Abstract: Systems, methods, routines and/or techniques for customizing native operating system views using web technologies in mobile devices are described. A messaging system may be used to allow and/or facilitate communication between two or more native views, for example, via one or more software development kits (SDKs). A method may include executing, in a first native operating system view, messaging code to communicate one or more messages from the first native operating system view to a second native operating system view. The method may include executing the software development kit code to receive and/or handle the one or more messages from the first native operating system view and route and/or transmit the one or more first messages to the second native operating system view. In some embodiments, the first native operating system view is a WebView and the second native operating system view is a VideoView.

Abstract: A method, apparatus and computer-readable storage medium for adapting alternative documents associated with content to be rendered in a mobile device is disclosed. A method, apparatus and computer-readable storage medium for adapting content, such as ads, based on presence or absence of certain mobile applications is disclosed. The mobile device performs receiving a group of contents together with condition code for each respective content. The mobile device checks a condition code, which includes examining the set of mobile applications contained in the mobile device, selecting and showing the content whose condition code specifying presence or absence of a set of mobile applications is met. A server computer is disclosed for serving a requested content based on checking a condition code. A client front-end is disclosed that enables specifying an ordered sequence of alternative documents or specifying conditions to be met in order to show respective content from a group.
