The method of obtaining SDcard card information by Android programming _android

The example in this article describes how Android programming obtains SDcard card information. Share to everyone for your reference, specific as follows:

public static Sdcardinfo Getsdcardinfo () {String sdcstring = Android.os.Environment.getExternalStorageState (); if (Sdcstring.equals (Android.os.Environment.MEDIA_MOUNTED)) {File Pathfile =
   Android.os.Environment.getExternalStorageDirectory ();
    try {android.os.StatFs statfs = new Android.os.StatFs (Pathfile.getpath ());
    Gets the total number of blocks on the sdcard long ntotalblocks = Statfs.getblockcount ();
    Gets the size long nblocsize = Statfs.getblocksize () of each block on the sdcard;
    Gets the number of blocks that can be used by the program long Navailablock = Statfs.getavailableblocks ();
    Gets the number of all remaining blocks (including chunks that are not used by the reserved general program) long Nfreeblock = Statfs.getfreeblocks ();
    Sdcardinfo info = new Sdcardinfo ();
    Calculates sdcard Total capacity MB Info.total = Ntotalblocks * nblocsize;
    Calculates sdcard remaining size MB Info.free = Navailablock * nblocsize;
   return info;
   catch (IllegalArgumentException e) {log.e (Log_tag, e.tostring ());
} return null;
} sdcardinfo Sdcardinfo = Util.getsdcardinfo (); SD Card Total Capacity SdcardinFo.total//SD card remaining capacity Sdcardinfo.free
