Answer 1

Try this simple snippet

    public static String readableFileSize() {
    long availableSpace = -1L;
    StatFs stat = new StatFs(Environment.getExternalStorageDirectory().getPath());
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN_MR2)
        availableSpace = (long) stat.getBlockSizeLong() * (long) stat.getAvailableBlocksLong();
    else
        availableSpace = (long) stat.getAvailableBlocks() * (long) stat.getBlockSize();

    if(availableSpace <= 0) return "0";
    final String[] units = new String[] { "B", "kB", "MB", "GB", "TB" };
    int digitGroups = (int) (Math.log10(availableSpace)/Math.log10(1024));
    return new DecimalFormat("#,##0.#").format(availableSpace/Math.pow(1024, digitGroups)) + " " + units[digitGroups];
}
