Check whether the SD card is available or not programmatically

Question

My app is working for mobiles which have an SD card only. So programmatically I want to check if the SD card is available or not and how to find the SD card free space. Is it possible?

If yes, how do I do it?

Answer 1

Boolean isSDPresent = android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED); Boolean isSDSupportedDevice = Environment.isExternalStorageRemovable();  if(isSDSupportedDevice && isSDPresent) {   // yes SD-card is present } else {  // Sorry } 

Answer 2

Accepted answer doesn't work for me

Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED); 

In case if device has a built-in storage, it returns true; My solution is that to check the external files directory count, if there is more than one, device has sdcard. It works and I tested it for several devices.

public static boolean hasRealRemovableSdCard(Context context) {     return ContextCompat.getExternalFilesDirs(context, null).length >= 2; }
