Reading file from assets directory throws FileNotFoundException

Question

I'm trying to read in a text file of a bunch of words that I want to use for a word game I am writing. This list is stored in the assets directory and is a txt file. But, whenever I attempt to open it, it throws an exception.

List<String>wordList = new ArrayList<String>();
    BufferedReader br = null;
    try {
        br = new BufferedReader(new InputStreamReader(getAssets().open("wordlist.txt"))); //throwing a FileNotFoundException?
        String word;
        while((word=br.readLine()) != null)
        wordList.add(word); //break txt file into different words, add to wordList
    }
        catch(IOException e) {
            e.printStackTrace();
        }
        finally {
            try {
                br.close(); //stop reading
            }
            catch(IOException ex) {
                ex.printStackTrace();
            }
        }
        String[]words = new String[wordList.size()];
        wordList.toArray(words); //make array of wordList

        for(int i=0;i<words.length; i++)
            Log.i("Brian", words[i]); //print out words in array
}

Here's the error log, in case that's any help:

Thanks everyone!

Answer 1

Check whether the file was properly packaged in the assets folder inside the .apk file. (It can be browsed as a zip file. Rename it if necessary to look inside.)

Answer 2

on Maven, the Assets folder needs to be inside projectName/ not inside projectName/src/main as suggested in other examples.
