May I know how to store an image manually into a database without using codes/programming? How do I go about doing that? How do I even save it as a BLOB type? Or do I save the image URL(from local desktop location and not from the internet) to the database? And after which, how do I go about displaying the image from the preloaded database and display it in the image view?
Many thanks in advance!
I suppose you want to store images on your device, am i wright? As for me the best practice is to save them on SD card and remember the path in DB.
For easy saving you can use bitmap map method compress which receives outputstream to sd card path as a parameter
I have managed to find alternatives to settle down with. Which is to save the image file name into the database and store the images in the application's asset folder after which display the image by the path name in webview.

I want to know how to display the images that has been stored in the database in the home activity in my application.
just store them in regular file system ,create a directory
File file=new File(getabsolutepath()+"/image/")
this path doesn't change so just store the image name in a database.
you can also store images in database using blob https://en.wikipedia.org/wiki/Binary_large_object
but it is not a good practice
I'm using sqlite db in my app and now I would like to allow user customize the background image make them able to select one from their gallery.
Should I just store the path to image and simpy refer to it every time or should I some how transfer the image to some text and store it completely in my db? The second option prevents in case of picture being deleted from gallery. But I would like to know the most appropriate way of doing that.
SQLite has a cursor limit of 1Mb. So, you will probably not be able to store it completely in the DB, when you go to to request it will probably be truncated. Store the path to the image in the database table, and access it that way.
You wouldn't store it as text. Store it as blob to your database. In my opinion this is the way to go (if you use SQLite anyway).
If you have large images then store the path to your storage and not the image to the database.
I think it would be better to save only the path of the background, you won't be limited by the size of the image
In my opinion, the best way to save the customized background image is copy it into the internal storage (private storage) of your application. If you store only the path of the file, then file cannot be available once the user deleted that.
The official docs saying about the internal storage is:
It's always available.
Files saved here are accessible by only your app by default.
When the user uninstalls your app, the system removes all your app's files from internal storage.
i want to display around 1000+ images into an application. Which is the most effective way to store images, on device or in database ?
I am using sqlite database in my app.
Store your image on server than download it in device, save your image into sdcard as a cache or simple image. At download on single success of image store its path into your table and used in your application.
Use Lazy loading concept to load image in application. Its better to store image in sdcard rather than in database.
In android or ios dont save large images into database In sqlite or in core data it can lead to database inconsistency and the database like sqlite are not designed for saving large images.
In android use
Internal Storage or External Storage
In ios use
iOS File System
It will be better if you store the image in server. But if you dont have access to a server, then store the image path in SQLite database and have the images in sdcard. It is always a good programming practice to do like this.
I want to store images locally, So which is efficient way , storing image in data base or storing image in internal memory. I have no option of external memory.
Best wud be to pre bundle the images in your apk itself. Else there is no way to do that.Also if you can save images on the sd card, you can make the folder names start with "." (dot) so that they wont be visible in normal condition (will be visible only if there is option checked of "show hidden files" in your file browser of phone).And if you want that your images dont show up in gallery then just add an empty file to the folder named ".nomedia".This will make your images not to shpw up in Android Gallery.
This page shows the various options you have for data storage. If you just need to save images, I can't see why you would use a database. Also, your database would be located in Internal memory.
Images stored in private internal memory do not show up in the gallery as they are only accessible to the app that created them.
Hi i want to store an image in my android application.I am confused that should i store it in the database or in an application folder?which is a better option and y??
Store it on the SDCard if possible else use application folder.
It depends from the type of image you will want to store. It's confidentially? Or public?
Create a database only for saving an image it would be non-optimal, but it you have a database created, for example to save user profiles (name, surname, birthday, etc), it could be a great option to save a profile image in the database.
Anyway, i think sdcard is the best option. And create a custom folder for your application and save all the images there ;)
Hope this helps...
Its depends on the size of images, you want to provide security to that images etc..
If not bother then store images in a application folder /asset , /drawable or external storage (If use external storage then save path of those images in database) and use it directly, To store in database is quite some ugly way, convert it into blob type and then store, re fetching from database convert into byte to bitmap..
