Singleton Method Gives Error In Onresum (android)
I have a problem that I could not understand why it is happening. I have a fragment, and in the fragment I have the on resume method as below: @Override public void onResume(){
Solution 1:
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
System.out.println("number 1");
int s = ((MainApplication) this.getActivity().getApplication()).getRefreshNotificationVar();
System.out.println("number 2");
s = s + 1;
System.out.println("number 3");
((MainApplication) this.getActivity().getApplication()).setRefreshNotificationVar(s);
System.out.println("number 4");
System.out.println(s);
}
Looks Like Activity Instance is null . Instead of onresume do the same operation on onActivityCreated Method . Please refer the above code.
