if (isExteranlStorageAvailable()) {
try {
File input = new File("/sys/class/mmc_host/mmc1");
String cid_directory = null;
int i = 0;
File[] sid = input.listFiles();

for (i = 0; i < sid.length; i++) {
if (sid[i].toString().contains("mmc1:")) {
cid_directory = sid[i].toString();
String SID = (String) sid[i].toString().subSequence(cid_directory.length() - 4,cid_directory.length());
Log.d(TAG, " SID of MMC = " + SID);
break;
}
}
BufferedReader CID = new BufferedReader(new FileReader(cid_directory + "/cid"));
String sd_cid = CID.readLine();
Log.d(TAG, "CID of the MMC = " + sd_cid);
tv.setText("CID of the MMC = " + sd_cid);

} catch (Exception e) {
Log.e("CID_APP", "Can not read SD-card cid");
}

} else {
Toast.makeText(this, "External Storage Not available!!",Toast.LENGTH_SHORT).show();
}

}

private boolean isExteranlStorageAvailable() {
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state)) {
return true;
}
return false;
}
