I am working on a library app and have books stored as .sqlite files.

  • 0

I am working on a library app and have books stored as .sqlite files. Each book’s sqlite database file is about 10MB in size. I first tried to put it in assets folder and then copying it to database/ folder but since the file is >1Mb this gives me an IOException. Then I tried to access it from raw folder but its still giving me IOException. So, what is the correct way to access such a file. Also, in future the app might need to download such files from server, so in that case where should I store such database files?

Thanks!!

    Before Android 3.0 you are not allowed to open files larger than 1mb.

    From the link: [P]rior to Android 2.3, any compressed asset file with an uncompressed size of over 1 MB cannot be read from the APK.

    Here are some solutions:

    1. Perhaps you want to look into shrinking the size of the databases, and that might be by making your own, or by removing some of the entries that you do not need/want.

    2. Another solution would be to offload the databases to a server that you have access to and require the application to access the web to get the data that is necessary from this server. I can imagine a nice RESTful API to do this.
