read lines of text file to string array - inputstream

Question

I need to write lines of text into a file and then read them line by line.
therefore I used these codes to write into a file:
String string = "Hello world55555555555!" + "\r\n";
FileOutputStream outputStream;
try {
outputStream = getActivity().openFileOutput(filename, Context.MODE_PRIVATE);
outputStream.write(string.getBytes());
outputStream.flush();
outputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
return true;
which it seems work properly. but when I am reading it get error! I am trying to read it by these codes:
FileInputStream inputStream = null;
BufferedReader reader;
String[] text = new String[0];
List < String > words = new ArrayList < String > ();
String line;
try {
inputStream = getActivity().openFileInput(filename);
reader = new BufferedReader(new InputStreamReader(inputStream));
while ((line = reader.readLine()) != null) {
words.add(line);
}
text = new String[words.size()];
text = words.toArray(text);
} catch (IOException e) {
//You'll need to add proper error handling here
}
tv.setText(text[0]);
Toast.makeText(getActivity(), text[1],
Toast.LENGTH_SHORT).show();
}
any comments! Please!

Thanks for your considerations, I update my read codes to:
FileInputStream inputStream = null;
BufferedReader reader;
StringBuilder[] total = new StringBuilder[]{};
String line;
try{
inputStream = new FileInputStream(filename);
reader = new BufferedReader(new InputStreamReader(inputStream));
int j =0;
while ((line = reader.readLine()) != null) {
total[j].append(line);
j++;
}
}
catch(IOException e){
//You'll need to add proper error handling here
}
tv.setText(total[0]);
Toast.makeText(getActivity(),total[1],
Toast.LENGTH_SHORT).show();
}
But I get errors yet and app shutdown:
