Sto creando un'app per Android che selezionerà semplicemente un'immagine dalla sdcard (galleria del telefono) e la memorizzerà nell'unità Google. Ho fatto un grande sforzo su questo, ho preso l'aiuto dal codice fornito dagli sviluppatori di Google su drive quick start. Ho fatto un controllo Button nel mio file main.xml, quando fare clic su questo pulsante che serve all'interno della galleria di telefono e quando seleziono un quadro non sta succedendo nienteseleziona l'immagine dalla sdcard e la memorizza nell'unità google
Questo è Log gatto dal mio IDE Eclipse

qualsiasi aiuto sarà apprezzato. Grazie in anticipo
Grazie per la vostra riproduzione in realtà errore viene risolto da me, ora, dopo l'esecuzione dell'applicazione tutto sta andando bene né forza vicino né alcun altro errore, ma nella scheda di debug sto ottenendo questo messaggio "la fonte allegato non contiene la fonte per il file basedexclassloader.class ". Sebbene la sorgente sia impostata come "sdk \ platforms \ android-17 \ android.jar". Aiutatemi, il file non viene caricato sull'unità per questo o per altri motivi? e se questo non è il motivo per caricare il file, allora perché il mio file selezionato dalla galleria non sta caricando .... Grazie in anticipo –
