Question

Answer 1

Just check whether activity is finishing or no, and then commit() the transaction.

if (!isFinishing()) {
    // commit transaction
}

The exception you get is in a scenario, when activity is being finished, and you are trying to commit a new transaction, which obviously won't be saved by FragmentManager because the onSavedInstanceState() has already been executed. That's why framework forces you to implement it "correctly".
