⟩ Tell me what is the difference between ChildBrowser and InAppBrowser in PhoneGap?
As the name suggests, Child Browser Plugin is a plugin and can be integrated in any phonegap application.
Whereas, InAppBrowser is a phonegap API that provides the ability to spawn a browser instance from a Cordova(2.3.0) application. The API is based on standard browser capability. In a nutshell, this has the same functionality as the ChildBrowser, and has events support as well.
