Basic Android WebView Application

This is an Android WebView application for Android version 1.6 or greater. This application attempts to load a URL using a userID and server_name. ## Deliverables ========= BEHAVIOR: 1. Start application 2. Check the persistent storage, such as "Shared Preferences", to determine if a userkey and server_name are stored (and have reasonable values). 2.1 If yes, then perform a loadUrl("http://<server_name>/folder/<userkey>"). The userkey and server_name are retrieved from the persistent storage referred to in step 2. 2.1.1 If this fails then go to 2.2 2.2 If no, then attempt to authenticate (which starts with a loadURL("[login to view URL])). 2.2.1 When PHP form is presented login into with a username/password. We have already written this form. Since we cannot perform a login from WebView and catch response at the same time this existing PHP script, which is needed for login, accepts username/password and returns the JSON object. 2.2.2 If the username/password match, the PHP code passes a JSON object to the Android using the syntax: echo json_encode($result); ...where a string similar to the following is echoed: {"userkey":"bbbbaf1ea0f505a249c988c71963","server_name":[[login to view URL]][1]} If the username/password fail go to 2.2 2.2.3 Use Android persistent storage, such as "Shared Preferences", to store the userkey and server_name as retrieved from the echoed userkey and server_name. 2.2.4 Perform a loadUrl("http://<server_name>/folder/<userkey>"). Example: loadUrl([[login to view URL]][2]); ================== NOTES: 1. I have the PHP code that performs steps 2.2.1 and 2.2.2. PHP code is NOT part of the delivery. ================== ALWAYS: 1. check network connectivity before calling a URL 2. check availability of domain name (e.g., can I ping it?) before performing a loadURL 3. show a webview progress bar when loading 4. show "connected" in title bar when connected 5. show "not connected" in the title bar when not connected 6. show "connecting&#8230;" in the title bar when attempting to connect 7. include a "LOGOUT" menu button that allows the user to clear the userkey and server_name persistent storage =========
