I am currently working on a project which encrypts a SQLite database file before uploading to a fileserver. It uses "AES/CBC/NoPadding" algorithm in encrypting and decrypting binary input through a user's secretKey.
After downloading (InputStream) the data and decrypting it, loading the database is successful sometimes. However, I don't get it why most of the times, it encounters error which says: 06-18 15:02:42.989: ERROR/Database(1701): SELECT locale FROM android_metadata failed 06-18 15:02:42.999:
