Sep 20, 2010
I currently facing problem where user have the choice to enter several working experience, where every working experience include several details (company name, duration, roles etc) I don't know how should I store it since users have the freedom to add as many working experience as they have.I have a table as below
private static final String DATABASE_CREATE_WORKEXP =
"create table workexp (work_id integer primary key, _id integer not null," +
"workcompany text, workduration text, workrole text, workskills text" +
"workproject text, worksalary integer, workreason text," +
"foreign key(_id) references user(_id));";
I have a problem while trying to insert / update and delete entries as company name can be duplicated. Any advice or suggestion? I'm glad to provide more info for you to help me.

We have an android app that currently sends data to a php script which writes to a mysql DB on the same server. We are thinking of using a scalable remote DB e.g. amazon RDS.The question is how does our android app write to these remote DBs? Do they have some kind of rest API, or do we have to send the data to the same php script on our server but use that to post to the remote mysql DB?

I'm trying to insert values on Android SQLite Database. The question is, Iḿ trying to insert a word, the table has 3 columns, ID, WORD, COUNT. When I insert a word in the database, some method will verify if this word exists on the database. If yes, it will increment the value of COUNT for this word.

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.

What's the quick and easy way to clear out my Droid's Gmail calendar? I sync two/from Outlook and the cloud, and need to clear off my Droid and Gmail to get things back in sync after some changes I've made. The last time I wanted to do something like this, I emptied (deleted) my Gmail calendar on the web, but for some reason the phone calendar didn't clear out, and I ended up doing a reset to start over. I'm sure there's an easier way, like removing the account from the phone, but it's the primary account and I don't want to delete my contacts from the phone or cloud.

Due to the recent problems with no Sync feature in Kies3, I've had to temporarily resort to using other Apps to sync my S Planner calendar with Microsoft Outlook. Today Samsung have returned Sync to Kies3, which is great, however...
During my use of one particularly rubbish app (that shall remain unnamed), I now have duplicate entries in S Planner for every single event. Is it possible to completely clear the S Planner calendar so that I can re-sync fresh from my PC using Kies3? I've tried deleting the calendar but it won't let me delete My Calendar.

I thought I understood that there was no capability to sync with Outlook via the USB cable so I imported all my contacts and my calendar to gmail and that worked fairly well. Except for contact updates being a pain.
The I discovered HTC Sync and installed that. The result was duplicate calendar entries and some, but not all, contact duplicates on the phone.
I deleted the duplicate contacts and re-sync'd so it removed those contacts from Outlook. Luckily I had just backed up my PST file so I was able to get them back.
How to delete all contacts and calender entries from the phone so I can try again.

If I clear the data in the "Contacts Storage" tab of "Manage Applications" will this only delete the data stored on the phone itself or will it also delete the contact on the exchange server as well? I have some contacts that are duplicates because they were put in the phone before I was able to get the exchange sync set up resulting in an entry for exchange and an entry for phone when in the "People" area.

I have 2 questions though.
1 - how do I change the alert notification for my calendar? Originally it was just the standard alert. When I view the settings there was the option to use the standard droid alert of use a ringtone. So, playing around I cheeked use a ring tone. It brought me to a directory(?) or folder with 4 songs that I had downloaded using railio(sp) ringtones. Now that's the only place I can get to for ALL alerts and ringtones. Even for my contacts it goes to the 4 songs I downloaded from railio ringtones and I can't navigate anywhere else.
I have gone into manage applications and uninstalled the ringtone program, but still can't get out of that spot for my alerts and ringtones. It's driving me crazy!
2 - My contacts have multiple entries for one person.
How can I delete the multiple entries for a contact? When I edit the contact information for a person I see 3 - 5 duplicate entries for one contact. When I first got my droid I synced with 2 google accounts - I didn't know what I was doing --- so, the information under one contact is repeated many times.

public void delete(String id, String name, String phonenumber, String time, String message)
{
String[] args={id};
getWritableDatabase().delete("texts", "_ID=?", args);
}
It works fine, and deletes the specified row. However, I also want to implement it so that I can delete the most recent (earliest date) entry in the database, which should be at the top of the table. I know I can do this by altering the last 2 parameters of delete, but I cannot figure out what to change them to.

But i get following error:

I don´t know what should be the problem. Somehow the values do not arrive in the sql statement. I did nearly the same with the insert method and that worked quite fine.

I have created a list view that displays the names and dates of items stored in a SQLite database, now I want to use a Context Menu to modify these items stored in the database such as edit the name, delete, and view.
This is the code for the list view:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listview);
SQLiteDatabase myDB = null;
myDB = this.openOrCreateDatabase(MY_DB_NAME, MODE_PRIVATE, null);.......................

I need to introduce a menu option on clicking which the whole SQLite database file stored at "data/data/com.company.packName/databases/" gets deleted. Using DROP TABLE command would only delete the table under a particular database.
How can i achieve this?

I 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)?

I 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(...)
private String start_from;
private String destination;
private int hour;
private int min;
private int day;
private int month;
private Source source;
private List<Element> tempList;
private List<Element> routes;
private String startT = "";
private String arrivalT = "";
private String duration = "";
private String line = "";
private boolean first=true;
private List<ResultElement> finalResult;
private List<Element> results;
private DbAdapter mDbHelper;

Ok guys, I got a problem before using Backup/Restore... I notice that everytime I restore my contact, the "STARRED IN ANDROID" check box accumulates (see pix below).. Those unchecked box represents the number of times I restore my contact.
After further investigation, I tried to restore different backup data and found out that the number or "STARRED IN ANDROID" represents the number I backed up my data.
I think, this is one bug of Backup/Restore application that need to be fixed.

I've got a question about updating an app after release. If I have a database that contains 10 columns and I add a feature that requires an 11th column after the app has been released, where would I put the sql code to add the new column so that when they install the app it keeps their current data, but adds that 11th column? Is that even possible or would I need to create another table that references the first with a foreign key?
