我应该使用哪种文件类型存储数据库数据

Question

I'm developing a little Android app which is going to be offline, and I need to store the SQLite base's data into a file, that I want to put into the apk's resources, I could use XML or JSON files, but I was wondering if there weren't a better solution.

Thanks in advance :)

Answer 1

If I understand you right you have some prepared data to include in app to use.

If you don't want to parse xml, json or raw file every time you need it in the app you could:

1. Parse the file and put contents into SQLite database on the first run of the app.
Then you can use SQLite to query for data.
You can check if this is first run by checking boolean flag in SharedPreferences upon start of application (in onCreate of your main activity or in Application class)

2. If data is not very big you could parse it once and keep it in memory in your custom data structure.
You can create a singleton to query for this data and parse it in case it is not loaded yet.
