Wow, Firefox Send is a great service from Mozilla.
Now you can send anonymously and encrypted files with a date or download limit to anyone. Forget the times where you need to use proprietary services like Google Drive or depend on that 25MB filesize limit of your mail-provider.
Just send a link and you're good to go. You can even choose to set a password for this file.
The site https://send.firefox.com was already up for a few weeks, now the app for Android is ready to share directly from almost any app. Thanks Mozilla!
Get the Firefox Send App in the Google Playstore
