Okay, I have fallen into the lion's pit yet again while using Kindle Previewer. My book is up on Amazon; it works just fine but I wanted to add the cover art to my .mobi file for blog review solicitation. Unfortunately, it's never as simple as pulling up the old Kindle Previewer and adding the image--no. Instead, I had to do an "update" to my Kindle Previewer and now it automatically converts my book into a new file format, .azk, for preview on the Iphone/Ipad, but IT OFFERS NO PREVIEW.
No errors are showing on the generator--it looks fantastic on all the Kindle previews, but when I go to the Apple previews, it converts it and then the preview screen is blank.
WTH??? Anyone know why it's doing this before my freakin' brain melts and starts leaking out of my ears???
The old preview that was available in the iPhone and iPad emulations of Kindle Previewer 2.901 was irrelevant anyway because it showed you the old Kindle Format 6 of your mobi file, whereas the actual iOS Kindle reading applications show you the Kindle Format 8 format (with some vestiges of KF6). You can sideload the AZK file onto an iPad or iPhone via the USB/iTunes route.
Maybe Amazon will get around to creating a good emulation for iPad and iPhone in Kindle Previewer, some time in the near future. But for now, it decided that nothing is better than a wrong emulation. Actually if you build your ebook using KindleGen 1.2 or extract the KF6 part from your mobi file (use KindleUnpack), then both iOS emulations are still working in Kindle Previewer.
As always, man2010, you are the giver of knowledge.
As luck would have it, my mother has an Ipad, I sent my .mobi to it and it works just fine, so whatever upgrade/updates/I-want-to-rip-my-hair-out additions Amazon puts on the previewer, at least I know that it's pretty much hit and miss as I go into it...which is sad because, as a previewer, it's supposed to, you know, preview.
I would recommend e-mailing or sideloading the AZK file instead of the .mobi file to the iPad. If you open the .mobi file on an iPad, this kind of preview doesn't match what iPad owners will see after they purchase your ebook.
