Answer 1

The problem is simple here. You are creating a fragment and setting data to it which is fine,

AddExpenseFragment fragment=new AddExpenseFragment();
fragment.setArguments(bundle);

But the problem is in your

UiActivity.startAddExpense(context);

you must be replacing with a new instance of the AddExpenseFragment as you are no where passing the newly created fragment instance (with the arguments set to it) to the startAddExpense() method.

The solution is simple, just pass the newly created fragment object to the startAddExpense() like this,

UiActivity.startAddExpense(context, fragment);

and then inside the method replace or add this new fragment and do not instantiate any new fragment object.
