Any suggestions for a reader app for Android?

What Android app do you use to read books in Japanese? I've been reading books off of Aozora Bunko on my Android tablet using the program Jade Reader. However, the program loses it's place from time to time. I've also tried out Zo Reader, however it's kind of slow. I should clarify that I am looking for reader apps that have a 1 touch J>E dictionary lookup feature. Any input?
