Android :: Best Way To Store Images Within App?
May 5, 2010
I'm just looking for some insight into what would be the best way for me to store images as part of my app.
I have an activity that represents a 'Job' which has a couple of edittext's and underneath was planning on using the Gallery component to show images relevant to this job.
The job data is stored in a database (on the sdcard) so was also thinking of creating a table to store 'JobImages' and having each image stored as a byte array.
But I'm not sure if it would be better to store the images directly on sdcard under a folder structure specific to my application and the job. E.g. using the job ID number as a folder name.
Depending on which method I use will greatly determine the code that goes into an 'adapter' that allows me to bind to the gallery component so before I begin I was wondering if anyone has had the same design problem and what option they chose.

My application requires that when a snapshot is taken it must store in memory and next time when I restart the phone I must get a thumbnail of that photo in list of photos and the full scale photo when I click on it.There are 2 ways I know.
1. Store images directly. Concern here is every time it has to hit directory to get image which takes some time.
2. Store all images in single xml. Concern here is XML will be too big and takes time to parse.

There are a few G1 users reporting that my app won't display images. I can only imagine this is because they don't have an SD card. My app is heavy on images. Is it appropriate to store images on the internal memory? I don't even know if there'd be enough space.

ContentResolver cr = getContentResolver(); Uri pic = Uri.parse("content://media/external/images/media/3");
Bitmap bm = Media.getBitmap(cr,pic); The above code is written in onCreate method of my Activity class. It throws the following error:
08-30 12:27:22.352: WARN/System.err(245): java.io.FileNotFoundException: No content provider: [content://media/external/images/media/3]
What could be wrong? The file in question is there because I launched Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI) in another method and got back the Uri of the picked image from the returned intent.

I guess this question has been asked before, but I can't seem to find a proper answer/solution. Have a note-taking app, which allows to take pictures. For that I start an intent, that starts up the built-in camera-app. So far so good. But when I show that image in my app, it's in a much smaller format The funny/weird thing is, that the camera-app did take a full-resolution picture! But for some reason I can't get the full version to show in my app? So, when I use the standard Android Gallery app, and go to that picture, it is very obvious that it's full size (I can zoom in and see details I really can't see when I zoom in, in my own app). Also, the dimensions are really those of the original picture, taken with the 5MP camera. In my app, they are very small. My phone has Android 2.2, but the same happens on my emulator (Android 2.1). How should I retrieve the pictures in my app? Tried a couple of ways, but none works :( Don't need a complete example (allthough that's very welcome), just a few clues are enough to search for myself.

I am developing an app which uses the phone's default camera application to capture an image and then allow the user to perform some basic editing.I want the image captured to be saved in a location that is consistent with the stock camera application. Can I use the DCIM folder and assume all phones will use that location?

Can anybody advice what is the recommended directory to store files generated by your application: audio files, video files or some images.
If the phone contains SD card, it is clear that files should be saved there, but if there is no any external storage. where would you recommend to save to?

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?

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.

in my application, i want merge serveral images dynamically accroding to the user's selection, and the merged image will be scrolled and zoomed.i extends View to OverlayImageView, which has the properties background Bitmap, layers Bitmap and Matrix. in the onDraw event, i draw the background Bitmap and layers bitmap sequently by the method canvas.canvas.drawBitmap(image, imgMatrix, null).however, if all the bitmaps are stored in memery, it leads to the Out Of Memory problem. so, i have to read the image in the onDraw event by the method BitmapFactory.decodeResource, but it's slow to response user's operation, for example, the scroll and zoom the image will leads to the onDraw event. so, does anyone have some good ideas?
