Android app development

When the phone is rebooted, the app should start automatically, then if this API call was last made more than 14 days ago it should make an API call, and then it should exit (ie. this API call should only be made at most once every 14 days). If the API call was made and returned a specific value then the app should issue a notification asking the user to update the app

When run for the first time, it displays some simple intro messages which user can swipe through or ignore

Thereafter the entire screen (except for the menu) is filled with a WebView to a specified URL

If there is no internet connection, the app should say "This app requires an internet connection" plus "Exit app" and "Retry" buttons/links, plus have a link to WiFi-Settings if possible

WebView must have JavaScript and cookies enabled, changing the orientation of the device should be handled gracefully without reloading the page, pulling down should not reload the page

Menu options are:
My Entries Browse/Search
Settings
Help
Terms

Possibly easiest to implement this as "Browse Search" and "My Entries" tabs along with a vertical ellipsis for a menu for the other 3 items?

All except "Settings" are a WebView to different URLs

The "Back" button should exit the app. However it should prompt them to confirm they want to exit the app unless they have previously ticked the "Don't ask me this again" checkbox or have turned off this option in "Settings"

When the WebView has a form/link to the same page it should be loaded into the WebView (this is because the WebView will sometimes containa a form posting to itself)

When the WebView has a link to another page on "www.luckycheckout.com" it will open the page in their default browser, without asking them to confirm this action

When the WebView has a link to any other page, the link will be opened in their default browser; however it should prompt them to confirm they are leaving the app unless they have previously ticked the "Don't ask me this again" checkbox or have turned off this option in "Settings" ... nb: the prompt message will get the retailer's name from the query string of the URL

Settings will initially have 3 options: 1) Toggle ON/OFF = Warn me when I'm about to leave the app to visit a retailer's website , 2) RADIO = Back Button ... [N] Exit the app , [P] Prompt me to exit the app , [I] Ignore , and 3) BUTTON/Link/Toggle ON/OFF = Logout

If the user selects the "Logout" option, they should confirm their choice then it will load a URL in the background (or can it delete a cookie? if so that is easier) then reload the "Browse/Search" WebView
