ClassNotFoundException when ORMLite tries to create database table with an image on android

Question

Hi I am using ORMLite for database access. After I add a table with an image it crashes with a ClassNotFoundException.

@DatabaseField (dataType = DataType.SERIALIZABLE)
private Image image;

The following error occured in the onCreate method of the subclass of OrmLiteSqliteOpenHelper.

Can someone help me out? I tried ORMLite 4.48 and 4.47.

add ECDatabaseHelper:

public class ECDatabaseHelper extends OrmLiteSqliteOpenHelper    {

    private final String LOG_TAG = getClass().getSimpleName();
    private static final String DATABASE_NAME = "test.db";
    private static final int DATABASE_VERSION = 1;
    private static ECDatabaseHelper  instance = null;

    private Dao<Station, Integer> stationDao = null;
    private Dao<Service, Integer> serviceDao = null;

    public static synchronized ECDatabaseHelper getHelper(Context context) {
        Log.i("ECDatabase", "getHelper");
        if (instance == null) {
            instance = new ECDatabaseHelper(context);
        }
        return instance;
    }

    private ECDatabaseHelper(Context context) {
        super(context.getApplicationContext(), DATABASE_NAME, null, DATABASE_VERSION);
        Log.i("ECDatabase", "ECDatabaseHelper () - constructor");
    }

    @Override
    public void onCreate(SQLiteDatabase db, ConnectionSource connectionSource) {
            try {
                    Log.i(ECDatabaseHelper.class.getName(), "onCreate");
                    TableUtils.createTable(connectionSource, Station.class);
                    Log.i(ECDatabaseHelper.class.getName(), "table station created");
                    TableUtils.createTable(connectionSource, Service.class);
                    Log.i(ECDatabaseHelper.class.getName(), "table service created");
            } catch (SQLException e) {
                    Log.e(ECDatabaseHelper.class.getName(), "Can't create database", e);
                    throw new RuntimeException(e);
            }

    }

i think there is problem with external Jar creating folder named libs & copy and paste all needed jar files in that folder see this link to do this

for saving image you need store byte[] fields in ORMLite

@DatabaseField(dataType = DataType.BYTE_ARRAY)
byte[] imageBytes;

for more info see this link

I had added the jars to libs folder in the project. The first table (without image) workes fine! But the new services table raise the error. – corban Jan 09 '14 at 14:35
can you create two table without image? did you test this?i mean create two class without image and create DB for those, did try this? – Shayan Pourvatan Jan 09 '14 at 14:40
I've just commented out the image field and then it worked with two tables. Maybe I should switch to a byte[] for my image. – corban Jan 09 '14 at 14:45
ok it works with byte[]. It's a workaround but does not explain why images do not work. According to [link](http://ormlite.com/javadoc/ormlite-core/doc-files/ormlite_2.html#Persisted-Types) all serializable variable would work also image. – corban Jan 09 '14 at 15:03
`Some databases place restrictions on this field type that it cannot be the id column in a class. Other databases do not allow you to query on this type of field at all. If your database does support it, you may also have to use a Select Argument to query for this type. See section Using Select Arguments.` this is very efficient way to use byte array instead of SERIALIZABLE – Shayan Pourvatan Jan 09 '14 at 15:08
