A missing class

[mariam-wahba]

Hello,
I cloned the project and I have the latest version code which is 2.5.5. I try to run the android app project and I get this error > Task :Anyplace:compileDebugJavaWithJavac
anyplace/clients/android/Anyplace/src/com/dmsl/anyplace/nav/BuildingModel.java:47: error: cannot find symbol
import com.dmsl.anyplace.tasks.FetchFloorsByBuidTask;
^
symbol: class FetchFloorsByBuidTask
location: package com.dmsl.anyplace.tasks
anyplace/clients/android/Anyplace/src/com/dmsl/anyplace/nav/BuildingModel.java:48: error: package com.dmsl.anyplace.tasks.FetchFloorsByBuidTask does not exist
import com.dmsl.anyplace.tasks.FetchFloorsByBuidTask.FetchFloorsByBuidTaskListener;

and i found out that there are many classes are using them but the FetchFloorsByBuidTask Class and the listener FetchFloorsByBuidTaskListener don't exist in the anyplace/clients/android/Anyplace/src/com/dmsl/anyplace/task as they should be ?!!!

have you changed the names of deleted them??!! and what will replace them as they are other classes use them?
