Translate Issue

So completed the translate program and when i run i get a force close when i try to input i check Logcat and this is what it found:

To debug this I’d print out the value of several of the variables in the getLang() method:

      String result = spinner.getSelectedItem().toString();
      Log.d("Translate", "item = " + spinner.getSelectedItem()
         + " , " + result = " + result);
      int lparen = result.indexOf('(');
      int rparen = result.indexOf(')');
      Log.d("lparen = " + lparen + " , rparen = " + rparen);
      result = result.substring(lparen + 1, rparen);

You may need to add an “import android.util.Log;” in the import block near the top of the file. Alternatively, if you’re comfortable in the debugger just set a breakpoint at the beginning of getLang() and step through it, looking at those variable values.

Either the selected item isn’t what it’s supposed to be, or the string value of that item isn’t what it’s supposed to be. If the former, check that the setSelection() calls in setAdapters() are done correctly. If the latter, check the languages array in res/values/arrays.xml to make sure they all are formatted like this:

      <item>English (en)</item>

In that one, for example, the “en” is the language code that getLang() is trying to extract.

Hi! First of all I want to thank for a great book! Second… I have a problem…
I tried to do the Tranlate program but keep getting this error, I`ve even copied all code from the book’s website.

It requires an active Internet data connection, with no firewalls in between you and the google server. Try entering this address in the web browser on your phone:

http://ajax.googleapis.com/nonesuch

If you get an error that says “The URL /nonesuch was not found on this server”, then your connection is working. If you get a different error, like a host not found error, then there’s something wrong with your Internet data connection.
