I have followed ViewPager FragmentPagerAdapter Nullpointer but no help. Any solution to it would be appreciated. Please note that i have imported classes from Support library only. 

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v4.view.ViewPager.OnPageChangeListener;

Here is the crash log I received in Splunk Mint

    Hint from the question you linked: "Examine your `getItem(int index)` method very closely and look for any logic, scenarios or missing 'break' statements which might cause you to end up with a null fragment." On exception you're returning nulls. – laalto Jun 10 '16 at 07:20
  • @jankigadhiya there is no such class you specified. – Divyang Pathak Jun 20 '16 at 14:13

use 

try {
    // you full code here
} catch (NullPointerException n){
    Toast.makeText(getApplicationContext(),n.toString(),Toast.LENGTH.LONG).show();
}

this will show you the full detail of exception. Hope this will help you to reach at the error.

  • Thanks Teerath, but I have already implemented a code which sends a stacktrace email to me in the catch block. One more thing, I would like add here is, it not frequent, it is like I am keeping the application open for 6-7 hours and then navigating to the screen wherein these fragment adapter is set for showing the Help Wizard screen and the application crashes with NullPointerException. – Divyang Pathak Jun 10 '16 at 08:11
