java - NullPointException on startActivityForResult(e.getIntent(), REQUEST_AUTHORIZATION); -

So I'm using Google Drive tutorials to help understand the basics of interacting with Google Drive and Works fine on code Samsung Ace 2 Android 2.3.6 is running, so I'm able to upload files to my Google Drive location. My point is that when I run the same application running Android 4.2.2 on my Samsung CII, it finds this account and allows me to upload a new file for uploading, but when I crash:

  startActivityForResult (e.getIntent (), REQUEST_AUTHORIZATION);   
 Logkat gives me the following:  
  03-26 18: 29: 39.686: E / Android Random (6775): Flat exception: Thread-256 03 -26 18: 29: 39.686: E / AndroidRuntime (6775): java.lang.NullPointerException 03-26 18: 29: 39.686: E / AndroidRuntime (6775): android.app.Activity.startActivityForResult (Activity.java: 3370) 03-26 18: 29: 39.686: E / AndroidRuntime (6775): android.app.Activity.startActivityForResult (Activity.java:3331) at 03-26 18: 29: 39.686: E / AndroidRuntime (6775): on Com .blitz_labs.Google $ 3.run (Google.java:209) 03-26 18: 29: 39.686: E / AndroidRuntime (6775): at java.lang.Thread.run (Thread.java:856)

 What could happen to anyone, what is happening due to this?  
 I've included the file upload function, where the error occurs.  
 Thank you in advance for your help.   
 
 
 You like stuff  
  last filelive files = request Exempt (); Request.setPageToken (files.getNextPageToken ());   
 If you receive a NPE on the second line, then you do not get the file as a result.  
 You should protect yourself against the incident as a code.  
  final file list file = request Exempt (); If (files! = Null) {request.setPageToken (files.getNextPageToken ()); }   
 Specifically, for your error, you have to preserve your code in such a way  
  if ((e! = Null) Amp; amp; (.getIntent ()! = Null)) {startActivityForResult (e.getIntent (), REQUEST_AUTHORIZATION); } And if (e = = null) {e.printStackTrace (); }
