ShootNup: Upload su ImageShack dal tuo cellulare
Ho finalmente terminato la mia ultima applicazione: ShootNup. Come suggerisce già il titolo (shoot and upload), quest’applicazione permette di caricare le tue foto online su ImageShack, direttamente dal cellulare.
Tra le varie opzioni, è possibile selezionare come oggetto dell’upload una foto salvata in memoria oppure uno screenshot dello schermo del cellulare.
Una volta che l’immagine è stata inserita online, verrà restituito il link diretto ad essa che sarà conservato per tutta la sessione di lavoro.
L’applicazione fa uso della connessione ad internet, e dato il grande numero di dati che viene trasferito (a causa del peso delle immagini) si consiglia l’utilizzo di una connessione wi-fi o di un abbonamento ad internet.
Questo programma è scritto in Python e richiede ovviamente che l’interprete del linguaggio sia installato sul vostro cellulare. Oltre a ciò utilizza due moduli esterni, che sono appswitch e dialog: il primo serve a passare l’applicazione dalla modalità background a foreground quando si salva uno screenshot, il secondo serve per mostrare le schermate di stato (caricamento in corso, upload in corso, ecc.). Non essendo strettamente necessari per l’upload, potete anche non installarli, ma li ho inclusi nel file .zip che segue e consiglio caldamente di installarli.
