Fence API - the final bits You can remove fences : 
 FenceUpdateRequest.Builder builder = new FenceUpdateRequest.Builder();
 builder.removeFence(“fenceKey”); And also query them directly : FenceQueryRequest queryAll = FenceQueryRequest.all();
 FenceQueryRequest querySome = FenceQueryRequest.forFences("headphone", "walking");
 
 Awareness.FenceApi.queryFences(googleApiClient, queryAll)
