Android Cannot get access to data folder

[technew]

After you get storage permission, you can use following method to get root path.

    public static String getRootFilesDirPath() {
        if (Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState())) {
            File[] files = ContextCompat.getExternalFilesDirs(getContext().getApplicationContext(),null);
            return files[0].getAbsolutePath();
        } else {
            return getContext().getFilesDir().getAbsolutePath();
        }
    }
