If you download a texting/SMS replacement app like GO SMS and Textra, all you have to do is download the Emoji plugins for either app and you'll have access to all iOS Emojis in a heartbeat.
Android currently doesn't allow for Emojis to be fully integrated into the on screen keyboard, which means that unfortunately, you can often see (but not access for your own use) emojis in tweets or Instagram posts. I hear that Android 4.3, the newest software release, may solve this problem, but it's unclear (as is unclear whether the Lucid will even get that update on your carrier or period).
But not too much of a big deal - I'm willing to sacrifice Emoji functionality on Twitter and Instagram as long as I have access to it when texting. GO SMS and Textra (with separate emoji plugin apps) are perfect in that regard - and I would highly recommend both.
