How to use Realm database with Java 8 features

由 泪湿孤枕 提交于 2019-12-08 08:05:55
问题 I am new to using Realm database for Android. I modified my gradle files to include the Jack toolchain so that I could use Java 8 language features. I also modified the gradle files to install the Realm plugin. When I synced the project gradle files, I received the following error: Error:Could not find property 'options' on task ':app:compileDebugJavaWithJack' . The two modifications work fine on their own, but for some reason I cannot have both at the same time. I would very much appreciate

Inverse Relationships and UI-Update not working?

由 早过忘川 提交于 2019-12-08 05:47:23

But when I insert a Message into the thread the UI doesn't. public class Messagethread : RealmObject { [PrimaryKey] public string Guid { get; set; } public IList<User

How can I use Realm with newly released versions of Xcode that include new versions of Swift?

由 允我心安 提交于 2019-12-08 05:22:36
问题 I just updated to Xcode 9 last week, and I've been looking for a way to get around this error: Module compiled with Swift 3.1 cannot be imported in Swift 4.0 Each time a new version of Xcode is released that includes a new version of Swift, I have to wait for the RealmSwift project to be updated in order to build and run my project. I am aware that this has to do with Swift's ABI stability, but I also see others who seem to know how to get around this until a compatible version of Realm comes

问题 What's the best way to implement realm in react native(project structure), when you have multiple webAPI methods and tables to store. I'm doing the following is this a right approach or not? If not kindly suggest or provide any link. created a model folder - each js file in this folder have a model class extended with RealmObject. Created a folder for asynchronous tasks - each js file in this folder Calls web api and write data in Realm objects. Every webapi function has a sperate js file.
