I need to know how much internal space is left on device, but "internal" space no external SD c开发者_如何学Card.

This code is used for external SD space.

anyone know how to get the free internal space?

Thanks in advance.

The code you linked to is what you need. However, rather than:

StatFs stat = new StatFs(Environment.getExternalStorageDirectory().getPath());

use something like:

StatFs stat = new StatFs(getFilesDir().getPath());
