How could Robotium enter a newline character inside a multiline EditText view?

[David Huang]

I have a multiline EditText view in the app.  I would like to enter multiline text in it with Robotium.  However, I tried the following three ways, none of them works for me:

  1.  solo.enterText(editText, "ab\nab");

  2.  solo.enterText(editText, "ab");
