To use the Dropbox API v2 in Android, you should use the API v2 Java SDK:

https://github.com/dropbox/dropbox-sdk-java

There isn't a step by step tutorial for that in particular, but there's an example Android app that uses it included with the SDK:

https://github.com/dropbox/dropbox-sdk-java/tree/master/examples/android

You should refer to that as an example of how to implement the app authorization flow, which is accomplished via OAuth 2.

Your AndroidManifest.xml should be set up as shown here:

https://github.com/dropbox/dropbox-sdk-java/blob/master/examples/android/src/main/AndroidManifest.xml#L33

You start the flow by calling startOAuth2Authentication as shown here:

https://github.com/dropbox/dropbox-sdk-java/blob/master/examples/android/src/main/java/com/dropbox/core/examples/android/UserActivity.java#L35

You complete the flow by calling getOAuth2Token as shown here:

https://github.com/dropbox/dropbox-sdk-java/blob/master/examples/android/src/main/java/com/dropbox/core/examples/android/DropboxActivity.java#L22

Your app can store and re-use the resulting access token for that user, as the example does here:

https://github.com/dropbox/dropbox-sdk-java/blob/master/examples/android/src/main/java/com/dropbox/core/examples/android/DropboxActivity.java#L24

To download files, you can use the download method as shown here:

https://github.com/dropbox/dropbox-sdk-java/blob/master/examples/android/src/main/java/com/dropbox/core/examples/android/DownloadFileTask.java#L69
