Javaからシェルコマンドのリアルタイム出力を読み取るにはどうすればよいですか？

これは私がこれまでに持っているものですが、コマンドが実行された後に出力されます：

try {
    proc = Runtime.getRuntime().exec("du -d 1 /sdcard/");

    InputStream inputStream = proc.getInputStream();
    InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
    BufferedReader bufferedReader = new BufferedReader(inputStreamReader);

    while ((line = bufferedReader.readLine()) != null) {
        publishProgress(i);
        i++;
        System.out.println(line); // it prints all at once after command has been executed.
    }
}
catch (IOException e) {
    Log.e("du","error "+e.getMessage());
}

これを試して：

try {
 proc = Runtime.getRuntime().exec("du -d 1 /sdcard/");

 InputStream inputStream = proc.getInputStream();
 InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
 BufferedReader bufferedReader = new BufferedReader(inputStreamReader);

 while ((line = bufferedReader.readLine()) != null) {
    System.out.println(line); // it prints all at once after command has been executed.
 }
 proc.waitFor();
}
catch (IOException e) {
 Log.e("du","error "+e.getMessage());
}
