External Storage issue in android

Question

I am using the path as "/mnt/sdcard/myfolder/myfile" to store my file in android app. Will it give any error when the app running on the phone which does not have any sdcard slot(phone like Nexus S)?

Use the location from /sdcard/myfolder/myfile, /mnt is not necessary. To check the availability of sdcard you can use, android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED); — Jibran Khan, Apr 03 '13 at 05:45
Also note that you shouldn't use a hardcoded path to access external storage. If you are not already, you should be using Environment.getExternalStorageDirectory(). — Brett Duncavage, Apr 03 '13 at 05:56

You have to check whether external storage is available or not

private static boolean isExternalStorageAvailable() {
    String extStorageState = Environment.getExternalStorageState();
    if (Environment.MEDIA_MOUNTED.equals(extStorageState)) {
        return true;
    }
    return false;
}

Please check this link :

boolean mExternalStorageAvailable = false;
boolean mExternalStorageWriteable = false;
String state = Environment.getExternalStorageState();

if (Environment.MEDIA_MOUNTED.equals(state)) {
    // We can read and write the media
    mExternalStorageAvailable = mExternalStorageWriteable = true;
} else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) {
    // We can only read the media
    mExternalStorageAvailable = true;
    mExternalStorageWriteable = false;
} else {
    // Something else is wrong. It may be one of many other states, but all we need
    //  to know is we can neither read nor write
    mExternalStorageAvailable = mExternalStorageWriteable = false;
}
