How android save data in database sqlite in reinstall of application

In my android application, I use database Sqlite, and I enter some records in database from a file .txt, until this all are OK, but after a small period when I run my database, I find that there is no datas, so How can I save datas without be deleted in next run.

One time insert, multiple reads into SQLite Android app

I know there are similar responses so I am going to make this very succinct. I am planning on developing an app which has 18 chapters and each chapter has 30 or 40 hymns. Now, Im planning on using an SQLite command, insert each hymn individually but after the insert, and after the APK file is generated, would the data on the database still be present? Or Does it need to inserted in on each install? What are my options?

If you use sqlite database for you app...every time the app is installed.. new database will be created(of course the old one will be deleted).. and so the hymns will be inserted on each install..(but once you install.. on running your app wont create new database and insertions..).. hope this is clear..

I am not Clear with your question..but if you r inserting data through your code..than on each installation your records would be inserted once..if you provide condition to do so for only once.

You have to code the insertion of the hymns at the start/launch of the application, so that the database is ready for retrieval for the application. But the next time, the application is started, check whether your database exists and has the hyms (size of database), if yes, dont populate the database again, if no, populate it. I hope you want to read from a file/array and insert the records to the database.Once you insert the records to the database, they are available for the reference until the application is uninstalled or the database is re-created. Sqlite database is a persistent storage. Now, Im planning on using an SQLite command, insert each hymn individually but after the insert, and after the APK file is generated, would the data on the database still be present? Yes it would be present. Once the application is installed, the code of database would be executed and the database would be created.

My suggestion to you is use the XML parsing to show the Hymens in place of sqllite. Simply create the xml file with the hymen tag then get the tag and show the data on screen.

Android: SQLite Database. Do we need to create it?

I've been going through some tutorials on working with sqlite databases and they all seem to create a new database, tables, etc on the first run of the application. Is this necessary? What if I already have a pre-built database sitting in the assets folder when the application is installed? Can I not simply just open the connection to said database and start using its information or is there a specific reason everyone wants to create it using sql on first launch?

This question comes up frequently. Try this tutorial to use an existing database on Android:
http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/

You can't use database file which sits in assets folder directly as SQLite database, since this file would not be usual file located in common filesystem. E.g. you can have only readonly access to it. So the only your option is to copy those database from assets folder to device's filesystem.
To handle database creation for the first time and accessing it there's special helper class SQLiteOpenHelper. Read about it here. Specifically look in SQLiteOpenHelper.onCreate() - where should sit database creation (or copying from assets folder as in your case)

It's been quite sometime since I last worked with SQLite databases (in Android) but I believe that when they write CREATE statements, they always do so with the IF NOT EXISTS condition (i.e., CREATE (DATABASE|TABLE) IF NOT EXISTS...).
I don't know what you'll use SQLite for but I believe they do that in Android "just to make sure". That is, if it's the user's first time to run the app, the DB/Tables must be created first else app goes bonkers. Otherwise, they are (probably) created already and this case will be handled by the IF NOT EXISTS clause and they just go ahead and create a connection with the existing DB. Win-win.
(If, for some reason, it is not the user's first time to use the app and the DB isn't there, it will just be created again. But that's obvious isn't it? ;) )

If you just link with preexisting database it wont bind to your system. So there may be failures. Creating db at first run is the most appropriate way to work with db.

How to add database to device?

I have sqlite database in my system i need to add this data base to the device(in the application location).How to do this ????

You basically add code in your application that creates the database the first time it's used (Android will take care of the internals):
http://developer.android.com/guide/topics/data/data-storage.html#db

If your database is not very big - just place your DB file into assets and then during first run your application should just copy SQLite DB file from assets directory to your application data storage. See here

Android SQLite reading

I want to only read data from the SQLite database. When I am creating database and reading it it is working but I have already a database created and I want to read data from this database.
I am pushing the database to the sdcard and trying to run the application but it is not reading form the database. I want to know that if install this .apk file in device then my database will also shift to the device or not.

Common practice is to store initial data on assets/raw folders of application resources. Then during 1st run just create DB using SQL scripts like:
create table if not exist
Fill DB with initial data - and here you're.
