I know this has been asked a couple of times before, but in all those questions neither the OP's nor the people who answered, provided clear examples. So what I'm trying to ask here is if having a class like this public class MyDatabaseDB { // database constants public static final String DB_NAME = "mydatabase.db"; public static final int DB_VERSION = 1; // list table constants public static final String LIST_TABLE = "list"; public static final String LIST_ID = "_id"; public static final int LIST_ID_COL = 0; public static final String LIST_NAME = "list_name"; public static final int LIST_NAME

Concurrent writing to android database (from multiple services)?

廉价感情. 提交于 2019-11-27 21:29:24
I've a serious problem with android sqlite database and concurrent writing. For better explanations, I will give you a real life example: I've an desktop widget, where I'm showing a list of items from my database (and on background I have DataService, which in regular intervals collects fresh data from my remote server, and update my database with them). So - when i click on some item in list, i need to update clicked item (=do write operation) in database. BUT when i click on item exactly in moment, when DataService is updating fresh data in my database, it of course logs an error like this:

DB File in Assets Folder. Will it be Updated?

旧巷老猫 提交于 2019-11-27 07:17:50
I'm new to the Android SQLite whole thing. This is what I have: I have db.sqlite in my assets folder. The intent of the db is to READ ONLY. The user will not write to it. When the app gets updated, the db.sqlite will be replaced be a new db (I'll delete the old file from the project and add the new one). What I'm concerned about is: Will the old db file gets deleted? (that's what I want; replacing the old one with the new one) Why ask? Because when I debug my app, each time I update the db file, I need to uninstall the app from the device in order to force the update. Will the users need to do

I found many stuff like close the connection and close the cursor , but I do all this stuff.
