This application is pretty easy to use with Android. I use a Samsung Galaxy Note 5 and the phone email client allows the use of encryption. Once you setup the application and make your keys all you need to do is sent an email. Write an email as you normaly would then, click on More and choose Security Options. Pick the key that you are going to use, you can make more than 1 key. Very easy to do. Also, you can set the email client to always to encrypt and/or sign.

The application is in the Play Store.
