title: How to use Android restricted API methods ¿reflection?
body: <p>I'm developing an app that has system privileges and I want to use the intallPackage() and deletePackage() methods, which aren't visible in the regular API. I have no idea about how to use reflection to make these methods available. Does someone knows how can I access this methods from code? What are the steps to make them available on Android SDK? Any tutorials about it?</p>
