android: EACCS permission denied when using context.getExternalFilesDir

Question

Im basically trying to download a file from an url.So i decided to store in my app file.So I used getExternalFilesDir, so that i don't require any permission pop up as per these links:

Do I need runtime permission check to write into getExternalFilesDir() path in marshmallow?

getExternalFilesDir permissions

The Death of External Storage: The End of the Saga(?)

However, it works on android 8.0, but on my Letv Le 1s Marshmellow device without storage permission, it doesn't work!

Below is my code:

        if(TextUtils.isEmpty(urlString))
            return;
        URL u = new URL(urlString);
        is = u.openStream();
        dis = new DataInputStream(is);
        byte[] buffer = new byte[1024];
        int length;
        File storageDir = new File(getApplicationContext().getExternalFilesDir(Environment.DIRECTORY_MOVIES).toString(), "downloads/");
        String fileNameFromUrl = urlString.substring(urlString.lastIndexOf("/")+1,urlString.length());
        String ext = urlString.substring(urlString.lastIndexOf(".") + 1, urlString.length());
        storageDir.mkdirs(); // make sure you call mkdirs() and not mkdir()
        File downloadPath = new File(storageDir + File.separator +  fileNameFromUrl);
        if(downloadPath.exists()){
            downloadPath.delete();
        }
        downloadPath.createNewFile();

downloadPath is /storage/emulated/0/Android/data/com.example/files/Movies/downloads/file.mp4

This line downloadPath.createNewFile(), throws java.io.IOException: open failed: EACCES(Permission denied)

My idea is to use the application's directory for reading and writing files for in-app uses and not to ask for storage permissions.So I used context.getExternalFilesDir.

I have explored many SOF links as mentioned above, but it didn't help me solve the issue!

@blackapps: I have checked all the times: storageDIrs always exists: moreover i give storageDir.mkdirs() also — adi, Mar 16 '20 at 09:30
@FahadAlotaibi May i know the difference between getFilesDir() and getExternalFilesdir()? — adi, Mar 16 '20 at 09:34

`over i give storageDir.mkdirs() also – `. You are not checking the return value of mkdirs(). Check it! And dont call mkdirs if the directory already exists. — blackapps, Mar 16 '20 at 11:58
It is pretty strange that you can create directories like 'Movies/downloads' but not a file in it. — blackapps, Mar 16 '20 at 11:59
`downloadPath.delete();`. Check the return value and handle accordingly. — blackapps, Mar 16 '20 at 12:04
storageDir.mkdirs() returns me false, when i dont give storage permission explicitly, but it gives me true when i give the permission..but in my android 8.0 device, it works without any explicit permission given!! — adi, Mar 16 '20 at 12:29
