回答1:
It's may be because of not overwrite onResume() method you must overwite and restore your save-instance that previous store
回答2:
This is a bug in support package.To avoid this you can use following during fragment transaction.
transaction.commitAllowingStateLoss();
If you google it you'll find many good answers to it.For more reference and alternate methods see this SO post and this SO post.Hope it helps.
回答3:
You probably have a non-static subclass (I'm guessing it's a fragment) that your activity fails to instantiate every time it is resumed. In case you have such subclass, just make it static.
回答4:
It's may be because of using add() method many times with public method like
public void beginTransaction(ID id, Bundle bundle)
Avoid using
fragmentmanager.begintransaction().add
each time,
Use this too for replacing
fragmentmanager.begintransaction().replace(r.id.frame_container, fragment).commit()
