Select & delete all emails in android (at least 2.2)
I've looked at this most of the day today and find that -- at least with Android 2.2 -- there is no way to select all emails and delete them. If you select multiple emails, there is an option to unselect them all, but not to "select all". Being 2012, how crazy is that? And not only that, if I manually delete emails, it moves them to the trash, and there is no way to "empty the trash" without selecting the emails one at a time and deleting them again.
However, after looking at this for an extended period of time...I figured out that the default Email app on android 2.2 does not handle POP3 accounts like most email programs handle POP3 accounts. It downloads email from the server, but leaves a copy on the server. But if you delete the email from the server, it will delete them from your phone. Again, that's not typically the way POP3 email works.
I've looked for email apps all afternoon in an attempt to find one where the programmers were smart enough to put a delete all button on the phone, but since I figured out I can just delete them from the server and have it also delete them from my phone, I can live with that. I get a lot of email, though, and what I didn't want to do was have to individually select 500 emails to delete, and then have to go to the trash and do it again.
They could be a little more clear on this.
