Hi, recently, i have got sandbox access for AEM - Mobile, i am not able to find any major difference between apps -> phonegap and AEM - Mobile (new system) aka DPS. Please let me know if you have any article link to explain the difference? already gone through the quick start guide for AEM - Mobile but did not get cleared my doubts.
AEM Mobile handles content distribution, CMS connections, out-of-the-box navigation and a bunch of other things. Comparing to phonegap is like comparing apples to the water, earth and air that goes into the making of an apple; with phonegap, the sky's the limit, but you gotta build all of it. With AEM Mobile, there's pretty significantly less flexibility, but you have to do significantly less of the basics yourself.
For both PhoneGap and AEM Mobile, you can use Apache Cordova plug-ins to access native device APIs such as GPS, camera, contacts, and accelerometer. Both PhoneGap and AEM Mobile work well with AEM authoring.
