Android Efficient Bitmap processing

http://stackoverflow.com – My scenario: In my activity, I have to show 2 galleries, 1 with large image and another is a thumbnail(same exactly like default Gallery application). My doubts: I am planning to save as 2 images(1 with large size and another one with thumbnail size) in sdcard for fast processing. Is that good practice? since it will increase the size. Or Shall I resize the large image during the getView method of BaseAdapter to small size for displaying in thumbnail gallery? Which one is the good practice? I don't want to slow down my app. (HowTos)

I want to get a thumbnail from large size image on web fast.If download the whole file then scale to small size, it will cost lots of resource. Most of images have a thumbnail exif info. So, if there's a method the thumbnail from image exif before download whole image?

i have an custom gallery in my app for that, i am using my own thumbnail directory. here i am caching the image thumbnail and storing it on my own sdcard directory and showing the thumbnail by loading it from custom image directory its working good, but if it has more pictures it takes so long time to load is there anyway to load it fast and i don't use android's default thumbnail directory.

Than

I'm using the standard camera intent to take a photo:

Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(takePictureIntent, actionCode);

And then in onActivityResult()

Bundle extras = intent.getExtras(); Bitmap imageBitmap = (Bitmap) extras.get("data"); mImageView.setImageBitmap(imageBitmap);

Bitmap is a thumbnail.

I know that conky can display images and that the background/desktop wallpaper can be changed. I also know about desklets/screenlets.

hey guys. i am having a serious problem with my thumbnail data my phone is generating. its in /sdcard/DCIM/.thumbnail and its growing like hell... when ever i delete it, it regenerates again when i open my camera app... righit now its size is about 745mb and the size of my pics is not more than 200mb. can't figure it out whats the problem....

I use Nautilus and PCManFM but I need more functionality, maybe you know other file manager which have these functionality:

sort files with grouping by name, type, etc - and possibility to mix all of them thumbnails size regulation by mouse like in MS Windows, because its faster than changing size in settings thumbnails of PSD files in status bar possibility to show image resolution, not only f

Nautilus's thumbnail cache in ~/.thumbnails has grown to several hundred megabytes.

Do I need to be concerned about unrestricted growth of this in the long term, or is its size automatically managed somehow?

Happy May!----------------------------------------------------------------------------------------------------------------------------Please continue to use thumbnails (please try to avoid the large thumbnail imgur.com code) linking to the larger image to help those of us with slow connections. An example of the code needed is below.

Fotoxx lets you navigate an image collection using a thumbnail browser and choose images to view or edit.

Navigate a large image collection with a thumbnail browser, click on images to view or edit. Import RAW files and edit with deep color.
