You can have reference of the same kind of issue here https://stackoverflow.com/a/28673131/8473587 , Your Activity object might be null or else the refernace of Activity is not currect. — Hardik Vegad, Nov 05 '19 at 08:57
Intent activity2Intent=new Intent(getApplicationContext(), CameraActivity.class); startActivity(activity2Intent); Try Something like this — Ruben Meiring, Nov 05 '19 at 09:03
@Hardik Vegad I saw that link but still didn't figure out how to fix my problem — Mohammad Kazemian, Nov 05 '19 at 09:09
Actually the code you provided does not provide proper understanding of your main issue, I am posting an answer is you are talking about the intent that you have implmented to start the activity SaveNewFector.class then don't use the MainAcitivyt_mainActivity_ in 1st parameter of the intent, instead use SheetSaveNewFector.this. — Hardik Vegad, Nov 05 '19 at 09:18

i haven`t see you fragment in your code..
but i think.. maybe your network response comes too late, and after your fragment detach

Change the Intent to start the activity SaveNewFector.class

Intent intent=new Intent(SheetSaveNewFector.this,SaveNewFector.class);  
startActivity(intent);

Thank you. But SheetSaveNewFactor is not a Activity . SheetSaveNewFactor extends BottomSheetDialogFragment – Mohammad Kazemian Nov 05 '19 at 09:25
BottomSheetDialogFragment is itself had a context like dialog for that you can use only "this" to get the context, so in that case you might use getContent() for starting new activity, Like Intent intent = new Intent(getContext(),SaveNewFector.class); I suggest put some debug points and check on which exect line you are getting this crash. – Hardik Vegad Nov 05 '19 at 09:33
