mkdir return false in android?

Question

This is my code

String DATA_PATH="/mnt/sdcard/";
        String[] paths = new String[] { DATA_PATH, DATA_PATH + "tessdata/" };
        for (String path : paths) {
            File dir = new File(path);
            if (!dir.exists()) {
                if (!dir.mkdirs()) {
                    Log.v("", "ERROR: Creation of directory " + path + " on sdcard failed");        
                } else {

                    Log.v("", "Created directory " + path + " on sdcard");
                }
            }

        }

I've tried using Environment.getExternalDirectory() but it still return false. The most confusing thing is it always said "ERROR: Creation of directory mounted on sdcard failed" on the logcat. How can the path changed into mounted? Can someone please give me a solution?

I don't want to sound stupid...but, have you tried restarting the device? Happened to me once and it was just a temporary issue — Alessandro Roaro, May 27 '15 at 12:26

if the mobile is connected to the system then we are not able to create folders so remove it and run the application

Why are you using mkdirs in the first place ? You should just do:

File file = new File(Environment.getExternalStorageDirectory(), "tessdata");
if (!file.exists()) file.mkdir();

Also, make sure you have the WRITE_EXTERNAL_STORAGE permission in the manifest.
