Minimize App Produces Can not perform this action after onSaveInstanceState

Question

I'm making an async request with retrofit, on the middle of request i minimize the app and crash the app...

My log error:

java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState

Here it's the method I call if the request return success:

ActivityUtils.replaceFragmentToActivityWithBackStack(getFragmentManager(), IncompleteStatusFragment.newInstance(mLogin.getCustomerId(), mCustomer, prospect, mLogin), R.id.container_login);

Can someone help me?

That is obvious, if you minimize the app then you won't be able to replace the fragment as your app is not in focus & throw java.lang.IllegalStateException. you should probable maintain a flag & in onResume of your activity if that flag is true then replace the fragment.

like

@Override
public void onPause() {
   mIsActivityVisible = false;
}

@Override
public void onResume() {
   mIsActivityVisible = true;
   if(mShouldReplaceFragmentOnResume) {
      mShouldReplaceFragmentOnResume = false;
      // replace fragment
   }
}

// On Success response
onSuccessOfYourCall() {
   if(mIsActivityVisible) {
       //replace fragment
   } else {
       mShouldReplaceFragmentOnResume = true;
   }
}
