Android 移除fragment 标记

@Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
       
        /**
         * fragmentActivity 被回收时,里面保存的fragment不会销毁,会存到savedInstanceState中
         * 所以在创建时清除所保存的
         */
        if(savedInstanceState != null) {
            String FRAGMENTS_TAG = "android:support:fragments";
            savedInstanceState.remove(FRAGMENTS_TAG);
        }
        super.onCreate(savedInstanceState);


    
    }
