Hi, (Am sorry if this question was already asked and answered... but honestly when I searched this group, majority of the answers were relevant to Android 2.1 & 2.2 times. I had also asked this on android platform group lately)
My requirement : If I want to write an application on Android Gingerbread 2.3.4, which displays a list of all images on SD card, can I safely assume that the thumbnails for all images are generated on bootup already? Or is there any broadcast that I must be doing for this to happen ? If the thumbnail generation for all images on SD card, is still going on in the background, would there be any callback available for me to listen to, once its finished (so that I could display a 'loading' dialog in my app) ? Should I have to write my own service which is triggered on each boot, that places a thumbnail generation request for each image found on SD card ? My doubt : I wanted to understand if MediaScanner or MediaScannerService components, which run on every boot, to update Media Content Provider, generate any thumbnails for the images present on SD card (external storage). >From what I could understand from the code of these respective files in frameworks/base/media... there is no call made whatsoever, to generate any thumbnails. However, when I run 'Emulator' for Android 2.3.4, for the very first time, using an SD card setup, I see that a folder 'DCIM/.thumbnails' is already generated with thumbnails present in it. (SD card setup done as prescribed in : http://blog.jayway.com/2009/04/22/working-with-sd-cards-in-the-androi...) Could anyone help me understand the sequence in which thumbnails are generated ? I was so far thinking that it is the Gallery/Gallery3D applications which generate thumbnails, when opened for very first time...
