[android-developers] Dialog options from a library project?

I've noticed that when developing an SDK library project, there is a desire to have a check as to whether the bluetooth functionality is turned on for the device before proceeding.

However, as a library project, I am restricted to the absence of my own activity.  I had hoped to call the following with the context of the application passed into the library:

          new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);

This was with the hope that it would wait for a reply before finishing.  Since the library is an SDK meant to communicate with a device, it isn't its own activity to override an onActivityWithResult( ) call that I could use to trigger a continuation on the code.  How is typical situation such as these with a desire to have a blocking UI component handled for an Android Library?  I haven't found any decent conclusions thus far.
