The method of acquiring SD card path and remaining capacity by Android programming _android

This article illustrates the method of acquiring SD card path and remaining capacity by Android programming. Share to everyone for your reference, specific as follows:

public static string Getexternalstoragepath () {
 //Get SDcard status
 string state = Android.os.Environment.getExternalStorageState ();
 To determine if sdcard exists and is available
 if (android.os.Environment.MEDIA_MOUNTED.equals (state) {
 if ( Android.os.Environment.getExternalStorageDirectory (). CanWrite ()) {return
   Android.os.Environment.getExternalStorageDirectory (). GetPath ();
 }
 return null;
}
public static long Getavailablestore (String filePath) {
 //Get SDcard file path
 statfs statfs = new Statfs (FilePath); c14/>//gets the size
 long blocsize = Statfs.getblocksize () of the Block;
 Gets the block number
 //Long totalblocks = Statfs.getblockcount ();
 The number of blocks that can be used
 long availablock = Statfs.getavailableblocks ();
 Long total = Totalblocks * blocsize;
 Long Availablespare = Availablock * blocsize;
 return availablespare;
}
