Attualmente sto utilizzando parse.com come soluzione di back-end per la mia app per Android. Sto cercando di utilizzare Facebook per autenticare gli utenti e attualmente sto riscontrando gli errori di seguito. Ho provato ad aggiungere sia JARS (Parse e Facebook) al mio progetto. Ho anche pulito il mio progetto più volte, ma ho ancora ottenere gli errori di seguito:NoClassDefFoundError quando si utilizza Parse.com per accedere a Facebook
Registro errori:

Sono i barattoli nella cartella '/ libs'? –
Prova [this] (http://stackoverflow.com/questions/13964392/im-getting-a-java-lang-classnotfoundexception-com-mysql-jdbc-driver/13964418#13964418). Anche il jar dovrebbe essere nella cartella libs, come già detto da Raghav :) – Ahmad
@RaghavSood il jar Parse e il jar di supporto Android di facebook sono entrambi nella cartella libs, ho ancora gli stessi errori. – AndroidEnthusiast
