Question

Access USB Device Memory through programmatically.

1. Get USB Device Total Memory Size.
2. Get USB Device Total Free(Available) Memory Size.

I know the memory size of Internal/External Memory

File path = Environment.getDataDirectory();
StatFs stat = new StatFs(path.getPath());
long blockSize = stat.getBlockSize();
long availableBlocks = stat.getAvailableBlocks();
String availableMemory =  Formatter.formatFileSize(this, availableBlocks * blockSize);
Log.i("","Available MB : " + availableMemory);

In this code does not worked for identifying the USB Device Memory.

How do find the USB Device Memory.

Thanks in advance.

Hi Please use below code…

     StatFs statFs = new StatFs(Environment.getExternalStorageDirectory().getAbsolutePath());        
     long blockSize = statFs.getBlockSize();
     long totalSize = statFs.getBlockCount()*blockSize;
     long availableSize = statFs.getAvailableBlocks()*blockSize;
     long freeSize = statFs.getFreeBlocks()*blockSize;

And If you fine in MB then

long megAvailable = availableSize/ (1024 * 1024);
Log.e("","Available MB : "+megAvailable);
