[android-developers] Re: Thumbnails
So how exactly does one shut off thumbnail generation? What do the Camera.Parameters settings look like to do this?

Yes, you can have both thumbnail types. It's just another row in the DB. The kind fields would be different for the micro and mini rows. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Thumbnails
One point is still left, can we have duplicate thumbnails of same kind. Say I have an Image, can there be two thumbnails of micro kind of the same image? - No, right?

[android-developers] Re: Thumbnails
We have a number of issues with metadata that need to be sorted out. Unfortunately, it will have to wait until the next major release. Unless I'm mistaken, micro-thumbnails are generated by the music player for album art. This is just an optimization to improve list flinging operations in the music browser.

Hm, it might make sense to add this to the SD card scanner: having us generate thumbnails automatically on scanned content.

We do need a more consistent approach for this.

[android-developers] Re: Thumbnails
Having the camera app create thumbs when a photo is taken is great, but another common scenario has been left unanswered. What happens when the user inserts (or copies) images to the SD card? I've found that unless the Pictures app is run, no thumbs have been generated for the images on the SD card and I have to add the thumbs myself in order to display thumbnail images. Additionally, the gallery/camera apps only create the mini version of the thumbnail and not the micro version. It would be great to have a clear, consistent policy for thumbnail generation of images that reside on the SD card. I can foresee apps battling over thumb creation, some doing it well, others not so well and using different (custom?) sizes for both sizes. That's my two cents.

Unless you override the thumbnail settings, the default is width of 512, height of 384, and quality of 90.

I seen that it can get the contents thumbnails photos, but is not clear how link a thumb photo with the original photo. Somebody know that ?
