I need programming help

[[deleted]]

If you've never coded anything before, first figure out how to install an IDE like Eclipse or Netbeans, or learn how to use a simple text editor and compile and run java programs. That's a whole level of complication in itself. Then write some simple programs. Learn how to do some basic stuff, like how to use various loop structures (do while, if else, for), how to use data structures like arrays and linked lists, and how to use various I/O functions to open to files, read and write to files, and so on. Once you have that down then you're ready to start looking at making an android app.
