• Dipen Shah: Have you tried turning this off?
• user5292387: I think your question was already answered here: [stackoverflow.com/questions/2020088/… [1]: stackoverflow.com/questions/2020088/…
• Bill Shannon: You also might want to try this development version of JavaMail for Android, especially if you want to use OAuth2 authentication instead of enabling support for less secure apps.

Answer 1

You need to properly setup your Gmail account.

If you have 2-step verification enabled:

• Please follow this tutorial to create an app password for your app.

If you don't have 2-step verification enabled:

• Simply enable less secure apps login here.

I don't recommend it, though. I believe your password is stored in plain text as a String value, right?
A little bit of reverse engineering and it's out in the public.

• Abdul Rahman Majeed: yes I have enable now , but still got authentication failed exception
• Paulo Avelar: Great! If my answer helped you on that, please mark it as correct. Otherwise, I recommend you answer this question yourself with details on how you fixed it. :)
