I have the following code:

File folder = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS) + "/Inventario");
    if (!folder.exists()) {
        if (folder.mkdirs()) {
            Toast.makeText(this, "Carpeta Creada", Toast.LENGTH_SHORT).show();
        }

    }

the application generates the folder and is visible from the 'device' browser, but when I try to access from the computer it does not show me the folder. It is only visible after restarting the 'device'. the android version is 6.0

If you have files or folders created in the external storage directory, these can be displayed without any problem using a file browser or the same File Explorer of Android Studio .

Here the problem is that although you can view the files using File Explorer (File Explorer) , you can not programmatically read files or directories if you do not define the permission of WRITE_EXTERNAL_STORAGE , by defining this permission this implicit permission is READ_EXTERNAL_STORAGE .

For versions of the Android operating system prior to 6.0, it is sufficient to define the permission within AndroidManifest.xml

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

For later versions of Android 6.0, it is also important to require the permissions manually.

In this question you can see a method to require permission:

Error when displaying the external file directory in an AlertDialog in android 6.0 (READ_EXTERNAL_STORAGE / WRITE_EXTERNAL_STORAGE)

Important to mention that in some versions of the Android operating system there is no "Documents" directory to which Environment.DIRECTORY_DOCUMENTS relates, therefore it must first be created.

File folder = new File(Environment.getExternalStorageDirectory() + "/Documents");
