java - How to populate a large sqlite database on first run -


i'm working on dictionary app based on sqlite database on 300,000 rows.

the problem database file in final form consists of full-text indexed tables , weighs on 150mb.

i've managed bring .db file size minimum creating contentless fts4 tables. the database cannot smaller. managed put pre-populated database in app , works fine.

the problem can't keep final .db file in /assets , copy sdcard on first run because it's big. don't want download on first run.

bulk inserting data, transactions , sqlite optimized , no indexes @ start takes forever it's not option.

the thing raw data used build database, in csv format , compressed, 30mb , sqlite's command line .import option fast (100,000 rows in ~1s) but... can't accessed app without root permissions.

i love bundle app compressed csv files in /assets, decompress them, create database on sdcard , import csv seems me impossible. although there many dictionary apps appear doing this. (the downloaded app dozen megabytes, builds database on first run, , takes hundreds of megabytes of space on sdcard).

how accomplish this?

i've been working on past 2 weeks , ran out of ideas. i'm new android development appreciated.

  • plan a: ship compressed sqlite database file , decompress after installation; should able omit indices , rebuild them later.
  • plan b: copy relevant parts of csv importer application, ship compressed csv file , load empty database command line tool would. official documentation page.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
