like below fixes the issue so I started some Android programming with Java 7. I have Eclipse Juno (I think that's 4.2). , Your calling method inside onclick is wrong so try below way :-
code :
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    counter = 0;

    username = (EditText)findViewById(R.id.getEmail);
    password = (EditText)findViewById(R.id.getPassword);        

    login.setOnClickListener(new View.OnClickListener() {       
        public void onClick (View v) {
            if(username.getText().toString().equals("admin") && password.getText().toString().equals("admin")){
                success = "Successful";
                counter = 0;
               sendMessage(v);
            } else {
                    counter++;
                    login.setText("Unsuccessful. Try again. " + 3-counter + " tries left.");
            }   
        }   
    });

 public void sendMessage (View view){
                        Intent intent = new Intent("com.example.linked1n.SCREENAFTLOG");
                        startActivity(intent);
                    }

Any of those help
What would you recommend for someone who has a background in python and C++?

To fix the issue you can do You have some stray text (endl/) at the end of the second last line, which is causing a parsing error.
You also appear to have typed return o; (the letter "o") - as you don't have a variable called o this will also cause an error. I suspect you meant return 0; instead.

I hope this helps you . I am trying to get more proficient with Java. I am making a simple card game to test my basic skills. I have come across a problem in my Deck class. The for-loops are not creating new card objects in my arraylist even though they should. When I call getTotalCards the size of the arraylist is always 0. Any ideas of what I am doing wrong? , The conditions in for loop are wrong. should be i<=4 and j<=13
