When I click on launcher icon of my android app, its crashes immediately. I check logcat error, its shows Migration is required due to the following errors: - Property 'PrintJobData.jobPageCount' has been removed.I'm using Realm database and language is kotlin. How to overcome this issue.
private val realmConfig: RealmConfiguration = RealmConfiguration.Builder()
.name("database.realm")
// .deleteRealmIfMigrationNeeded()
.schemaVersion(1)
.build()
private var realm: Realm = Realm.getInstance(realmConfig)
you can delete your realm if a migration is needed:
.deleteRealmIfMigrationNeeded()
or you can write a custom migration for your realm and each change you make to your database MUST be handled in migration.
NOTE: remember after your changes to your database you have to update schemaVersion
and also add your custom migration to RealmConfiguration.Builder()
like bellow:
val config = RealmConfiguration.Builder()
.name("yourRealmName.realm")
.schemaVersion(2)
.migration(CustomMigration())
.build()
you can learn how to write migration from this and the original document
