DataManager as the only point of interaction with the data layer, making this architecture test-friendly. Help classes and DataManager can be easily simulated. What problems do we have? For large and complex projects, DataManager can become very bloated and difficult to maintain. Although the view layer components such as activity and fragment become lighter, they allow a lot of logic to be handled, such as managing Rxjava subscriptions, parsing errors, and so on. Integra

Ionic Framework IntroductionIonic is a angularjs-based, user-interface framework that uses HTML5 to build hybrid mobile apps, claiming to be "a combination of local and HTML5."

This is a set of scripts that can help analysts analyze the security of the app and develop it in the Perl language. Because it's just a few scripts, it may not be as smart to use, no GUI interface, no "elegant" analysis results. So basically, it's a script like "aapt-enhanced". With the added ability to analyze Android and analyze iphone apps, there are some useful words. Project address [Googlecode] https
