Description
When I developing Android App with the Realm Kotlin SDK, specify a path to the Realm database through the following code
val config = RealmConfiguration.Builder(schema = setOf(Dog::class))
.directory(SystemConstant.DBFolder)
.name("Test.realm")
.build()
In the above code, SystemConstant.DBFolder refers to the path of the external storege card. I confirm that the Android program has obtained the write permission of the external storege card
Realm also created some files in the directory, I thought maybe this is a bug? Realm Kotlin does not allow database file creation on external storege cards?
