 In BMB, cache optimization is apply for avoiding re-create boom-buttons every time it booms. With cache optimization, boom-buttons will not be removed so that they are not necessary to re-create, which can optimize the resource. The default value for cache optimization is true, you can turn it off by:
 ```
 bmb.setCacheOptimization(false);

 Notice that when bmb is used [in fragment](https://github.com/Nightonke/BoomMenu/wiki/Use-BMB-in-Fragment) or [in list](https://github.com/Nightonke/BoomMenu/wiki/Use-BMB-in-List)(list-view/recycler-view), cache optimization is turned off automatically.
