I can't write to /mnt/sdcard2 in Android

Question

Now I'm making some version of File Manager in Andoid. My permission:

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

When I write new file to /mnt/sdcard (External Stroage) everything is allright. But When i write new file to /mnt/sdcard2 (internal storage) I get IOException like open failed: EACCES (Permission denied) My full code:

try {
            File existingFile = new File(path);
            File newFile = new File(newPath);
            if (!newFile.exists()) {
                if (!isFolder)
                {
                    newFile.createNewFile();
                }

            } 

            if (isFolder) {
                FileUtils.copyDirectory(existingFile, newFile);
            }
            else
            {
                FileUtils.copyFile(existingFile, newFile);
            }

        } catch (IOException e) {
            result = 1;
        }

When i test my application I use real device. My Path is like '/mnt/sdcard/Music/blabla' and so on

`/mnt/sdcard2` exists and I worked with this folder. It is internal storage for my device. I can copy files from `/mnt/sdcard2` to `/mnt/sdcard`. — НеДоПрограммист, Mar 06 '17 at 10:54
`if (!newFile.exists()) { if (!isFolder) { newFile.createNewFile(); } } `. You better remove all that code as it should not be needed as copyFile() should create the file. Moreover we cannot see how you initialize `isFolder`. — greenapps, Mar 06 '17 at 12:35

My Path is like '/mnt/sdcard/Music/blabla'

Do not use hardcoded paths as these may (and will) differ depending on device model or can even OS version. You got methods in Environment class to get you root folder of external storage and you should use it like getExternalStorageDirectory()

EDIT

. I need to get folder that contents folder like Music, DCIM, Download, but in Inner Storage of Smartphone

You cannot have "private" DCIM, Downloads really if you want to use system features like DownloadManager or external Camera app, because these apps will simply not be able to write to your private storage. So you either download/take photo yourself - then you can save the file whenever you want, or you use what is it now available, with all the pros and cons.

Name "external"/"internal" is a bit misleading nowadays, so do not take it too literally.

**getExternalStorageDirectory()** returns me ExternalStorage. How can I get **Internal storage**? – НеДоПрограммист Mar 06 '17 at 10:52
you asked about SD card. This used to be **external** storage. See [Context](https://developer.android.com/reference/android/content/Context.html) methods for internal ones – Marcin Orlowski Mar 06 '17 at 10:54
`How can I get Internal storage?`. getFilesDir(). – greenapps Mar 06 '17 at 12:06
So.. . `getFilesDir()` gives me my application folder like data/data/myApplication). I need to get folder that contents folder like Music, DCIM, Download, but in Inner Storage of Smartphone.

And I want to work with Internal storage, but what is absolute path for this? – НеДоПрограммист Mar 06 '17 at 12:27
`I need to get folder that contents folder like Music, DCIM, Download, `. Well then use getExternalStorageDirectory() or getExternalPublicDirectory(Environment.DIRECTORY_DCIM). – greenapps Mar 06 '17 at 12:34
