Ebay function on Android. 2 activites with Ebay api

phase 1 - Create 'products' activity with Download icon/button on top. Create 'settings' activity with fields for Ebay User/Pass. Clicking a 'Go' button on the SettingsActivity (under the user/pass fields) will open a webview to get the token and allow 3rd party access to LegionMS for that customers account. This will save the appropriate keys to this settings page (non editable). After the keys are created the user can than go to the products activity and select the 'download' icon, when clicked, it will call Ebay API to import and list all products. You will need to let me know th full range of info, so I can see what fields we should show. The info is saved to Sqllite on the device phase 2- On the list of products, include a '+' button. This button would start an activity to create a new product. Inputting information to save to the list. Each product in this list or table view should be selectable. When clicked, a details slideup animation will occur that will provide all data and image of the product. If its a new product, that data can be edited or added and then 'posted' to ebay, so it can be sold.
