org.greenrobot.greendao.DaoException in android release mode when using androidx

Question

I'm using greenDAO for a long time in my app without any problem! But after migrating my project to using androidX , I received an Exception (org.greenrobot.greendao.DaoException) like below.

Non-fatal Exception: org.greenrobot.greendao.DaoException: app.myapp.models.database.LocationDao@9eff3d3 (LOCATION) does not have a single-column primary key
   at org.greenrobot.greendao.AbstractDao.assertSinglePk(AbstractDao.java:917)

   at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:768)

I searched a lot in google for solving this problem but I didn't find an answer helping me. And this is my model class codes:

public class Location {

@Id (autoincrement = true)
@SerializedName("LocationID")
private long locationID;

@SerializedName("LocationCategoryID")
private long locationCategoryID;

@SerializedName("LocationTitleFA")
private String locationTitleFA;

@SerializedName("LocationTitleEN")
private String locationTitleEN;

@SerializedName("PictureAddress")
private String pictureAddress;

@Generated(hash = 591434765)
public Location(long locationID, long locationCategoryID,
        String locationTitleFA, String locationTitleEN, String pictureAddress) {
    this.locationID = locationID;
    this.locationCategoryID = locationCategoryID;
    this.locationTitleFA = locationTitleFA;
    this.locationTitleEN = locationTitleEN;
    this.pictureAddress = pictureAddress;
}

@Generated(hash = 375979639)
public Location() {
}}

and setter and getters...

Could anyone help me?!

Related to Mr. Markus Junginger's comment, I fixed issue:

"Release mode" is probably a good lead. Please check the following links: github.com/greenrobot/greenDAO#r8-proguard, developer.android.com/jetpack/androidx/migrate, github.com/objectbox/objectbox-java/issues/….

I updated my greendao Proguard codes and fixed problem. A line of codes was:

-dontwarn org.greenrobot.greendao.database.

Changed to:

-dontwarn net.sqlcipher.database.**
