The documentation for Android BLE is here: http://developer.android.com/guide/topics/connectivity/bluetooth-le.html

We also have a couple of demo applications for Android, for which source code is available if you have a product key for one of our kits: https://www.nordicsemi.com/Products/nRFready-Demo-APPS

Ah yes, seems like that example covers most of what I need. Thanks!

By the way, do you know of sample code or documentation for the Android part of the communication?

What you want is very similar to what the official Glucose Profile/Service does, with its Record Access Control Point. In that setup, a Client writes a command to the Control Point, telling the Server which records it want to receive, and the Server then proceeds to Indicate each of those records on the separate Glucose measurement characteristic. You could easily do something similar for your application, making the Client write the record range he wants to have to a control point, and then making the server Indicate or Notify the data on a separate characteristic.

You may also have use in taking a look at nAN-36 and this question. This question (and the one linked in the comment) explains the different roles in play with BLE, while this explains the difference between notifications and indications.
