Hi!,

So I got this code from HERE to try and save an inventory:

 var button = new android.widget.Button(ctx);
 button.setText("Save Inventory");
 button.setOnClickListener(new android.view.View.OnClickListener({
 onClick: function(viewarg){
 
 function saveFile (directory, inventory) {
 try {
 directory = android.os.Environment.getExternalStorageDirectory ().getPath () + "/games/com.mojang/minecraftworlds" + getWorldDir () + "/" + directory; // The file should be saved into the world directory.
 var newFile = new java.io.File (directory,inventory);
 var directory = new java.io.File (directory);
 var success = directory.mkdirs (); // creates the directory if not already created
 if (!success){ // if not succeeded
 throw new java.io.IOException("Directory "+directory+ "cannot be created"); // throws an IOException. new java.io.IOException(String) has a string parameter as a message.
 }
 
 newFile.delete();
 /*newFile.createNewFile (); // creates a blank new file*/
 var outWrite = new java.io.OutputStreamWriter (new java.io.FileOutputStream (newFile)); // creates the output writer
 outWrite.append (Player.getInventorySlot(i));
 outWrite.close(); // closes the writer; not necessary to close, but better do it
 return false; // tells that it succeeds; not necessary to catch, but better do it
 }
 catch(thrown){ // catches the error in the try block
 return thrown.toString(); // returns a human-readable description of the error. The most common one is java.io.IOException that there is no such file
 }
 }

function readFile (directory, inventory, wantBytes) { // wantBytes: true or false
 try{
 directory = android.os.Environment.getExternalStorageDirectory ().getPath () + "/games/com.mojang/minecraftworlds" + getWorldDir () + "/" + directory;
 var inFile = new java.io.File(directory,filename);
 if (!inFile.isFile()) return "notfile"; // check if it is a file
 var inStream = new java.io.FileReader (inFile);
 if (wantBytes) {
 inStream.read (bytes); // stores the contents into bytes
 var bytes = new Array();
 return bytes;
 }
 var inBuffer = new java.io.BufferedReader (inStream);
 var line = "",var returner = "";
 while ((line = inBuffer.readLine ()) != null) { // read http://docs.oracle.com/javase/7/docs/api/java/io/BufferedReader.html#readLine()
 returner = returner + line + java.lang.System.getProperty ("line.seperator");
 }
 return returner;
 }
 catch(error){
 return error.toString();
 }
 }
 }
 }));
 menuLayout.addView(button); 

And now its crashing because I dont know what to put in

 var line = "",var returner = ""; 

Thank you VERY much!
