Android :: Storing Images As Blob In Sqlite

Feb 27, 2009

I am currently trying to store an image into the sqlite database as a blob and retrieve it back.I am not sure if this is the correct approach since i dint find much of sample codes related to inserting images in sqlite. I am able to insert values but when i try retrieving them as byte using decodeByteArray it gives me the following error. DEBUG/skia(13003): xxxxxxxxxxx jpeg error 53 Not a JPEG file: starts with 0x%02x 0x%02x.The image retrieving query works fine as i have checked retrieving an image previously stored as blob in a sample database.I have tried storing and retrieving different image files but i am getting the same error.Could any one tell me as how to solve this problem

Android :: Creating A Drawable From A SQLite Blob

Aug 20, 2010

I'm caching image files as a blob in a SQLite database. I have a similar application on another platform that does the same thing with the same image files. The databases on both platforms report the exact same size for the same images. So I think, but can't guarantee, that the image data is getting into the database intact.But when I try to create a Drawable, the console prints out "DEBUG/skia(267):decoder->decode returned false".

Android :: Storing Double Values In SQLite / How To Ensure Precision?

Jun 21, 2010

i have a problem with double values i need to store in an android homed sqlite database. since these double values represent gps values (lat & lng), i really NEED an absolute precision down to the 9th number after the comma.when reading lng from this table into some (java) double variable, i get a value like "0.999956837" - this renders the values pretty useless to there a way to enforce the precision i need other than storing the values as "text" fields (what would make expensive casts neccessary) or storing them as integers (meaning i need to multiply/divide at each write/read-op)?

Android :: Android Storing Images Downloaded From Web

Jan 13, 2010

I had a question related to whether or not (and how) I should store images loaded from the web. Let's say I am calling a web service from my Android app. In this web service I get a URL for an image on the web. I download and show this image on the left side of a list item in a ListView. My question is, what method should I use for possibly storing the image? Should I.Save it to the SDCard, checking if it exists when the ListView is created (on subsequent requests) and re-downloading as necessary (while updating the image occasionally, in case it changes).Store it in the cache using Context.getCacheDir(), but possibly being forced to re-download it more often since I cannot rely on the image staying in the cache.
Always download it and never store the image.

The image files themselves are fairly small, but I expect some users could have dozens of these small images downloaded/stored. Which would work best, and/or what is the preferred method? As a side question, should I load all of the images in my ListView first (and possibly lock the UI for some time) or load them asynchronously but show a placeholder graphic in the meantime (which might be a bit more "ugly")?

Nov 14, 2010

I am trying to post data to the Blob Store on google's app engine, this code runs without throwing any exceptions, but on the blobstore end there is no log on the post request at all. The server side stuff works when i post using a form (albeit with mime data). I have allowed my android app to use internet. This is a stab in the dark but if any of you folks might have had an issue like this before perhaps the problem i am having might ring a bell

Android :: Load Images In OpenGL Without Having Thin Outline Appear Around Images?

Nov 2, 2009

I'm basically using the same method of loading bitmaps in OpenGL that the SpriteMethodTest example uses and have been unable to get rid of an annoying outline that appears around all of my images.

For example, If I were to load an image of a white circle on a white background, I would expect to see nothing. Instead, I would see my circle because its edge would be gray. In SpriteMethodTest, I replaced the background image with white and was able to see that the edges of the android images flying around also don't seem to be rendered correctly.

Does anyone know how to load images in OpenGL without having a thin outline appear around the images?

Android :: Adding Some Nine Patch Images Breaks All Of My Other Images

Apr 6, 2010

I'm working to convert some background images to nine patch so they scale better on different phones.
The problem is that if I have the following resource structure: drawable-hdpi/background.png drawable-hdpi/button.png drawable-mdpi/background.png drawable-mdpi/button.png drawable-ldpi/background.png drawable-ldpi/button.png and then I drop a new drawable-hdpi/background.9.png file into the mix, it breaks button.png during the pre-compile. The error is "No resource found that matches the given name (at 'background' with value '@drawable/button').Simply removing that one nine patch file fixes the build. Should I be able to have some nine patch images and some normal ones, or to have nine patch only in hdpi but not mdpi or ldpi? This is Eclipse 3.5.1 with the latest ADT.

Android :: How To Deal With Storing Bookmarks

Oct 13, 2009

I am essentially using a listview but am looking at providing a bookmark functionality. I am thinking that I should store the item attributes in a file when bookmarked and retrieve when required to populate a bookmark listview.

I was wondering if there is a de facto standard used in achieving this or do I follow just the "writing into a file" and "reading from a file" when necessary style?
