What is the substitute for WL.App.close?

问题

WL.App.close is deprecated. I know that this is not supported for iOS. But why is it deprecated for Android as well? At the moment, it is still functioning fine, even on 6.2, but since it is deprecated, what is the alternative/substitute for this?

回答1:

In Android as well, this is not the recommended approach. You should let the user quit the app, and this is done by manually bringing up the "applications view" and swiping the app in order to quit it.

Can be corroborated by these answers by Googlers:

Additionally, there are these approaches:

• Close application and launch home screen on Android
• https://groups.google.com/forum/#!topic/android-developers/Y96KnN_6RqM

You could write a Cordova plug-in that will force-quit the app and trigger it by overriding whatever you'd like (like the Back button), or create a dedicated Quit button, etc.

In MobileFirst 7.0, this method seems to be deprecated in both iOS and Android, but when I call this "deprecated" method in Android, it really works.

I think overriding Android's back button might be a best practice in Android webapp as back button may cause strange page navigating issues (if you use UI frameworks like JQM). This is what I done in WL's main.js.

WL.App.overrideBackButton(backFunc);
function backFunc(){
    WL.SimpleDialog.show(
        "Alert", 
        "Sure to quit the app ?", 
        [ {text : 'Cancel', handler: function() {
        }},
        {text : 'Yes', handler: function() {
            if(WL.Client.getEnvironment() == WL.Environment.ANDROID) {
                WL.App.close();
            }
        }}]
    );
}
