You can use getExternalStorageState(). The developer's site ( indicated here ) contains a short fragment of the recommended method for checking the availability of an external SD card, and regardless of whether it can write to it.

It works and is very easy to understand.

 TextView state = (TextView) findViewById(R.id.sdcardstatus);
  if(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED))   {
  state.setText("SD card is present");
} else {
 state.setText("SD card is not present");
 }

Or refer to this tutorial

HAPPY CODING!
