How to check Phone internal/external memory usage using programmatically in android
Android have a default API to check the phone internal and external memory usage.In My application
i used both as well as memory informations.The internal and external both are same,just to change
the Environment path.
Internal=StatFs stat=new StatFs(Environment.getDataDirectory().getPath());
External=StatFs stat=new StatFs(Environment.getExternalStorageDirectory().getPath());
External=StatFs stat=new StatFs(Environment.getExternalStorageDirectory().getPath());
The user can just hit the seek bar its show the occupied space in bytes,availabel space in MB,
Before that first to create new emulatore with size can set it in Kb or MB.I used 24MB.

you may check in console also or u can clarify the usage in phones settings. go to settings/SD card & phone storage/
