If you're entirely new to smartphones, Android's share menu can seem like a foreign concept at first glance. In reality, it's one of Android's most central and unique features, and with a little experience, it can make your smartphone a lot easier to use.
Android allows all apps to share data with each other. For instance, if you're viewing a picture in your favorite gallery app, you can share this image over to any email app, where you can then send it to anyone. Or if you're looking at a web page in your browser, you can share the link over to any text messaging app and send it to your friend.
This is the essence of Android's share menu, and it's available in almost all apps. Whenever you see the icon below, that means you can send the file you're currently viewing over to a different app or service.

Using the Share Menu
The share button is not always in the same place, since it's up to the app's developer to choose where to put it. Most of the time, you'll see the share button directly beneath the file you're currently viewing, but sometimes, you'll have to tap the three-dot menu button in the top-right corner of your screen to access the share feature.

Either way, once you press the share button, you'll see Android's share menu. This is asking which app you'd like to send the file or link to, so select the target app from this list.
At this point, the file you shared will be queued up and ready to use in the target app. For example, when sharing a picture to the Gmail app, the photo will already be attached and ready to send to any recipient.
