Please try to catch the FileNotFoundException in:

<pre><code>catch (FileNotFoundException e) {
 System.out.println("File not found");
}
</code></pre>

And check the console for File not found. 
If so the filename is not correct, the only other exception you might get is an I/O but that won't be the issue.

In the case of the function <code>openFileOutput</code>, the <code>FileNotFoundException</code> is thrown for multiple reason:

<ul>
<li>If the directory where the file is created doesn't exist</li>
<li>If the file can't be created because of some permission problem</li>
</ul>

In the <a href="http://developer.android.com/reference/android/content/Context.html#openFileOutput(java.lang.String,%20int)" rel="nofollow">documentation</a> it also states that the name of the file can not contain path separator so check if your path name follows this requirement.

Edit:

<pre><code>try {
 FileOutputStream gamFile = openFileOutput(fileName, Context.MODE_PRIVATE);
 gamFile.write(totItemsStr.getBytes());
}
catch(Exception e) {
 // Log your error
}
</code></pre>

wrap your code in try-catch block like this.., 

<pre><code>new Thread (new Runnable() {
 public void run() {
 try{
 // Write game data to a file
 String partStr = gameName.replace(" ", "_");
 String fileName = partStr + "_game.txt";

 FileOutputStream gamFile = openFileOutput(fileName, Context.MODE_PRIVATE);
 gamFile.write(totItemsStr.getBytes());

 }catch (Exception e){
 // exception found -&gt; do something
 e.printStacktrace();
 }

 }
}).start(); // end of thread
</code></pre>

it should fix your unhandled FileNotFoundException and 'gamFile' cannot be resolved problem

I have this code, just trying to create a new file:

<pre><code>// Write to file in thread
 new Thread (new Runnable() {
 public void run() {

 // Write game data to a file
 String partStr = gameName.replace(" ", "_");
 String fileName = partStr + "_game.txt";

 FileOutputStream gamFile = openFileOutput(fileName, Context.MODE_PRIVATE);


 gamFile.write(totItemsStr.getBytes());

 }
 }).start(); // end of thread
</code></pre>

...but I get a compile error on the openFileOutput command, saying 'Unhandled exception type FileNotFoundException'. 

If I put a try block around that to catch that exception, the error moves to the write command, saying 'gamFile' cannot be resolved.

Is the problem that I am trying to do this in a thread? Or is it the filename string wrong - should it be some object?

Any ideas gratefully received.

NOTE: 
1. I have tried a TRY block.
2. This error occurs at compilation, BEFORE the code is run (I cannot run it because this compilation error prevents a build).
