Method of obtaining path and residual capacity of SD card by Android programming

This paper describes the method of obtaining SD card path and remaining capacity by Android programming. Share it for your reference, as follows:

public static String getExternalStoragePath() {
 //  Get SdCard Status 
 String state = android.os.Environment.getExternalStorageState();
 //  Judge SdCard Does it exist 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) {
 //  Acquire sdcard File path 
 StatFs statFs = new StatFs(filePath);
 //  Get block Adj. SIZE
 long blocSize = statFs.getBlockSize();
 //  Get BLOCK Quantity 
 // long totalBlocks = statFs.getBlockCount();
 //  Available Block Quantity of 
 long availaBlock = statFs.getAvailableBlocks();
 // long total = totalBlocks * blocSize;
 long availableSpare = availaBlock * blocSize;
 return availableSpare;
}
