In this example we will see how to use Dropbox API to share Share file to Dropbox in from your
native Android application.
Creating an app on Dropbox
You can download Dropbox API (https://www.dropbox.com/developers/core/sdks/android)
from official source. The downloaded Zip will have sample and library. The Dropbox SDK gives
you a way to share files with a Dropbox account.
Before integrating Dropbox SDK to your android app you have to create a new app on Dropbox
developer console. Visit Dropbox developer console
(https://www.dropbox.com/developers/apps) and create a new application. Once you create the
application you will get an App key and App Secret.
Android app using Dropbox SDK
Now do the following changes to your application manifest file. Put the following code before
</application> tag. Make sure you are using your own AppID obtained from Facebook developer
console.
