So far we have developed apps in android that create database on runtime. We like to know how can we access a pre-built or existing database/sqlite file in our android app?

View 3 Replies View RelatedI use a sqlite database in my project. The stored data in it must not be available for the user to edit. As I've read here I saw that if you have root access you can alter sqlite database. The only solution would be to encrypt database content, but this would be time consuming for device. Any solution to prevent access to database ?
View 1 Replies View RelatedI'm developing an Android application with a database. That database will have more than three tables. Now I'm working on a class called DBAdapter to access the SQLite Database. DBAdpater will have five methods for every table on database (insertEntry, removeEntry, getAllEntries, getEntry and updateEntry). So, if I have five table, DBApadter will have more than twenty-five methods. I think is so huge. How may DBAdapter classes should be?
View 1 Replies View Relatedi'm trying to access (read & write) from non-default (example 2nd table) table of a sqlite database which i created using sqlite database browser. but somehow, i cant seems to find the way to access it.
Code:
public class DatabaseHelper extends SQLiteOpenHelper {
private static String DB_PATH = "/data/data/com.sg/databases/";
private static String DB_NAME = "TestDatabase";
private SQLiteDatabase myDatabase;
[code]...
select data method works, but i can only select from table 1 and not table 2
I try to increase the value of an integer key in a row in my table. However, nothing really seems to happen.
db.rawQuery("UPDATE table SET key = key + 1 WHERE name=?", new String[] {name});
However, this code works fine (just sets the key to a hard-coded value):
ContentValues values = new ContentValues();
values.put("key", 2);
db.update("table", values, "name=?", new String[] {name});
Also tried '?' instead of just ?, but it resulted just in a run-time error.
I have array list of geopoints
List<GeoPoint> geoPointsArray = new ArrayList<GeoPoint>();
I want to put geoPointsArray array in to SQLite database and then fetch the data back as an array.
Now I use ContentValues for insert into array as:
ContentValues initialValues = new ContentValues();
initialValues.put(KEY_TIME, time);
db.insert(tableName, null, initialValues);
I am trying to populate a ListView in a separate class with data taken from a SQLite database held in another class. What would be the easiest way to do so?

View 1 Replies View RelatedI want to know when a close method of a sqlite database should be called in a life cycle, since the NotePad sample in the sdk (http://developer.android.com/resources/tutorials/notepad/index.html) doesn't call NotesDbAdapter.close(), it implements that method though.
My application accesses the db not so frequently, but some, it depends on user requests. I think I should open the db at the onCreate, and close it at the onDestroy. Is that a good practice?
How can I obtain the value of a boolean field in a sqlite database in android?
I usually use getString() getInt() etc to get the values of my fields, but there does not seem to be a getBoolean() method. Any takers?
How large can be the database of my Android app? Is there a limit?
For performance reasons, I don't want to store the database on the SD card.
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.

View 2 Replies View RelatedI'm currently developing a Field-Service application that stores data in the local sqlite database on an android device. At some point, usually after completing the data collection rounds, the local sqlite db is to be synchronized to a remote sybase db on the server.Any suggestions as to how this could be achieved or engineered as a solution? Or even better, are there alternatives to synchronizing data in such an application?
View 1 Replies View RelatedI already found out that there is no way to bundle files in an .apk and have them on /sdcard, the best option so far being to download the large files upon first run. I came accross a tutorial saying how to bundle an sqlite db with the apk and then copy it so that it can be accessed with SQLiteDatabase (thus doubling the space needed, and not using /sdcard at all).
http://developer.android.com/guide/topics/data/data-storage.html#db says all databases MUST be in /data/data/package_name/databases.
Is that really so? Is there a way to trick the framework into opening a database that is placed on the /sdcard partition? Is there a way to use another SQLite java wrapper/framework to access such databases?
If the answer to the above is 'No', what other options do I have? My data is very well represented in a relational model, but is just too big, plus, I want to be able to update it without the need to reinstall/upgrade the entire app.
I'm new to Android, I just finished the Notepad Tutorials, where we can create SQLite Databases to save notes. So I wanted to know if it was possible to "import" my own SQLite database (not created with my App but with a 3rd-party software) to my project, and if the answer is yes, where should I save my SQLite databse and how can I have access to it.
View 9 Replies View RelatedI'm doing a application that will use a database with serialized object. The objects will be already serialized and the user will just display things. On a PC I would just make an XML but with android I'm not sure. Can I make an XML and "unpack" it when the user launch the application for the first time or should I do something else?
View 3 Replies View RelatedI put my database field in "assets" folder. And use the code from this blog to copy the database to "/data/data/my_packname/databases/", (This copy code i run it in the onCreate() method when i run this app) then use select * from ... to get data. But it gives me the exception: no such table. Someone told me that if i am attempting to copy the file in SQLiteOpenHelper's onCreate(), it's too late. So the copy file code can not copy the complete file. So i need to use adb or ddms to pull the database first? So, Anyone can teach me how to use my own databse?

How do I delete the sqlite database exists in my android? There is a db behind my android qro and delete the same
View 4 Replies View Related
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.

View 4 Replies View RelatedIs there any UI can connect to SQLite database? I hope that I can read the data without writing code.is there any method can make it happened?
View 6 Replies View RelatedIs it really necessary to close an SQLite database that your activity has opened (database is in local memory or on SD card)? I would think it would be good practice, but I noticed that the Android samples such as the Notepad tutorial and SearchableDictionary sample do not do this. I've also seen sample code where the database is consistently opened, read from, and closed, but that would seem to add unnecessary overhead.
