Implement ActionBar with Drawer to existing app

I already have a working mobile application for Android that is in the market and I would like someone to implement the design guideline of a Drawer with ActionBar on the whole application. Right now the application is working with the library SlideMenu with a custom view as an ActionBar and everything works good, but we would like to have the ActionBar always on top with the right "menu" icon or "back" button depending on the current navigation level. Exactly as the Gmail application for example. The ActionBar should have a custom background to match the design of the whole application. The application is quite huge as it have different sections. But once the main ActionBar is placed with the right Drawer it would be quite easy to complete the project. I may not need to complete the whole screens as I can complete the remaining screens if something should be changed. The application must work on API Level 4 and above. I already tried to make the ActionBar stay on place, but need to: - Apply the right theme with the background image - Show the menu or back icon depending on current navigation level - Detect the "menu or back" button in order to show or hide the slidemenu - Check if the deeper navigation level is compatible with the ActionBar - Explain me how to add menu items if needed - Show hide the menu key depending if the Slidemenu is open or not The update for this should be done for this Friday or Monday in the worst case. I will provide as much help as I can to accomplish this. I will require high confidentiality for this project as I will provide the source code. Possible a NDA sign in.
