In FragmentManager in Android, the main commit methods are used to apply fragment transactions. The main types of commit methods:

  • commit() — performs the transaction asynchronously; changes will be applied in the future when the system is ready.
  • commitAllowingStateLoss() — similar to commit(), but allows executing the transaction even if the activity state has already been saved (which may lead to state loss).
  • commitNow() — performs the transaction synchronously immediately, blocking the current thread until completion.
  • commitNowAllowingStateLoss() — synchronous execution with allowance for state loss.

The choice of method depends on the situation: if you need to apply changes immediately — commitNow(), if you can delay — commit(). Using methods with AllowingStateLoss requires caution, as it can lead to unpredictable behavior during state restoration.
