VI Hierarchies (Mobile Module)
Design Mobile VIs with wide, shallow VI hierarchies. Nested VI calls use large amounts of memory and might cause the Mobile VI to fail. Wide, shallow hierarchies have only a few VIs running at any time and use less memory.
Because of the different application structure on Mobile targets, Mobile VIs always start from one top-level VI and exit when that top-level VI completes. This behavior is different from a typical application you run on Windows in which you can start and run multiple top-level VIs simultaneously.
