Get the available space on the all the SD-cards

Question

I've found a very good method to get paths to all the sd-cards that device has,not only Environment.getExternalStorageDirectory() , but also external ones. This method is secrond at How can I get external SD card path for Android 4.0+?

So, my question is how can I find out free available space on sd card knowing it's path, for example, "storage/extSdCard" or any other

in other words i need a method :

public int getExternalAvailableSpaceInBytes(String sdRootPath) {
//here's this method using this sdRootPath
}

StatFs stat = new StatFs(Environment.getExternalStorageDirectory().getPath());
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2){
@SuppressWarnings("deprecation") 
long sdAvailSize = (long)stat.getAvailableBlocksLong() * (long)stat.getBlockSizeLong(); 
}
else{
@SuppressWarnings("deprecation")
double sdAvailSize = (double)stat.getAvailableBlocks() * (double)stat.getBlockSize();
}

double gigaAvailable = sdAvailSize / 1073741824;    //1073741824 =1GB

I specified that Environment.getExternalStorageDirectory().getPath() returns only internal SD card if 2 exists. I need to know available space by path of Sd-card. – Vlad Alexeev Sep 12 '14 at 13:39
pass the path of other SD cards which are punted instead of `Environment.getExternalStorageDirectory().getPath()` – Sagar Pilkhwal Sep 12 '14 at 13:40

how ? something like StatFs stat = new StatFs(new File(sdRootPath)); where sdRootPath is a String? – Vlad Alexeev Sep 12 '14 at 13:44
I gave this same link in my question above – Vlad Alexeev Sep 12 '14 at 13:44
StatFs takes String parameter as an argument so provide the path of your SD cards – Sagar Pilkhwal Sep 12 '14 at 16:29
