Android – Check whether the SD-card is available or not

Problem: How to check whether the SD-card is available or not programmatically?

Solution:

boolean isSDPresent = android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED);

if(isSDPresent)
{
  // yes SD-card is present
}
else
{
 // Sorry
}
