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 "???";
}
