Description

Window's android back event handler is faulty or event not functioning at all. Compare the following code with version 6* of the SDK with version 5.5.1.GA where it works. Sample code: var win1 = Titanium.UI.createWindow({ backgroundColor : "white", }); // Add to the parent view. win1.add(aWebView); win1.addEventListener('androidback', function () { alert("Don't go!"); }); win1.open(); Expected behaviour: When back button clicked in Android, the application should remain open and the alert be shown. Actual behaviour: Application closes and the alert is never displayed.

Hello, I can verify the issue with the sample code below in SDK 6.0.1.GA, 6.0.0.GA, 5.5.1.GA with Android 6.0.1 device.

   var win1 = Titanium.UI.createWindow({
       backgroundColor : "white",
   });
   
   win1.addEventListener('androidback', function() {
       alert("Don't go!");
   });
   
   win1.open();

androidback event not fired in SDK 6.0.1.GA. This works fine for SDK 5.5.1.GA. Now, I have tried with "windows:back" instead of "androidback' http://docs.appcelerator.com/platform/latest/#!/api/Titanium.UI.Window-event-androidback too. Same result. I even tried it for tabgroup, androidback event not fired in SDK 6.0.1.GA, 6.0.0.GA. This works fine for SDK 5.5.1.GA.

   var win1 = Ti.UI.createWindow({
       backgroundColor: 'blue',
       title: 'Blue'
   });
   win1.add(Ti.UI.createLabel({text: 'I am a blue window.'}));
   
   var win2 = Ti.UI.createWindow({
       backgroundColor: 'red',
       title: 'Red'
   });
   win2.add(Ti.UI.createLabel({text: 'I am a red window.'}));
   
   var tab1 = Ti.UI.createTab({
       window: win1,
       title: 'Blue'
   }),
   tab2 = Ti.UI.createTab({
       window: win2,
       title: 'Red'
   }),
   tabGroup = Ti.UI.createTabGroup({
       tabs: [tab1, tab2]
   });
   tabGroup.open();
   
   tabGroup.addEventListener('androidback', function() {
       alert("Don't go!");
   });

To sum up, androidback event not fired on both window and tabgroup in SDK 6.0.1.GA, 6.0.0.GA. This works fine for SDK 5.5.1.GA.
