ORMLite error no databasefield annotations exists

Question

I have this error when I run my Android application:

No fields have a DatabaseField annotation in class [[Lmodel.Vak;

My class Vak has annotations, so I really don't understand why it still giving me this error.

package model;
import com.j256.ormlite.field.DatabaseField;
import com.j256.ormlite.table.DatabaseTable;
@DatabaseTable(tableName = "vak")
public class Vak {
    @DatabaseField(generatedId = true, columnName = "vakID", id=true) Long id;
    @DatabaseField int rij;
    @DatabaseField
    int kolom;
...
}

I have a file called Databasehelper.java in which extends OrmLiteSqLiteOpenHelper and the file looks like this:

public class DatabaseHelper extends OrmLiteSqliteOpenHelper {
// name of the database file for your application -- change to something
// appropriate for your app
private static final String DATABASE_NAME = "project56.db";
// any time you make changes to your database objects, you may have to
// increase the database version
private static final int DATABASE_VERSION = 1;

private DatabaseType databaseType = new SqliteAndroidDatabaseType();

So do you have any advice on this, what should I check?

Answer 1

Could you check, are created table Vak in your DB? The absence of this table can be reason of this crash.

Answer 2

This turned out to be a bug in ORMLite around foreign object loops that was fixed in version 4.22. ORMLite was not properly handing the case where A has a foreign-field B which has a foreign-field to C which has a foreign-field back to A..

Please send me some direct mail @Yanny if this does or doesn't work and I will tune this answer accordingly.

Answer 3

It's probably late for giving solution but this is my solution:
you see proguard try to obfuscating the code and if you read proguard in depth or intro

http://proguard.sourceforge.net/FAQ.html

what Shrinking in proguard -> Shrinking programs such as ProGuard can analyze bytecode and remove unused classes, fields, and methods. so from this we can presume that it is removing your objects since it's not used by anywhere...
so wt you probably need? you need to stop proguard from shirking that methods or objects from process so this is the line for that..:
-keep class com.j256.**<br> -keepclassmembers class com.j256.** { *; }<br> -keep enum com.j256.**<br> -keepclassmembers enum com.j256.** { *; }<br> -keep interface com.j256.**<br> -keepclassmembers interface com.j256.** { *; }

this line will keep proguard from removing my public methods and variables..

-keepclassmembers class classpath.** { public *; }
you need to write column name for atlest id... because it will search for it and will proguard change it's name... so you need to define column name id for primary key..
