Android Device Total Internal Storage

Question

I'm trying to find out the total storage space a device has. I've tried:

StatFs statFs = new StatFs(Environment.getRootDirectory().getAbsolutePath()); 
statFs.getTotalBytes();
statFs.getBlockCountLong() * statFs.getBlockSizeLong();

and both methods return the same number, which is ~2GB , when I know that my device has 16GB total storage space (accessible and inaccessible).

How can I get the real storage size? Not only available or free space, every last scrap of a byte a device has.

Answer 1

What you probably need is this:

StatFs statFs = new StatFs(Environment.getDataDirectory().getPath()); 

because getRootDirectory(); gets you the "system" partition holding the core Android OS.

Then, the other method will get you the total storage space...
