回答1:

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:

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()

回答4:

It's may be because of not overwrite onResume() method you must overwite and restore your save-instance that previous store
