What is the Best practice to store the image in Room database in android?

Question

i got image content uri from activity result like this

val imagePickerLauncher = rememberLauncherForActivityResult(contract = ActivityResultContracts.GetContent(), onResult = { uri->
    it?.let {
        profilePhoto = uri.toString()
    }
})

1. should i convert it to byte array and store it as blob?
2. should i copy the file to app specific folder and store that path to room?

bast solution to do this

Answer 1

Option 1 May or may not be feasible/practical due to how the Android API retrieves data via a Cursor.

• A Cursor is a buffer for retrieving some of the available rows.
  • The Cursor must be able to accommodate/hold at least 1 row, it cannot accommodate/hold part of a row.
  • It's size is limited to up to 4MB.
  • If an image is greater then 4MB then it cannot be extracted directly, it would have to be split into portions. eg How to use images in Android SQLite that are larger than the limitations of a CursorWindow?

Option 1 would, again depending upon the size, possibly (probably) make poor use of the buffering and be inefficient and thus resource intensive.

As such Option 2 is considered the recommended approach even though in some circumstances SQLite can be more efficient/faster for storing data as per SQLite 35% faster than the Filesystem
