Screen Refresh For Kobo Android?
I've been using Android on my Kobo Glo for a while now, and I think it's great. The reader app I like best is FBReader. One deficiency is that there's no screen refresh, so ghosts accumulate with each page turn, and eventually reduce contrast to an annoying level. So I decided to see if I could fix up FBReader with some kind of refresh for this device. It seemed to me that it would be easiest to begin with a stand-alone command that would refresh the screen. I did some searching and found a number of examples that I thought could be made to work. One was quite simple, and although it was intended for a different model, it wasn't too hard to get it to work on the Glo running standard firmware (not Android).
The next step was to see if I could get it to work on the Android Glo. I set up an Android development environment, built my program as a stand-alone command, and tried it. It doesn't work. The program contains one ioctl(), and that fails with errno 25. I tried with some different code that I had found, and the same thing happens. However, it looks like ioctl() calls that read don't fail, just the ones that write.
Is there something special that needs to be done to get output ioctl()s to work on Android?
