Thank you for your answers. But i am not sure i can do my task just with an ObjectChooser. And i need your advices for the strategy i should adopt : <ul><li>I want my application to "save a graph" by writing the coordinates in a text file => i am conviced that for this tasks, i should use the folder data of the activity</li> <li>i want my application to "load a graph" from a previously recorded graph </li><li>but i also want the users to share other graphs each others : more precisely, for users who don't have internet access (or for later systems restores, maybe after a crash, for example) to be able to import files from a usb key</li> </ul>So, what is the best strategy in order to do these tasks and remain conform to Sugar best practices ?
