Reading InputStream to Arraylist

I have to read a dict.txt file which contains one string for line and add these to an arraylist.

I tried this:

public ArrayList<String> myDict = new ArrayList<String>();

InputStream is = (getResources().openRawResource(R.raw.dict));
BufferedReader r = new BufferedReader(new InputStreamReader(is));
try {
    while (r.readLine() != null) {
        myDict.add(r.readLine());
    }  
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

but something wrong...

You are iterating twice in each loop

String line;
while ((line=r.readLine()) != null) {
    myDict.add(line);
}

Using Apache IOUtils:

List<String> lines = IOUtils.readLines(inputStream, "UTF-8");
