waiting for button
document.addEventListener("backbutton", handleBackButton, false);
}
// handle the back button
function handleBackButton() {
console.log("Back Button Pressed!");
navigator.app.exitApp();
}
But it only works on the first page of my app. After changing to a different page the backbutton does nothing at all. The app consists of a tabview like this:
<body>
<div data-role="page" id="pilotTab">
<div data-role="header">
<h1>Pilot</h1>
</div>
<div data-role="content" id="pilotContent">
content be here ;)
</div>
<div data-role="footer" data-position="fixed">
<div data-role="navbar">
<ul>
<li><a href="pilotTab.html" data-transition="none">Lotse</a>
</li>
<li><a href="bookingTab.html" data-transition="none">Verkehr</a>
</li>
<li><a href="mainListTab.html" data-transition="none">Bört</a>
</li>
</ul>
</div>
<!-- /navbar -->
</div>
<!-- /footer -->
</div>
Is it a stupid mistake or is there something special I have to consider to make it work properly? Thanks in advance.

I gone through the new Phonegap source code and did following changes to make the backbutton work.
Html test code
<script type="text/javascript">
$("#home").click(function(){
$.mobile.changePage("home.html");
});
document.addEventListener("deviceready", onDeviceReady, false);
document.addEventListener("backbutton", handleBackButton, false);
function onDeviceReady() {
console.log("PhoneGap Ready!");
}
function handleBackButton() {
console.log("Back Button Pressed!");
navigator.app.exitApp();
}
</script>
Put the following code in the else block of document.addEventListener in cordova-1.5.0.js after line-no 507
if (e === 'backbutton') {
var exec = require('cordova/exec')
exec(null, null, "App", "overrideBackbutton", [true]);
}
Put following code in fireDocumentEvent method of cordova definition in cordova-1.5.0.js after line-no 592
if(type == "backbutton"){
var e = document.createEvent('Events');
e.initEvent(type);
if (data) {
for (var i in data) {
e[i] = data[i];
}
}
document.dispatchEvent(e);
return;
}
I have put the whole cordova-1.5.0.js in this gist with updated code https://gist.github.com/2020325
Though it is working for me but it still may need some changes to work in all the possible scenarios.
Put following code in fireDocumentEvent method of cordova definition in cordova-1.5.0.js after line-no 592
if(type == "backbutton" || type == "menubutton" || type == "searchbutton"){
var e = document.createEvent('Events');
e.initEvent(type);
if (data) {
for (var i in data) {
e[i] = data[i];
}
}
document.dispatchEvent(e);
return;
}
Bryce Curtis is suggesting on that page to just change the line :
channel.onNativeReady.subscribe(_self.boot);
to :
channel.onNativeReady.subscribeOnce(_self.boot);
at the end of the file.
That seems to do the trick for me and fixed the backbutton AND the menubutton and searchbutton !
