无法在存储根目录中创建文件？

Question

I have a simple app am trying to finish: //listing all of the SD Cards file names in a txt file.

And I've tried so many ways of at least creating the file in the root storage directory but with no luck ( not in the apps private files using "getFilesDir()" ) and one of those ways are shown in the code sample. And yes i used the proper permissions.

Any help would be so much appreciated.

String path = Environment.getExternalStorageDirectory().getAbsolutePath();
    File file = new File(path, "Something.txt");
    file.mkdirs();

    String[] array = file.list();

    try {

        FileOutputStream fos = new FileOutputStream(file, true);
        OutputStreamWriter osw = new OutputStreamWriter(fos);
        osw.write(String.valueOf(array));
        osw.close();

    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

Answer 1

If you are writting to external storage add this permisions to your manifest file:

<manifest ...>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
...
</manifest>

acording to this [Article.][1]

Answer 2

You need to call osw.close(); for the file to be created.

Answer 3

After digging and playing around a bit,

it turns out that i forgot to to call "fos.close()" and not just "osw.close()"

as well calling "file.createNewFile()" was mandatory , "mkdirs()" isn't working for some reason.

but thanks to everyone, all of your participation and effort were appreciated.
