Sqlite database is an open source database which provide relation data.It don't need any server or hosting it localy placed in android devices. To create and upgrade the android sqlite database you will need to extends SqliteOpenHelper class from child class. In this way you can create and upgrade your database.

I want that my users can resett the aplicatiom, then I need to reset the sqlite database that I have created. I'm using "context.deleteDatabase("*");" and calling the method tahr create the data base againg.
The problem is: when I delet the database I have to close the app and open it to see the chages. If I dont close the app, I continue with the same database.
to delete your app database try this:
this.deleteDatabase("databasename.db");
the above statement will delete the db file.
How about just dropping all the tables instead?
I am new to android so have very less idea about working of images in sqlite db. I am creating an app in which i will be creating a db with pre-filled data that means i would be putting that data-filled db in assets folder and user will start using it directly once the app is installed.
So i have around 186 images of flags from different countries, which i need to show in a custom listview. Can you tell me how to store all images in sqlite db and get it back to show on listview?
I tried using some IDE for inserting images in db but their decoding doesn't work.
Please help!!!
try this First of all you have to store all images in blob datatype into sqlite database then for retrieving from database user following code
query_compnay_id="Select * From "+mStaticValues.company_master;
mCursor_company_detail=mDatabaseConnectionAPI.ExecuteQueryGetCursor((query_compnay_id));
mCursor_company_detail.moveToFirst();
byte[] by =mCursor_company_detail.getBlob(mCursor_company_detail.getColumnIndex(mStaticValues.image_data));
mBitmap=BitmapFactory.decodeByteArray(by, 0, by.length, null);
I currently have a layout with an EditText field, Datepicker, and a button. I'm trying to find a code that would make it so when the button is pressed, the values of the datepicker and edittext are stored in a SQL file so that it may be retrieved later.
I'm fairly new to using the SQLite functionality on android, and couldn't find a solution to this myself. Thanks!
Firstly read documentation regarding SQLite database from
http://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html
http://www.vogella.de/articles/AndroidSQLite/article.html#overview_sqlite
To store value on click of button follow the steps.
Create DbHelper class extends SQLiteOpenHelper in which you can create table for required values to store in database for e.g. db.execSQL("create table "+EXAMPLE_TABLE+" ("+EDIT+" text, "+DATE+" text )");
Create a class ExampleProvider extends ContentProvider which manages queries like insert, query(select) , delete and update.
After that on click on button retrieve the values from edit text and datepicker , then store it into one object and then using resolver fire the insert query.
Check out from commandline whether values inserted into db or not.
Similarly you can retrieve values from your databases using query() method which retrieve data in form of cursor .
