wish helps you EDIT: I tested your code and it works. You need read write permissions!
Add these to the manifest
code :
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
public void checkWritePermissions(){
    // Here, thisActivity is the current activity
    if (ContextCompat.checkSelfPermission(this,
            Manifest.permission.WRITE_EXTERNAL_STORAGE)
            != PackageManager.PERMISSION_GRANTED) {

        // Permission is not granted
        // Should we show an explanation?
        if (ActivityCompat.shouldShowRequestPermissionRationale(this,
                Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
            // Show an explanation to the user *asynchronously* -- don't block
            // this thread waiting for the user's response! After the user
            // sees the explanation, try again to request the permission.
        } else {
            // No explanation needed; request the permission
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1); //1 is the requestCode
        }
    } else {
        // Permission has already been granted
        writeFile(); //Or maybe return a bool value, true or false
    }
 @Override
public void onRequestPermissionsResult(int requestCode,
                                       String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case 1: { //CODE 1
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // permission was granted, yay! Do the
                // WRITE_EXTERNAL_STORAGE-related task you need to do.
                //Continue and write the file
            } else {
                // permission denied, boo! Disable the
                // functionality that depends on this permission.
                //Maybe display a message or something
            }
            return;
        }

        // other 'case' lines to check for other
        // permissions this app might request.
    }
}
 //Lets make a new DIR
 if (!file.getParentFile().exists()){
   file.getParentFile().mkdirs();
 }

if(!file.exists())
{
    file.createNewFile();
    new AlertDialog.Builder(this).setTitle("File Created").setMessage("File successfully created!").show();
}

I wish this helpful for you Well if you need compatibility with API level 7 and lower, use getExternalStorageDirectory() method. Also note that staring from API level 4 you have to request permission to write onto SD card:
code :
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Does that help I realised the reason it wasn't saving sometimes was because I was taking the SD card out of the phone before it had the chance to save.

To fix this issue I'm trying to write a file on SD Card but I'm unable to do it. Can you help me debug the code?
code :
File mydir = new File(Environment.getExternalStorageDirectory() + "/" +directoryName); //Creating an internal dir; 
    if(!mydir.exists())
        mydir.mkdir();

    File fileWithinMyDir = new File(mydir, fileName+".pList"); //Getting a file within the dir. 
    FileOutputStream fos = new FileOutputStream(fileWithinMyDir);

With these it helps getExternalStorageDirectory() does not necessary return /sdcard directory. See here Environment.getExternalStorageDirectory does not return the path to the removable storage
