Buffered Reader генерирует исключение FileNotFound при чтении FIS

/ 26 декабря 2018

В первом методе я создал файл в каталоге Applicatin, и я пытаюсь прочитать его с помощью BufferedReader, но по какой-то причине приложение продолжает генерировать исключение FileNotFound, и я понятия не имею, почему.

Writer output = null;
    File file = new File(getApplicationContext().getFilesDir(), "past");
    output = new BufferedWriter(new FileWriter(file, true));
    output.write(format_1 + "Overall positivity was " + sprog);
    output.close();

и вот код читателя 

public void past(View v) throws IOException {
    try(BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("past"),StandardCharsets.UTF_8))){

        String line;

        while ((line=br.readLine()) != null){
            System.out.println(line);
        }
    }
}

это то, что выдает отладчик
