NullPointerException in android studio google maps v2 project (Draw Route)

Question

I want to create a route beetween two point in google maps android api v2. I'm following a great and simple answer in Stackoverflow.

I'm using android Studio template for google maps, I get an exception in the execution of my code but I don't know why, this is the error:

the lines that contains errors : enter image description here

UPDATE : I tried to change the call of this class but I still get the two first problems.

(1) Are you sure you are getting this exception during *compilation*, and not during execution? (2) Where is line 112 in your code? — cybersam, May 23 '14 at 22:02
I'm sorry it's a mistake , it's during the execution ! and the line 112 is in the first picture that have number 1 and is selected with yellow — AndroLife, May 23 '14 at 22:06
`doc` is `null`. Which means that `md.getDocument` is returning a `null` value. — Code-Apprentice, May 25 '14 at 00:35
yes but how can I solve that problem ? because the class work for the others but me no. @Code-Guru — AndroLife, May 25 '14 at 01:54
md is object of class GMapV2Direction , it's declared in onCreate() method — AndroLife, May 25 '14 at 03:03

setUpMap() is passing a null value to getDirection().

Thank you ! but what do you suggest to solve this problem please ? – AndroLife May 23 '14 at 22:11
So getDirection(); is the method that give me this error ? @cybersam – AndroLife May 23 '14 at 22:32
Yes. The stack trace says that the `NullPointerException` is occurring at line 112. – cybersam May 23 '14 at 22:58
