Write an Android application

Technologies Server: .NET Framework 4.5.1 and MySQL Client: Ionic 2 w/ Angular Client/Server Communication: REST Create an client app (ionic) with 2 screens (minimal details that will be exchanged with already drawn screens). We're looking for the functions only. 1st screen: [label]User: [/label] [input user] [label]Pass: [/label] [input pwd] [button]Enter[/button] [button]Clear[/button] 2nd screen: [button]Log Out[/button] [input name=var] [label txt1][/label] [button]Server[/button] On 1st screen: On clicking the button "Enter" the app must check if the inputs aren't blank and authenticate with the server through the OAuth2 protocol. On clicking the button "Clear" the app must clear the inputs. On 2nd screen: On clicking button "Log Out" the app must end the connection with the server through any OAuth process. On clicking button "Server" the app must call the service "testserver" sending the content of the input "var" as a parameter. The returned string should be shown in the label "txt1". Server implementation: - Authorization/Authentication service of OAuth2, let the SQL command to a MySQL DB be in the comments and make the service accept any user-pass combination instead. - "testserver" service that receives a string and returns the system time as a string (obtained from the machine's clock).
