I know many programming languages e.g. Delphi, Php, Visual Basic etc. but not Java.
I want to start developing Android applications that complete my solutions for Windows.
For example I have a storage management software that runs on Windows and the user would use the Android software to go to the store and edit / insert the numbers of the items.
To make it short I need directions (where to start, what to download, what books to buy,where to find examples etc.) to make Android applications that:
-have a visual interface (buttons, checkboxes, editboxes etc.)
-can connect to a MySql database through an Ip address (either using Internet connection or Wifi connection) and can execute queries, post data to server
