La mia applicazione è collegata ad una lampada tramite Bluetooth e praticamente ha 16 schermate, 3 di cui spiega l’utilizzo della lampada e del app, una schermata per scegliere la registrazione o l’accesso e in seguito ci sono la schermata per registrarsi e l’altra per accedere, una schermata per collegare il Bluetooth, un interfaccia che porta ad un altra schermata per che è collegata ad altre schermate, per poter aprire una schermata per scheggiare il colore della luce, poi un altra per poter scegliere la suoneria della sveglia compresa la musica, poi scegliere il font del display e in fine una schermata per l’orologio per inserire l’ora della sveglia e che possa mandare un messaggio al telefono del tipo “Buongiorno”, pero avendo questo problema non riesco a capire dove posso aver sbagliato potreste aiutarmi?
Remove your app icon or change it to be a png square up 1024x1024
Ho già provato o provato pure a toglierla ma da sempre problemi
can you share your aia?
If I remove your app icon it builds the apk correctly so, remove it or change it to a png square up 1024x1024
Changing that icon from jpeg to png it works.
Ho riprovato adesso grazie
