Apps Error trying to read a text file and put it into xml textview

[blankwall]

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.help);
InputStream iFile = getResources().openRawResource(R.raw.quizhelp);
TextView helpText = (TextView) findViewById(R.id.TextView_HelpText);
String strFile = inputStreamToString(iFile);
helpText.setText(strFile);
}
}
There is my code. The problem is with the inputStreamToString(iFile).It says that it is undefined. Im working my way through an android book and that is exactlly out of the book. I have looked around and tried a few different ways but cant seem to make it open the quizhelp file and display it in the TextView_QuizHelp. Any help is much appreciated.

If the book you use is "unlocking Android" maybe you can see this page

Manning Forums: StringUtils.inputStr ...

Where is stated that the inputStreamToString function is not present in the Android sdk.
The same page contains a link to the code missing from the book example.
