Trying to get a file path to a public folder on android device and get its content

问题

I am looking to get the file path of a folder and then get its content. The folders are a public folder that you can access by just connecting the device into the computer. How do I go about getting a the file path to get access to these public folders and then get all its content?

So once I connect my computer to the device these are the folders I see and there is one that says "Folder to get items from" and I can't seem to figure what the file path is in order to get access to its content .

This is how I'm trying to get its content and Log them

    File fileOfEpubs = new File("/data/data/Folder of to get items from/");


    File[] dirEpub = fileOfEpubs.listFiles();

    if (dirEpub.length != 0){
        for (int i = 0; i < dirEpub.length; i++){
            String fileName = dirEpub[i].toString();
            Log.i("File", "File name = " + fileName);
        }
    }

回答1:

You appear to be looking at the root of external storage. Programmatically, you access that via Environment.getExternalStorageDirectory(). That requires either the READ_EXTERNAL_STORAGE or WRITE_EXTERNAL_STORAGE permission.

回答2:

You may need to escape the spaces in your string

File fileOfEpubs = new File("/data/data/Folder\ of\ to\ get\ items\ from/");
