I have created a DB in sqlite and a table in this DB. now i want to add one more table in this table.
But am not getting why this new table is not being in DB.

Answer 1

Check out these two links. Sample code is in the second one:

http://developer.android.com/reference/android/database/sqlite/SQLiteOpenHelper.html

http://code.google.com/p/android-notes/source/browse/trunk/src/com/bitsetters/android/notes/DBHelper.java?r=10

You should use a helper class to access the DB and these links will help. If you do it correctly from the beginning, it will save you a lot of trouble when upgrading later down the road. Hope it helps.

Also, in the second link, the DBHelper.java, you can see the creation strings at the beginning of the file in case you are unaware of what to look for.

private static final String DBVERSION_CREATE = 
  "create table " + TABLE_DBVERSION + " ("
   + "version integer not null);";
private static final String NOTES_CREATE =
  "create table " + TABLE_NOTES + " ("
  + "id integer primary key autoincrement, "
  + "note text, "
  + "lastedit text);";
