1. AEM Mobile applications: Normal web pages integrate with Adobe Analytics, using Java script. But how would a mobile app integrate with Adobe Analytics? - it is same as using normal application. when you build the application, the javascrit is associated with it.
Even in cloud, it needs to send the data somehow to Adobe Analytics right?
3. What exactly is the difference between AEM Mobile applications & Mobile Apps built with Phonegap? Like one is native and the other is hybrid? - AEM Mobile is a cloud based application. It has set of plugins built in. You cannot add a custom plugin. But when using phonegap, its a hybrid application, you can add your custom plugins.
I heard AEM mobile will also soon have the ability to add custom plugins.
4. Which one should be used when? - If you're ok with plugins that are built in on AEM Mobile, you can use that.. please note that it doesn't require much IT efforts to create Mobile app using AEM Mobile. Where as using phone, you need AEM + Angular JS skills.
5. How will mobile apps built either way Integrate with all other AMC Products (forward & backward)? - I'm exactly not sure.. if AEM Mobile has integration with all the AMC products.. but using phonegap, it is a normal integration.
