Il primo passaggio nella strutturazione della tua app multimediale consiste nel determinare quali categorie di contenuti vuoi che vengano visualizzate come opzioni di navigazione di primo livello nella barra dell'app.
Le case automobilistiche si occupano dell'implementazione della barra delle app e della determinazione della maggior parte degli aspetti del suo aspetto.
Fondamentalmente, devi decidere quanto segue:
