I have a bottom navigation activity ,In bottom navigation activity I have 3 icons Home,Reminders,settings.
For this I have 3 fragments, Home fragment, Reminder fragment and settings fragment. I don't have anything in fragments all are empty fragments except Home fragment. In Home Fragment I have a Tab layout but I didn't added anything with tab layout.
After running the project the Home fragment is not get displayed (default when app get launched). It shows only the bottom navigation view.
If I clicked on reminders Icon app get crashed with the following error.
Error:
java.lang.IllegalArgumentException: No view found for id 0x7f080076 (com.aviz.www.reminder:id/reminders_Fragment) for fragment Reminders{2eca87b #0 id=0x7f080076}

In Home.java all codes are auto generated code when I create the Home fragment.
