How to find the amount of free storage (disk space) left on Android? [duplicate]

Question

I am trying to figure out the available disk space on the Android phone running my application. Is there a way to do this programmatically?

Thanks,

Example: Getting human readable size like 1 Gb

String memory = bytesToHuman(totalMemory())

/************************************************************************************************* Returns size in bytes.  If you need calculate external memory, change this:      StatFs statFs = new StatFs(Environment.getRootDirectory().getAbsolutePath()); to this:      StatFs statFs = new StatFs(Environment.getExternalStorageDirectory().getAbsolutePath());         **************************************************************************************************/     public long totalMemory()     {         StatFs statFs = new StatFs(Environment.getRootDirectory().getAbsolutePath());            long   total  = (statFs.getBlockCount() * statFs.getBlockSize());         return total;     }      public long freeMemory()     {         StatFs statFs = new StatFs(Environment.getRootDirectory().getAbsolutePath());         long   free   = (statFs.getAvailableBlocks() * statFs.getBlockSize());         return free;     }      public long busyMemory()     {         StatFs statFs = new StatFs(Environment.getRootDirectory().getAbsolutePath());            long   total  = (statFs.getBlockCount() * statFs.getBlockSize());         long   free   = (statFs.getAvailableBlocks() * statFs.getBlockSize());         long   busy   = total - free;         return busy;     } 

Converting bytes to human readable format (like 1 Mb, 1 Gb)

    public static String floatForm (double d)     {        return new DecimalFormat("#.##").format(d);     }       public static String bytesToHuman (long size)     {         long Kb = 1  * 1024;         long Mb = Kb * 1024;         long Gb = Mb * 1024;         long Tb = Gb * 1024;         long Pb = Tb * 1024;         long Eb = Pb * 1024;          if (size <  Kb)                 return floatForm(        size     ) + " byte";         if (size >= Kb && size < Mb)    return floatForm((double)size / Kb) + " Kb";         if (size >= Mb && size < Gb)    return floatForm((double)size / Mb) + " Mb";         if (size >= Gb && size < Tb)    return floatForm((double)size / Gb) + " Gb";         if (size >= Tb && size < Pb)    return floatForm((double)size / Tb) + " Tb";         if (size >= Pb && size < Eb)    return floatForm((double)size / Pb) + " Pb";         if (size >= Eb)                 return floatForm((double)size / Eb) + " Eb";          return "???";     }
