Code posted in forums doesn't seem to pass...

If anyone is out there, the code posted above is NOT working for me. I am getting this error:

./FileUtilities.java:28: error: cannot find symbol if (fileToWrite.exists() == false) { copyResult = copyFile(in, out); } ^ symbol: variable fileToWrite location: class FileUtilities 1 error

Posting my code below. Thanks.

FileUtilities.java
import java.io.InputStream;
import java.io.FileNotFoundException;
import java.io.IOException;

public class FileUtilities {

  public static boolean copyResult;

  public static void saveAssetImage(Context context, String assetName) {
    File fileToWrite = new File(context.getFilesDir(), assetName);
    AssetManager assetManager = context.getAssets();

    try {
      InputStream in = assetManager.open(assetName);
      FileOutputStream out = new FileOutputStream(fileToWrite);
      copyResult = copyFile(in, out);
    } catch(FileNotFoundException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    }
  }

  private static boolean copyFile(InputStream in, FileOutputStream out) {
    // Copy magic intentionally omitted
     byte[] buffer = new byte[1024];
        int read;
    if (fileToWrite.exists() == false) { copyResult = copyFile(in, out); }

  }
}

I would suggest passing fileToWrite through the method call. The method CopyFile doesn't know what to do with that variable since it was not declared in that method.
