View 1 Replies View Relatedto dear all Android developers, I need to know the UTC bias of my phone to correct the UTC time information I got from a site. I have read earlier posts and already found the solution to get TimeZone information from the "System.currentTimeMillis();" method. However, I need to translate the TimeZone (as like, "Asia/Taipei") to the UTC bias that it has to be (as like, "UTC+8" or other formats). Does anyone know the actual API solution? I have surveyed android.util.TimeUtils and found nothing to do this. The worst solution may I have is to build a "TimeZone/UTC" database table to translate this..

View 6 Replies View RelatedI have a table with column headings: | _id (long) | Name (String) | x (integer) | y (integer) |
I want to delete the row in the table that has Name myName.
// In onCreate
dbHelper = new DBAdapter(this);
dbHelper.open()
// Function in DBAdapter class
public boolean deleteTitleGivenName(String myName)
{return dbHelper.delete(DATABASE_TABLE_2, KEY_NAME + "=" + myName, null) > 0;}
// Function call in java code
dbHelper.deleteTitleGivenName(myName); // this is where my code fails
dbHelper.close();
Just as a note: myName is for sure in the database. Also, I can not use the ROWID since I am getting myName from a ListView.
I just started programming with Android and I have tried for days to solve this problem.
Is my WHERE clause correct (KEY_NAME + "=" + myName)?

View 2 Replies View RelatedIn Android when you upgrade a database all data is lost. I'm going through a phase of development right now that is forcing many database upgrades. I don't want to lose all my data (and have to manually re-enter it) each time I upgrade my database. I would like to store my data in flat files and load those flat files into their respective tables each time a database upgrade occurs.
My questions is: What is the best way to go about this on the Android platform? Where should I store the data files (res/raw???) What sql should I execute to load these files?
I been working on this code dealing with my database for days i can figure out whats wrong. Heres my code: package com.helpihelpyou;

View 5 Replies View RelatedI have a database where I store two different kinds of data. One table is for favorite routes, the other stores the retrieved routes from a server.
I can retrieve the routes etc just fine. But after retrieving the first Route, pressing back or HOME, and then retrieving another route, the routes table is filled with all the old routes plus the new ones.
So my question: how do I delete ONLY the routes table and not the whole database because I don't want to delete the added favorites?
I found the following function in the android docs:
public int delete (String table, String whereClause, String[] whereArgs) and I tried to implement it, but I must pass a SQLiteDataBase as an argument. But how?
I implemented: public void deleteTableRoutes(SQLiteDataBase db){ db.delete("routes", null, null);}
But I want to call this function from a different class where I have no reference to the database.. so what do I have to pass as an argument? Or how do I get a reference to my database?
I build my database upon the code example of the NotePadExample from the dev docs.How to solve this problem?
This is an extract of my class from where I want to call deleteTableRoutes(...)

In my project, I would like to create a database with single table. I would also like to insert data on this table from word or excel document. is it possible? if so please how can I do it? some code snippets would be of great help. I have four different activities which I would like them to interact with this single table. the first is the main activity and its purpose is just to launch the other three activities according to user choice. so it has no interaction with the DB. but the other three activities will read from the table whenever called. Can you please tell me how to call the dbhelper on these activities? I am unable to do this and I am currently creating one db per each activity which is not the optimal way.
