Question

I would to erase and recreate the database for my app each time I send a new version of my app from Eclipse to my phone (I am developing and changing my database very often). What is the easiest way to do this?

Answer 1

If this is something you do not wish to do once it is live, you can just clear data from your application manager each time. Also, you can make the database version number different and have the onUpgrade destroy and recreate the DB

private static final String DATABASE_NAME = "MyDbName";
private static final int DATABASE_VERSION = 6; 
private static class DbOpenHelper extends SQLiteOpenHelper{

public DbOpenHelper(Context context) {
    super(context, DATABASE_NAME, null, DATABASE_VERSION);
    onUpgrade(this.getWritableDatabase(), 0, 0); 
        // 
    }

   @Override
   public void onCreate(SQLiteDatabase db) {
       db.execSQL(TableHelper1.CREATE_TABLE_QUERY);
   }

   @Override
   public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
      db.execSQL("DROP TABLE IF EXISTS "+ TableHelper1.TABLE_NAME);

      onCreate(db); 
   }

}
