I\'m developing an expense tracker where I want to populate the DB with a few records when the application first start. I tried to call the method in my splash activity and add

Answer 1

try to add a flag in your user preferences/shared preferences to check the apps first run and then upon return you can decide if you want to create your db or read it !
have a look here http://www.vogella.com/articles/AndroidSQLite/article.html
EDIT
or just check if dbexists instead of user pref flag

Make a habit of formatting your code well. The last column definition does not have a comma :

    String CREATE_USER_TABLE = "CREATE TABLE " + TABLE_USER 
            + "(" 
            + KEY_ID      + " INTEGER PRIMARY KEY AUTOINCREMENT, " 
            + KEY_NAME    + " TEXT, "
            + KEY_EMAIL   + " TEXT, " 
            + KEY_PW      + " TEXT, "
            + KEY_SESSION + " INTEGER "
            + ")";

    String CREATE_EXPENSE_TYPE_TABLE = "CREATE TABLE " + TABLE_EXPENSE_TYPE
            + "(" 
            + KEY_EXPENSE_ID   + " INTEGER AUTOINCREMENT, "
            + KEY_EXPENSE_TYPE + " TEXT PRIMARY KEY "
            + ")";

private final String SAMPLE_DB_NAME = "TheftData";
    private final String SAMPLE_TABLE_NAME = "UserDetails";
    String CreateTable = "CREATE TABLE IF NOT EXISTS " +
            SAMPLE_TABLE_NAME +
            " (Username VARCHAR, Password VARCHAR," +                   
            " );";

Then in onCreate

protected void onCreate(Bundle savedInstanceState) {
try {
        sampleDB =  this.openOrCreateDatabase(SAMPLE_DB_NAME, MODE_PRIVATE, null);

        sampleDB.execSQL(CreateTable);
        sampleDB.close();
        }

    catch(Exception e)
    {Toast.makeText(getApplicationContext(), " Error: "+e.getMessage(), Toast.LENGTH_LONG).show();
    sampleDB.close();
    }

and to add data

 public void insertData(String username,String password)
    {

        sampleDB =  this.openOrCreateDatabase(SAMPLE_DB_NAME, MODE_PRIVATE, null);

        sampleDB.execSQL(CreateTable);
        sampleDB.execSQL("INSERT INTO " +
                SAMPLE_TABLE_NAME +
                " Values ('"+username+"','"+ password+"');");
        sampleDB.close();

    }

Answer 4

android.database.sqlite.SQLiteException: no such column: exp_type (code 1): , while compiling: SELECT * FROM expense_type Order BY exp_type DESC

This is your error:

String CREATE_EXPENSE_TYPE_TABLE = "CREATE TABLE " + TABLE_EXPENSE_TYPE
                + " (" + KEY_EXPENSE_ID + " INTEGER AUTOINCREMENT" +  
   KEY_EXPENSE_TYPE + " TEXT PRIMARY KEY" + ")

You need a space after INTEGER AUTOINCREMENT

KEY_EXPENSE_ID + " INTEGER AUTOINCREMENT" +  
       KEY_EXPENSE_TYPE

evaluates to:

"id integer autoincrementexp_type"
