Moving this discussion to the Adobe Digital Editions forum. Tarearhoden please see View e-books | iOS, Android devices - http://helpx.adobe.com/digital-editions/kb/view-e-books-ios-android.html which discusses how to obtain an application which will work on your Android device.
That would be good if Bluefire reader actually worked with Adobe Digital Editions, but it doesn't. Adobe are thieves and DO NOT SUPPORT Adobe Digital Editions properly. Worse still, books cannot even be converted to another format due to DRM protection on the files. You can't read them. You can't convert them. Useless!
