can't use withUseDefaultSession

[moshlp]

how is withUseDefaultSession used? because I need to use the session that is registered on the mobile, but with withUseDefaultSessio=true and no username and no password I get java.lang.IllegalArgumentException: You didn't set a Gmail username

@moshlp withUseDefaultSession(true) is not used to send the email with current session of signed in email account in settings or gmail app. Check out more about the purpose of withUseDefaultSession at yesidlazaro#21

thanks for answering, is there any way to use the signed credentials?
