Set construction project JRE input path to 'Javase-1.7'

Question

I am trying to make a connection to Mysql database, but when I use PreparedStatement, eclipse returns: Definir projeto de construção JRE entrada caminho para 'JavaSE-1.7 Yes, I changed the compiler version to 1.7, but only works with Android 1.5 and 1.6 right? How can I connect my database? This is my real method to connect:

private ArrayList<String> sql = new ArrayList<String>();
private Connection con;
  public String getUsuario(String...parametros) throws SQLException {
            sql.add("SELECT "+parametros[1]+"FROM users WHERE `usuario_id` = "+parametros[0]+";");
               for (String string : sql) {
                try (PreparedStatement stm = con.prepareStatement(string);
                        ResultSet rs = stm.executeQuery()) {
                        while(rs.next()) {
                            System.out.println(rs.getString("usuario_senha"));
                        }
                    }
            }
            return "";
        }

Your problem isn’t the PreparedStatementbecause it exists in Java 1.6.

The problem is in the block try.
The form you are using only exists in Java 1.7.

You need to use the traditional block shape try/catch

try{
    PreparedStatement stm = con.prepareStatement(string);
} catch(SQLException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
