As a user with Nuxeo Mobile installed in my Android device :

• On images, files or attachment from any apps, when I click on share I can see an entry "Add to Nuxeo" with Nuxeo Icon (I can see Nuxeo in allowed activity
• As a non authenticated user, when I click on "add to Nuxeo" icon in share options, I can see a Nuxeo screen with the text "Authenticate in Nuxeo app before using this extension" and a cancel button.
• As an authenticated user, when I click on "add to Nuxeo" icon in share options, I 'm redirected to nuxeo mobile app in the browse section:

• "import" top-right (blue), "cancel" button as a navbar
• listed folders and files from default personal space content
• A "Save here" button at the bottom-right (?...)
