Sanjay Hadiya :

It is not advisable to store large BLOBS or similar data in the SQLite database. You should use the file system and only store a reference to the data in you database

  1. Generally you should avoid blobs in SQLite as they perform poorly; instead save the blob data as a file and store the location of the file in your DB.
  2. There's a limit of 1MB on internal assets due to dynamic decompression; the 1MB limit also seems to apply to Cursor blobs but this doesn't seem to be documented anywhere.

so you store your image in internal directory and its path is insert in SQLite DB so its easy for you
