# #26 A Tile Like Any Other

An app that is reached by pasting a URL is a demo. It becomes an application
when it has a tile — and in the launchpad an abap2UI5 app is indistinguishable
from the RAP and freestyle tiles beside it. Same shell, same theme, same back
button, same "who built this one again?" from the person supporting it.

**What is installed once.** The launchpad loads a UI5 app from the system's
UI5 repository, so the abap2UI5 shell has to exist there as one: the
[launchpad connector](https://github.com/abap2UI5-addons) ships it through
abapGit, as app `z2ui5`. That is one deployment for the whole system, not one
per app — every abap2UI5 tile you ever create points at the same shell.

**What is configured per app.** A target mapping, with the app class as the
parameter:

| | |
|---|---|
| Semantic Object | `Z2UI5_CL_MY_APP` |
| Action | `display` |
| URL | `/sap/bc/ui5_ui5/sap/z2ui5` |
| Parameter | `app_start` / `Z2UI5_CL_MY_APP` |

A tile, a catalog, a role — the Fiori administration the system already does,
with nothing abap2UI5-specific in it except that last parameter.

**What the app can do inside.** It knows where it is:

```abap
    IF client->get( )-check_launchpad_active = abap_true.
      client->follow_up_action( val   = client->cs_event-set_title_launchpad
                                t_arg = VALUE #( ( `Job Monitor` ) ) ).
    ENDIF.
```

Startup parameters from the target mapping arrive in
`client->get( )-t_comp_params`, and navigation to another *Fiori* app goes
through the launchpad's own cross-app navigation, so the shell's back button
keeps working.

**What to do when the tile is blank.** Because it will be, once. The one
recurring trouble is not the app but the UI5 app index after an abapGit import:
run `/UI5/APP_INDEX_CALCULATE`, clear the HTTP cache in `SMICM`, hard-reload.
The [launchpad page](/configuration/launchpad) walks through it with
screenshots. Bookmark it now and save yourself the twenty minutes.

Public Cloud is a different door: there the launchpad is Build Work Zone, and
the [ABAP Cloud pages](/configuration/btp) describe the setup.

One shell in the UI5 repository, one parameter per tile. No user can tell
the difference.
