Attempt to invoke virtual method 'android.os.Parcelable android.os.Bundle.getParcelable(java.lang.String)' null object reference

Question

I am making an app in which a feature that user can upload images and video to server it was working well on activity but now I want to use it in a fragment. I try to code effectively, efficiently and I am not getting any error during compiling and my app runs successfully but when I click on fragment it shows "unfortunately app has stopped " and in log cat I am getting this error:

java.lang.NullPointerException: Attempt to invoke virtual method 'android.os.Parcelable android.os.Bundle.getParcelable(java.lang.String)' on a null object reference

and its points this line:

 public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
   this line  ➦   fileUri = savedInstanceState.getParcelable("file_uri"); 
    }

i don't know whats wrong

my code:

public class TabFragment4 extends Fragment implements  View.OnClickListener{

Answer 1

Uri imageUri = data.getData();
            Bitmap bitmap= null;
            try {
                bitmap = MediaStore.Images.Media.getBitmap(getContext().getContentResolver(), imageUri);
            } catch (IOException e) {
                e.printStackTrace();
            }

Answer 2

Seems savedInstanceState == null so use something like this:

if (savedInstanceState != null) {
    fileUri = savedInstanceState.getParcelable("file_uri"); 
} else {
    fileUri = ??? - what You want do to in else case;
}
