java.lang.IllegalStateException: commit already called in view pager with Tablayout

I am using View pager with Tablayout in my project. I am continuously getting crash report on crashlytics. Below is the stack trace.

I am setting tablayout like this in java code

I have gone through all possible solutions available for this error..But none of them is working. I am unable to trace what is causing this exception.Any help will be appreciated.

Apparently commit() or commitAllowingStateLoss() happens twice inside FragmentStatePagerAdapter . Here what I found out from android sources:

The only place from where the transaction of this adapter is commited is FragmentStatePagerAdapter.finishUpdate() and it’s commitAllowingStateLoss() version of commit() . Hence, finishUpdate() is called twice. This method is called from 3 places:

Now, finishUpdate() is protected by if (mCurTransaction != null) check and inside this check mCurTransaction is nulled. Hence we cannot really commit the same transaction twice. Unless we have multiple threads working on it. mCurTransaction field is not volatile, which leads me to idea that you’re probably calling (directly or indirectly) one of the methods listed above from the worker thread and sometimes it leads to a race condition around mCurTransaction field, which leads to a second commitAllowingStateLoss() call.

Make sure you’re referencing your adapter and related objects only from main (UI) thread.

Я устанавливаю tablayout, как это в java-коде

Я воспользовался всеми возможными решениями, доступными для этой ошибки. Но ни один из них не работает. Я не могу отследить, что вызывает это исключение. Любая помощь будет оценена.

Проанализируйте причины

Причина, по которой сообщается об этой ошибке, заключается вFragment Дела — это глобальная переменная, которая может быть совершена только один раз.

Решение:

Определите фрагментную транзакцию как локальную переменную и получайте новые транзакции каждый раз, когда вы отправляетесь в коммит.
